• "iostat" command different in two equal machines

  - by Oz.

  We have several machines on Amazon (ec2) of the type c1.xlarge with 8 cpus, running the Amazon AMI. Details on the machine: 7 GB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High API name: c1.xlarge One out of the several machines is showing a high load average, since we have run the last yum upgrade a couple of weeks a go. We did not yet update the other machines, and everything looks normal on them. The strange thing is that the top command not showing any hint for the cause of the load. CPUs are - 4.8%us, 1.1%sy, 0.0%ni, 94.1%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st. Mem is about 1.5GB free. Any idea what could it be, or where else can we check? iostat command on the proper machine: avg-cpu: %user %nice %system %iowait %steal %idle 8.97 0.03 4.46 0.19 0.14 86.23 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvdap1 1.60 0.69 55.38 587620 47254184 xvdfp2 2.64 1.10 61.04 934786 52091056 xvdfp4 0.86 0.19 41.72 163866 35601920 xvdfp1 4.37 36.59 73.89 31220810 63051504 xvdfp3 8.03 7.08 94.63 6045402 80749184 iostat command on problematic machine: avg-cpu: %user %nice %system %iowait %steal %idle 9.29 0.04 5.55 0.26 0.11 84.74 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvdap1 2.13 3.34 68.85 246244 5077888 xvdfp1 7.60 74.31 104.88 5480362 7734840 xvdfp3 13.22 73.67 125.00 5433386 9218600 xvdfp4 1.11 0.76 65.08 55762 4799248 xvdfp2 4.16 3.31 99.17 243818 7313264 Many thanks for the help.

• debian 6 losing a large amount of packets

  - by Sc0rian

  I have a rather strange problem. We covered all the obvious hardware related issues (different nic, eth cable and switch) however I cannot seem to stop eth dropping packets. I have 4 servers all exactly the same. driver: e1000e version: 1.2.20-k2 firmware-version: 1.8-0 bus-info: 0000:06:00.0 They are all running the latest kernel(2.6.32-5-amd64).

• Intermittent FTP login issues (Microsoft IIS FTP Service)

  - by JaggenSWE

  I've got a somewhat weird problem which I'm not sure how to troubleshoot. We have a FTP running on a Windows Server 2003 machine using the IIS FTP Service, this is for our clients and is configured with IP-restrictions. However, now ONE of the clients starts complaining that they can't log in to the server from time to time. This is just ONE of 10+ clients that have this issue, which makes me think it's a problem on their side. Just to be on the safe side I had a peek into the FTP logs and found something strange. Whenever succeed in loggin in this is what I can find in the logs: nnn.nnn.nnn.70, userxxx, 2012-06-11, 09:22:32, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 331, 0, [191747]USER, userxxx, -, nnn.nnn.nnn.70, userxxx, 2012-06-11, 09:22:32, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 230, 0, [191747]PASS, -, -, However, if the login fails I see the following events: nnn.nnn.nnn.70, userxxx, 2012-06-11, 09:16:33, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 331, 0, [191739]USER, userxxx, -, nnn.nnn.nnn.70, -, 2012-06-11, 09:16:33, MSFTPSVC1, SERVERNAME, nnn.nn.nn.11, 0, 0, 0, 530, 1326, [191739]PASS, -, -, When you look at the event where the clients sends the PASS in the successful login it seems to know that it is infact "userxxx" that is coupled to that PASS, but when it fails it seems to be lost since user in the PASS event is set to "-". Anyone have any ideas around this, any help would be appreciated. :) //JaggenSWE

• CD/DVD Drive not detecting locally burned CD/DVDs, but works fine with Genuine discs.

  - by Rahul

  I'm using Dell Inspiron 1420 - 32 Bit - Windows Vista, since 2.5 years. I'm facing a strange problem with my CD/DVD-drive. I cannot run/play a CD/DVD which I get burned from my friends. But when I insert Genuine CD, I'm able to play/run it. And when I try to install my Vista package which I got with my notebook, the CD/DVD gets loaded. If I insert a CD/DVD which I get from my friend, CD doesn't get loaded and the system gets hanged. But all these CDs/DVDs work on other systems. I've tested it on many of my friends PCs.

• sporadic routing to another website when opening a common url

  - by user226098

  I have a strange problem in our office: Sometimes when opening a url from one of our projects random url in any browser not the right website shows up but some other website. In most of the cases it redirects to google.com with some parameters like https://www.google.de/?gfe_rd=cr&ei=krOOU8_kGcSKswadyYDQBw&gws_rd=ssl or just the ugly google 404 page). But today it remains on the origial url but shows up the the content of http://debug.netdna-cdn.com/. This happens about 1 time a week and for no apparent reason. Even stranger it only occurs on a single pc in the network. It now happens on two different computers in the network. Both use windows 8. The problem cannot be fixed by clearing the browser cache but by rebooting the pc or using ipconfig /flushdns. So I think it has something to do with the dns cache of the machine. But I have no idea what the reason is for this and how i can figure out how to solve it. Any ideas?

• Postfix character encoding?

  - by Camran

  I use Postfix as a mailserver. I have Ubuntu OS. Then I use PHP to send emails. Problem is that none of my emails are encoded properly by a mailsoftware which my VPS provider uses. According to them, the problem lies with me. It is only the name field which isn't encoded properly. For example "Björn" becomes "Björn" in my emails. However, when I echo the $name, it outputs "Björn" which is correct. Also, gmail and hotmail does show it correctly. The strange part is that the "text" (the message itself) is encoded properly. I use the following for sending mail: $headers="MIME-Version: 1.0"."\n"; $headers.="Content-type: text/plain; charset=UTF-8"."\n"; $headers.="From: $name <$email>"."\n"; $name= iconv(mb_detect_encoding($name), "UTF-8//IGNORE//TRANSLIT", $name); //// I HAVE TRIED WITH AND WITHOUT THE LINE ABOVE, NO DIFFERENCE mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $text, $headers, '[email protected]'); I have tried with and without the iconv line also, no luck. The last thing I can think of is POSTFIX, could there be a setting for character encoding there? Anybody knows?

• Files deleted. What could have happened?

  - by jjfine

  I'm having a weird issue today. I was writing and testing out some simple cgi scripts this morning when I realized that I couldn't run them from one of the other computers on the (windows) network. So I had my network admin come in and take a look at what was going on. A few minutes later a co-worker came in and told me that a bunch of files he was working with as well as a bunch of others (all *.c files) on the network drive got deleted. He also noticed some strange apache_dump_500.log.txt files in the same directories where the files got deleted. The apache_dump_500.log.txt files all look like this: REDIRECT_HTTP_ACCEPT=*/*, image/gif, image/x-xbitmap, image/jpeg REDIRECT_HTTP_USER_AGENT=Mozilla/1.1b2 (X11; I; HP-UX A.09.05 9000/712) REDIRECT_PATH=.:/bin:/usr/local/bin:/etc REDIRECT_QUERY_STRING= REDIRECT_REMOTE_ADDR=<my computer's local ip> REDIRECT_REMOTE_HOST= REDIRECT_SERVER_NAME=<my computer's domain url> REDIRECT_SERVER_PORT= REDIRECT_SERVER_SOFTWARE= REDIRECT_URL=/cgi-bin/trojan.py I looked and I don't have any trojan.py in my cgi-bin folder. And all my apache logs are clean. Windows event logger seems to not have any traces of what happened either. My httpd.conf: http://pastebin.com/Yny2Yh8v I think we've got some kind of virus that added this trojan.py file to my cgi-bin, ran the script, and deleted the script and any traces from the logs. Is this a thing that happens? Any ideas whatsoever would be much appreciated!

• Wireless very slow on one laptop on network, all other machines normal?

  - by th3dude19

  My new laptop (Acer Aspire Timeine 3810TZ running Windows 7 Home Premium 64bit) is acting very strange on my wireless network. Below are the issues I'm noticing... The connection frequently drops. I see the icon change from 'full bars' to 'empty bars with yellow star (meaning no connection)' occasionally. Almost every website I visit (Firefox) hangs for a long time on 'Looking up www.amazon.com' for example. After a long pause, it finally starts loading the website. Neither of these problems exist on any other machines on my network. I also have a desktop running the same OS wirelessly and it works fine. I've run several Speedtest.net tests and the speeds are great (20MBit down/4 up). Results from pingtest.net are as follows: Line quality: D Ping: 46ms Jitter: 65ms Packet Loss: 9% These results are to a server that is less than 10 miles from my residence. The results on the other machines in my house are normal. Any suggestions? This is becoming very annoying as I purchased this machine primarily for browsing.

• Ways to recover data from external hard drive

  - by Howard Benson

  I use an external hard disk for backup of my mac with time machine (OS 10.5.8). I have made something wrong and I have found important folders in the recycler bin. These folders come from external hd. They are backup folders (backups.backupdb) and others. I have tried to restore them draggin and dropping. Some of them came back in the external hd in a while. For the others it takes hours to "preparing to copy" and then it has said "there's no space to copy" on ext hd. It's strange. Files are now in the recycle bin (180gb), and the ext had should have lot of free space. But it isn't really so. Ext hd is not free of space even if these files are in the bin. I ask for advices. I'm not also able to use time machine now (and i have "lost" old backups) for the same reason. Ext hd says that it has not free space.. Thanks

• How I can fix the "Display Driver has stopped responding and has recovered"?

  - by Vitor Rangel

  I'm using a GeForce GTX 580, with Windows 7 64-bit. The driver version of the GTX is 301.42. The problem happens after a few minutes, when I'm playing specifc games. It won't happen in all games - And I don't have any idea why these games doesn't work. The games that doesn't work: Battlefield 3, Civilization V, Sniper Elite V2. The games that work: Mass Effect 3, Crysis 2, Team Fortress 2, Left 4 Dead 2, Skyrim, L.A. Noire. As you can see, it's not a problem of "The games that demand more stop working". I've tryed updating the driver of the graphics-card, the bios of the motherboard, even formated my computer (It was needing it) and instaled every driver in the last version possible. This problem happens since I bought my graphics-card, 6 months ago. After a few minutes, from 10 to 20, the pixels in the monitor become strange, with random colors and effects, like it was broken. Then, everything goes black, and the message appears "Display Driver has stopped responding and has recovered". After that, I need to close the game and start again. I am not overclocking, and my temperature never goes higher than 70ºC.

• Touchpad does not respond when I am holding key on the keyboard

  - by Tadeck

  I am experiencing strange problem with using my touchpad and keyboard simultaneously under Windows 7. I have HP tx2550ew (convertible tablet), and when I hold some key under Windows 7 (eg. space, a, s etc.), the touchpad seems to be blocking. I spotted this while playing Counter Strike. I am not playing much games, and I haven't been playing CS since January, so I am not sure when it started behaving like that. I have tested it also outside the game - when I hold space (eg. when on some web page and entering text into input field) or some letter key, the cursor is not able to move. The problem seems to not be occuring when I hold Shift, Ctrl nor Alt. Did any of you experience similar problem? Do you know what may have caused this? Is there any way I could check what is wrong with my laptop? I have been looking for a solution, but it seems I haven't been looking in right places. This is why I ask question here. Ps. I am unable to test whether this is touchpad-specific, because I have no mouse at my disposal at the moment (got used to touchpad so much I even find it more efficient and haven't been using a mouse with my laptop for months).

  When I try connecting to my wireless network it attempts to connect then gives up. There's something strange going on with the mac's. The eternet switch and all the vlan interfaces have a mac 00:FF:FF:FF:FF:FF. config 'switch' 'eth0' option 'vlan0' '2 3 4 8*' option 'vlan1' '0 8' option 'vlan2' '1 8' config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0' config 'interface' 'lan' option 'type' 'bridge' option 'ifname' 'eth0.1' option 'proto' 'static' option 'netmask' '255.255.255.0' option 'ipaddr' '192.168.2.1' option 'ip6addr' '' option 'gateway' '192.168.1.253' option 'ip6gw' '' option 'dns' '' config 'interface' 'wan' option 'ifname' 'eth0' option 'proto' 'dhcp' option 'ipaddr' '192.168.1.8' option 'ip6addr' '' option 'netmask' '255.255.255.0' option 'gateway' '192.168.1.253' option 'ip6gw' '' option 'dns' '192.168.1.253' config 'interface' 'dmz' option 'ifname' 'eth0.2' option 'proto' 'static' option 'ipaddr' '192.168.0.1' option 'netmask' '255.255.255.0' Any help on this will be greatly appreciated!

• Word 2010 creates multiple processes... sometimes

  - by Bill Sambrone

  I've run into a strange behavior when I migrated our users from Office 2007 / Vista to Office 2010 / Windows 7 (all 32-bit). They use a web based document management system called NetDocuments which stores all their .doc/.docx files. Generally, when they click on a doc from the browser window it fires up Word and opens the doc. Word has an add-in in it from NetDocs as well so it can upload the changed document directly back to the NetDocs server. I get a phone call when Word crashes, and every single time it has crashed I have witnessed multiple winword.exe processes running in task manager. I used process explorer to see what created the process, and it is all Internet Explorer. So far I have rolled them back to IE8 and the problem happens less frequently, but it still happens. When I try to duplicate the problem, I can make it happen sometimes if I open multiple documents very quickly. Using lightning fast alt-tab reflexes, I DO see that a 2nd WinWord process is created when a user clicks on a document, then it closes once the document is open. I think what is happening is that the secondary WinWord process that does some sort of NetDocs voodoo is getting stuck open. This behavior is new to Word 2010 / Windows 7 and google searching isn't coming up with much. I have seen a few posts that this is a known issue in certain circumstances and there is no "fix", but I thought it would good to ask others on this. Thanks!

• HTTP request hangs for for exactly 150 seconds, then gives incomplete response. How do I find out wh

  - by Nathan

  I am hosting a Wordpress blog, and having a strange problem. When I connect to the server (http://71.65.199.125/ at the time of this writing) it displays the Title correctly, and half of a download bar, indicating it has received some of the page, then it hangs for exactly 150 seconds (timed it twice), then it sends the rest of the page, but without the stylesheet. after that it hangs indefinitely, continuing to say "connecting..." without making any progress. If you have any clues as to what might be happening, or how I could print debug logs of PHP or something to see what it is looking for during that hang time that would probably help. recent changed I have made: switched wordpress themes, however I did see it work once with the new theme. moved the server to another building, with an identical ISP, and linksys router forwarding setup. I have also added a favicon.gif file to /var/www but without linking to it from any of the wordpress pages. I have also had a unanticipated power interruption. System info: Ubuntu debian 9.04 Apache2 PHP 5 Wordpress 2.9.2 Thank you

  Hello All, I'm using Community engine. It is really a great job But I encountered a strange phenomenon I couldn't solve it.

• Unable to sync iPod Touch with my PC

  - by alex

  I'm trying to sync a first gen iPod Touch to my PC running Windows 7 64 bit. The problem is that whenever I connect the iPod, iTunes completely freezes (if I start iTunes after connecting the iPod it will simply hang until it's physically disconnected from the PC). I reinstalled iTunes thinking that it had been corrupted, but without any luck. I've had this problem with all the latest versions of iTunes. I've also tried using MediaMonkey and DoubleTwist. None of these apps see the iPod as being connected; DoubleTwist also freezes, just like iTunes. The really strange thing is that I was able to sync the iPod with this PC a while back, but I now seem to have lost that ability. I don't know what changed. Windows detects the device every time it's plugged in (I can see it in Device Manager and I can browse all photos on iPod as if it were a camera). Also, I can sync it to iTunes on Mac OS X without any major problems.

• Ubuntu 12.10, Unity, AMD 12.11 beta drivers, AMD APP SDK 2.7 and OpenCL detection of multiple gpus

  - by junkie

  I'm using Ubuntu 12.10, AMD 12.11 beta drivers, AMD APP SDK 2.7 and OpenCL. I have three amd radeon 7990s plugged in each of which are a dual 7970 so I have six gpus altogether. I plan to go up to eight in a few days. Windows couldn't use even 4 but linux works fine with 6 so far. The strange thing is that the six gpus are only detected by OpenCL in unity (the ubuntu default window manager). If I switch to e17, blackbox or fluxbox or anything else for that matter OpenCL only detects one. I'm using a simple OpenCL program to list all devices to check. I've also checked the output of aticonfig --list-adapters, fglxinfo and clinfo. The first two always show six in all window managers wheras clinfo shows 6 in unity but 1 gpu in all other WMs. I'm also using an X config generated by aticonfig --initial -f --adapter=all. I'm also only using one monitor. I've also checked using lsmod that the fglrx module is loaded in all WMs. So I have two questions. Why does OpenCL see six gpus only in unity? How can I enable six gpus on other lightweight WMs? Basically I'm getting at what determines how many gpus the OpenCL runtime sees? Thanks.

• Creating a bootable USB drive from a distro split over two DVD ISOs

  - by Kev

  I am searching and not finding the right way to do this. Please note, I don't think I'm trying for anything strange here. I just want to make a bootable USB stick of a single OS that happens to be larger than one DVD and happens to be larger than FAT32 will allow for in a single file. On our slow connection I spent a long time downloading CentOS 5.9's two DVD ISOs: CentOS-5.9-x86_64-bin-DVD-1of2.iso (4.4 GB) CentOS-5.9-x86_64-bin-DVD-2of2.iso (718 MB) I have a USB stick that I want to somehow get these two ISOs on. Since the first one is 4.4 GB, I can't use ISO2USB because it insists on FAT32. I cannot find an alternative that lets you specify more than one ISO image--of the same distro, I'm not trying for some fancy multi-boot thing--to put on the same stick. I guess I should have downloaded the CD ISOs, but I thought I was "saving time" because then I wouldn't have as many files to run through the md5 checker. There's no IMG file of the whole thing (only a net install version, which I don't want--I want to pre-download everything) otherwise I would've gone for that. So, given that I have these two DVD ISOs, how can I get them on a stick that will boot and make use of both of them properly to install CentOS somewhere? Again, I don't think this is anything out of the ordinary, yet I can't find software/docs that seem to support this. Am I stuck re-downloading everything in CD-sized ISOs just to do this? I found this, but it doesn't run on Windows. I am using Windows to prepare the stick.

• Load balancing with puppet

  - by Gonçalo Queirós

  Hi there. Im trying to setup a loadbalancing system. My load balancer (nginx) has a conf file where i should list all IP's of the upstream servers. I could put the IP's on the conf manually, but this ways i would need to change the conf file every time i add/remove an upstream server. For now i came up with two different ideas, but i don't like much of neither: 1 - Have every upstream machine to use Exported Resources to create a file with it's IP..Then the load balancer server will have an "include conf_directory/*", and load all the files created by the upstrem servers. Since the load balancer is using nginx this can be done, but if i wan't latter on to configure something that doesn't have the "include" on the conf files, this solution will not work. 2 - If the config doesn't support the "include" command, then we could have again, every upstream server use the Exported Resources to create a filw with its IP, and latter on, the load balancer execute a command that would pick every file and generate the config Both versions addopt the same techinque, the difference is that version 2 is used when the server (that needs to have a conf generated) doesn't recognize a command like "include" inside its own conf. Now, my question is, is there any way to do this in a different form? I suspect that there is, since puppet is made to manage multiple servers, it seems a bit strange not have a easy way to configure load balancers.

• Redeploy using Active Directory

  - by Noam Gal

  I am trying to use group policy to deploy our msi through AD. For some strange reason, when I overwrite the msi with a newer version, and then go to the policy, and click on "Redeploy Application", the application gets uninstalled on the users' machines, and all reg keys, binaries and shortcuts are gone from them. The "Add/Remove Programs" still contain the application entry. I have managed to create a minimal vdproj that does nothing but write its current Product Version to a registry key, and created two versions of it (1.0.0 and 1.1.0). I still face the same problems when using this msi in my AD environment. I did check that my Package Codes and Product Codes are different for both versions, and that the Upgrade Codes are identical. I also checked the RemovePreviousVersion to true. Checking with some other msi (firefox 3.0.0 and 3.6.3) I downloaded from a site specifically for AD deploy, it worked just as expected (first installing the 3.0.0, then I over-written the msi, and clicked on "Redeploy", and the users got 3.6.3 after the next log-off-log-on). What am I missing here?

• Is there a historical computer peripherals or accessories museum or even just a current list?

  - by zimmer62

  Thinking about all the unique and different peripherals I've owned over the years, from ISA capture cards, to parallel port controlled shutter glasses for 3d games. I've seen many many accessory or computer peripherals come and go. The nostalgia of these things is a lot of fun. I tried to find some sort of historical time-line or list but what mostly turned up is computers themselves. I'm more interested in the mice, scanners, the weird adapters that shouldn't exist, short run very rare products, strange devices from computer shows in the 80's and 90's... Hardware you might find in a geeks basement that would be completely useless now, but was the coolest thing around when it was new. An example would be a drawing tablet I had for my TI-99 computer, or the audio tape player accessory for a C64 which let you save files to audio tapes, An ISA card that did the same for PC's hooked up to a VCR. Remember that IBM-PC Jr upgrade kit, that added a floppy drive, more memory and the AT switch in the back? I'd love to find either a wiki, or a list that has already been assembled which contain many of these weird (or common) accessories. I've had so many over the years I suppose I could start a wiki here if such a list doesn't already exist.

• Windows 7 caches FTP credentials?

  - by Martin Booka Weser

  On my remote maschine i have an iis 7.5 (win server 2008) and set up an ftp site with iis manager authentication. I then did active directory user isolation and isolated my users to physical folders according to their names. So far, so good. I can access with ftp cliens from everywhere with different test accounts that i previously set up in the iis manager auth. Every user connects to its own folder. When i now tested with windows 7 as a client i did the following. Explorer - computer - right click - add network address - the ip of my remote maschine - user1 - password1 Perfect - it works. I now want to connect with user2. So I deleted this network address and set up a new connection, but with user2 (or even anonymous) instead. Now the strange thing: Windows doesn't even ask me for a password again. It just connects me to the folder of the user1. I already disabled ftp caching in the IIS and i disabled the user1 account in IIS manager authentication! Still, if i set up a network connection with this windows 7 it connects to the folder user1 . No matter which username i use (anonymous, administrator, user2,...). And if i connect with other ftp clients or other computers it all works perfectly. So I assume that this one windows somehow caches the credentials... But then, why does the IIS still accepts this credentials even if i disabled this user1 account??? Thanks.

• Why is writing to my external hard drive slow, while benchmarks show fast writing?

  - by matix2267

  I have an iOmega eGo 320GB portable drive connected through USB2.0 to my laptop running Windows Vista. It's been working fine for quite some time until recently it became very slow when writing e.g. when copying ~300MB movie over to the drive at first it is extremely fast but it actually doesn't write it only puts in cache and then hangs on last 10-20MBs for about a minute. When copying larger files it's the same story: starts fast but then slows down to ~5MB/s (sometimes even slower down to 2MB/s). Strange thing is that I have always had caching disabled for this drive (it was disabled by default and I never bothered changing it). At first I thought that the disk is dying so I checked S.M.A.R.T. values and everything is fine there. I also run chkdsk and it seemed to fix the problem - it worked fast for a few minutes but then it slowed down again. I also tried plugging it into another USB port - no difference. Additionally I noticed that reading under certain circumstances is sometimes slower e.g. loading times for some games are ~10 times longer, whereas simple copying files from this drive to my internal HDD is fast. I ran a speed benchmark using CrystalDiskMark with a 5x100MB run and strangely got these results: read write (MB/s) Seq 33.05 28.25 512k 17.30 15.27 4k 0.267 0.372 4kQD32 0.510 0.260 This is different from what most other people have (I've found many threads about slow disk write while googling but all of them were slow on benchmarks too) which is why I decided to post this problem here. BTW most of the time when writing (or sometimes reading) the activity led is mostly idle (blinks a while and then stops for longer, sometimes has slower blinks ~1 sek, sometimes goes off for a few seconds - extremely long blink :) ) but when benchmarking, defragmenting or just reading (copying from this drive, installing apps from installers there, watching HD videos) it is blinking really fast (like it should) and there are no slowdowns. It shouldn't be driver issue unless stock Windows drivers have some issues I'm not aware of.

• USB transfer speed for Windows 7 is incredibly slow to my external drive

  - by Wolfram

  I'm running Windows 7 Pro and am try to backup 116 GB of data to my external 1 TB hard drive. My laptop has only USB 2.0 ports and my hard drive is USB 3.0 compatible, as is the cable I'm using. I understand that the transfer speed should still be in accordance with USB 2.0 speeds. However, right now I'm getting 135 KB/s and it's been gradually dropping. For an earlier transfer, I would get between 4 MB/s to 8 MB/s. So, I'm really just wondering what's going on with my transfer rate and what I can do to improve it. I'm currently about 35 GB into the 116 GB transfer. Another strange thing is that the window which shows the transfer status decided to max out at 835 MB, and therefore shows items remaining as 0. However, it is still performing the rest of the transfer, and I can see it still cycling through files. Now that I think about it, it seems plausible that the speed being shown by the window is calculated merely as total data transferred / time elapsed. Since the "counter" of data, as far as what is being displayed in the window, maxed out at 835 MB, as time increases, the speed shown is going to keep decreasing because the 'total data transferred' value isn't being incremented. So with that in mind, I suppose I don't actually know at what rate the data is being transferred currently. Nonetheless, my best speed earlier was only around 8 MB/s. Shouldn't USB 2.0 deliver closer to 35 MB/s? Also, if someone can tell me why the transfer status window is displaying the incorrect data information and how to fix this, that would also be appreciated.

• Ubuntu via Wubi refuses to show up in boot menu

  - by Redandwhite

  I'm in this strange situation: I have 3 partitions, one for Vista (C), one for Windows 7 (D), and one 10GB partition (E). At least that's how my original OEM Vista partition sees them. The primary OS that I boot into everyday is Windows 7. The situation is that for some reason it sees the Windows 7 partition (its own) as drive C, the 10GB one as (D) and the Vista one as (E). I've successfully used the Wubi installation before on Vista, but now it simply doesn't work. Ubuntu just does not show up in the boot menu, no matter what I try to do. I'm running out of ideas. I heard it doesn't really play well with Windows 7 either. I set it to Vista compatibility mode and that didn't work, I also tried installing it from Vista itself and that didn't work either for some reason. Any ideas what I should try? If anyone is about to suggest EasyBCD, please underline the command-line instructions I'm gonna need to follow. Thanks.
