• Cloud based backup solutions based on open standards?

  - by Rick

  I am looking for a solution to backup and consolidate important media from a couple Windows laptops and Mac laptop. I would like a solutions that based on open standards, so my data isn't trapped by proprietary formats and proprietary protocols. I would like the ability to switch clients or change providers in the future. For example, something like Jungle Disk plus S3 sounds like a great option. However, I am having trouble confirming how or if this can be setup meeting this criteria. Are there any real or de-facto standards for treating S3 as a filesystem? If so, what Windows and Mac clients support these standards?

• Does the advanced format tool bundled by manufacturers actually do anything which mkntfs doesn't?

  - by neurolysis

  I recently bought a new drive (specifically, a 2TB Samsung Spinpoint) that says on the label that it supports advanced format, and that I should download the tool from their site. Unless I'm missing something, mkntfs has always had its maximum sector size at 4096b: -s, --sector-size BYTES Specify the size of sectors in bytes. Valid sector size values are 256, 512, 1024, 2048 and 4096 bytes per sector. If omitted, mkntfs attempts to determine the sector-size automatically and if that fails a default of 512 bytes per sector is used. Will this tool on Samsung's site do anything other than format the drive in the same way doing mkntfs -s 4K /dev/sdb1 would do? To be specific, I'm intending to use this drive on a machine that will primarily run Windows XP, but I'd rather boot into Linux/BSD and format the disk manually than have bloated software. I do want to have the new AF style sectors though -- that's essential. So if I did the command above, would it have exactly the same effect as using the advanced format tool?

• Windows 7 x64 CD to MP3 ripper

  - by marc_s

  I'm trying to find a good, simple CD-to-MP3 ripper to copy my physical CD's to my computer's hard disk. I'm running Windows 7 Professional x64 - and that appears to be a major problem. All the "usual" free- and shareware tools I've tried (CD-to-MP3, Visual MP3 and quite a few more) seem to have trouble with either 64-bit Windows, or with my HP CD/DVD built into my HP Compaq Elite 8100 machine. Does anyone have any good recommendations? I don't want to install a monster like iTunes - something really clean, small, simple would be fine. Free- or Shareware - if it works reliably and with good quality output, I'll be happy to register! Any hints are welcome!

• Combine drivers from multiple Win7 installs to single image

  - by MikeyB

  I need to prepare a Windows 7 image with drivers for multiple systems (Lenovo laptops). I currently have an image prepared on one laptop type but need to grab the drivers appropriate for the other laptop types as well to ensure that it works on all systems. From what I can tell, the procedure will be: create a boot CD with imageX take a .wim image prepared on the first type of systems take .wim images from the other systems mount the other images in WAIK extract the drivers from the other images inject the drivers into the first .wim boot a system with the boot CD and redeploy the updated .wim image into the Windows partition take an image of the drive with usual imaging tools This all seems a little too convoluted, but I'm willing to do it to get the proper drivers into the image. This is (seemingly) necessarily complicated by having more than one OS on the disk image. Am I on the right track?

• Prevent EC2 machine from halt, poweroff, shutdown

  - by Adam Matan

  Hi, EC2 Ubuntu servers erase all disk contents when being shut down. Following an unfortunate accident, I have decided to prevent the command-live halt, poweroff and shutdown. What's the best way to do it? I thought about renaming these commands (at /sbin) to something like HALT_RENAMED___ERASES_ALL_DISK_CONTENTS. Are there any files, other than the three listed above, that needs to be handled? I've noticed that halt and poweroff are merely links to reboot. Should reboot be renamed, too? Adam

• Enabling DMA in pc with windows 7

  - by Mugen

  I was checking my pc settings using AIDA64 (supposed to be the successor for Everest - it basically shows you detailed hardware you currently have). For my ATA hard disk it shows the setting for DMA as "supported, disabled". But when I checked the windows setting I see that it is actually enabled. How can I find out which is correct? And if its disabled what do I do to enable it? Thanks for your help. Here are some screenshots for this:

• CentOS - dual boot from new partition

  - by Dima

  I need to install two copies of the CentOS 5.5 (bank A and bank B) on different partitions of the same hard disk and install grub boot loader to another partition (visible from both banks). The boot loader should redirect the boot menu to bank A or bank B (according to the configuration). The new partition is mounted to /common_partition and grub is installed on it using following command: grub-install /dev/hda In the new partition I'm created the following menu.lst file: title BOOTCONTROL REDIRECT : PLEASE WAIT root (hd0,1) configfile /boot/menu.lst boot On my setup: both partitions (bank A and bank B) are primary and grub is installed on MBR. The problem is: but the new boot loader (on common_partition) did not load. What wrong on my configuration?

• Centos expanding directory

  - by Ansell Cruz

  I currently have a file server, all the files are installed in /usr/local/nginx/html/. The setup is 1 hard disk with 1TB of data. This 1TB of storage is all used up. I asked the guys to add 2 HDDs with 2TB each. This new HDDs will be used for new storage of files. Now, if I mount this 2 new HDDs into /usr/local/nginx/html/, the current files in there will be deleted. My goal is to expand the storage in /usr/local/nginx/html/ without losing data in it. Would this be possible?

• Strange performance from RAID5 using WD RE4 disks

  - by Howard

  I've noticed a bit of a performance issue with some WD RE4 drives I'm using under AMD's hardware RAID solution. First a bit of background: Environment: Windows 7 home premium x64 HDD's: 3x 1TB WD Raid Edition 4 in a RAID 5 setup with 128 kbyte stripe (2TB usable space) Testing Tool: HD Tune, process set to "High Priority" Processor: AMD Phenom II x6 1100T Ram: 16GB DDR3/1600mhz Motherboard: MSI 970A-G45 The image below pretty much depicts the issue I'm having. Every test has the same thing, a period of similar length where the performance drops to a few megabytes a second. This can't be a TLER issue as the purpose of RE4's is to work around that. Any help would be greatly appreciated.

• Difference between tcp recv buffer and tcp receive window size?

  - by pradeepchhetri

  The command shows the tcp receive buffer size in bytes. $ cat /proc/sys/net/ipv4/tcp_rmem 4096 87380 4001344 where the three values signifies the min, default and max values respectively. Then I tried to find the tcp window size using tcpdump command. $ sudo tcpdump -n -i eth0 'tcp[tcpflags] & (tcp-syn|tcp-ack) == tcp-syn and port 80 and host google.com' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 16:15:41.465037 IP 172.16.31.141.51614 > 74.125.236.73.80: Flags [S], seq 3661804272, win 14600, options [mss 1460,sackOK,TS val 4452053 ecr 0,nop,wscale 6], length 0 I got the window size to be 14600 which is 10 times the size of MSS. Can anyone please tell me the relationship between the two.

• eAccelerator ignore my new setting?

  - by Mwebe Nkrumah

  Hi, Im using eAccelerator 0.9.5.2, CentOS 5.3, lighttpd 1.4.22 But because eAccelerator is cached in RAM, I needs too much RAM. So Im trying to cache in hard disk. (my website is not generate money, so Im thinking about cheaper solution) So, I modify /etc/php.d/eaccelerator.ini with below codes: extension="eaccelerator.so" eaccelerator.shm_size="12" eaccelerator.cache_dir="/var/cache/eaccelerator" eaccelerator.enable="1" eaccelerator.optimizer="1" eaccelerator.check_mtime="0" eaccelerator.debug="0" eaccelerator.filter="" eaccelerator.shm_max="20M" eaccelerator.shm_ttl="1800" eaccelerator.shm_prune_period="0" eaccelerator.shm_only="0" eaccelerator.compress="0" eaccelerator.compress_level="9" eaccelerator.keys="disk_only" eaccelerator.sessions="disk_only" eaccelerator.content="disk_only" So, the output of phpinfo() as below: http://img175.imageshack.us/img175/1104/screenshggot.png But after using "disk_only" in eAccelerator and restart lighttpd & php-cgi using killall, my RAM usage is still high for php-cgi. Reboot the server also not works. The data is created in cache directory, but RAM usage is still high.

• Dell Inspiron/Windows Vista sleep/hibernate issue

  - by sarge

  When I hit the sleep button in Windows the computer looks like it's going into Sleep mode but a few seconds later it's restarted, and stops with this error message: internal hard disk drive not found To resolve this issue, try to reseat the drive. No bootable devices--strike F1 to retry boot, F2 for setup utility Press F5 to run onboard diagnostics. The computer is running Windows Vista (SP2) and I have installed all available Windows Updates and the latest manufacturer drivers. I have already tried to reseated the drive, ran the onboard diagnostics and there were no errors. I have changed the power settings for all devices where it's available so that they are not allowed to wake up the computer. Any ideas?

• Vista won't boot - just get black screen

  - by DisgruntledGoat

  When I boot into Windows Vista (Ultimate), I just get a black screen (with the mouse visible and working). If I run in safe mode, it seems to pause for a while when loading crcdisk.sys. A lot of research says it could be a problem with the hard drive, but I dual boot Ubuntu and that works fine and I can still see and use the Windows partition absolutely fine from Ubuntu. I tried using the "startup repair" option on the Vista install disk but it didn't detect any problems. I have run chkdsk several times, with this: chkdsk C: /f /r And also drive D (the recycle bin). The first two times it detected and fixed errors on the C drive but now it doesn't detect any errors. Is there anything else that could be causing this problem?

• Laptop harddisk produces clicking sound

  - by Alfred James

  This happens when I am booting up into windows, shutdown or things in which I access the harddrive excessively. It doesn't happen all the time. I have checked it with "Crystal disk Info" and it displays no problem, and shows HDD to perfectly fine. Should I be worried about my HDD? I have Hitachi HDD in laptop. Some times my harddrive temps reach upto 43C while watching movies or playing games. What are the normal temps, which are safe for HDD to operate and increase the lifetime of HDD. Thanks

• Connecting OS X MacBook Pro to DirecTV DVR

  - by user14293

  I have a DirecTV DVR which soon will be replaced. The local phone carrier has wired fiber-to-the-door and that DirecTV sat service will soon be history. I have irreplaceable video recordings on the DVR's disk I would like to salvage. I'd like to connect my MacBook Pro (OS X 10.5.3) to the DVR (male HDMI to male Thunderbolt) and treat the MAC as a TV monitor. I'd like to capture the video stream to a file and then burn it to DVD. This is for my use only, not for distribution. Still researching video capture. Don't yet have a solution. Maybe there isn't one. Any ideas?

• SBSMonitoring.mdf reached limit

  - by Bastien974

  I have SBS 08 Standart. I have some Error in my Event Viewer with MSSQL$SBSMONITORING Event id 1105, 1827: Could not allocate space for object 'dbo.EventLog'.'PK_EventLog' in database 'SBSMonitoring' because the 'PRIMARY' filegroup is full.

CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 4096 MB per database. I tried to schrink the database, worked for SBSMonitoring_log.LDF but nothing for the SBSMonitoring.mdf, still 4096MB. I don't know how to reinstall the monitoring. Thanks for your help.

• Disable or sleep secondary hard drive in Macbook

  - by cpak

  I've done some quick Googling but didn't find an answer. I've put an SSD in my Macbook, and at the same time moved the original hard drive to the optical drive bay. I'm running the OS and most of my daily apps off the SDD so the hard drive is really just for storing stuff I need now and then. Now I'd like to disable (as in power off or "force sleep") the hard drive when I don't need it. Tried unmounting the disk using diskutil unmountDisk but it kept spinning for like 10 minutes. Maybe that's to be expected, but I'd imagined it would stop instantly on unmount. Also, it would be nice to have it disabled by default, and only mount it (= power on) when I need it.

• HTC Android Fails to mount- Mount from computer?

  - by Ben Franchuk

  I Have an HTC Incredible S (S-Off, Rooted, ViperVIVO 1.3.0 ICS) that has seemingly ceased to posses the ability to mount its SD Storage to my computer. For whatever reason, whenever I plug in my device to transfer files from computer to phone and vice versa, the computer, for some reason, cannot actually aces the phone. I get prompted with a window on my phone when I first plug it in, asking me which mode I want to put the device into (Charge mode, tether mode, etc.), and even if I select the "Disk Drive" function, the phone still cannot successfully mount to my computer. The phone itself unmounts itself from the SD and says that the computer is connected, but again, it doesn't work. Is there any way to force mount the device from my computer- either via command or otherwise? This should help in that if I unmount the SD from the phone I should be able to mount it to my computer, from my computer, Correct?

  I used Acronis True Image Home 2010 to clone a Dane-Elec zLight 8Gb pen drive/USB flash drive to a PNY Attaché 16Gb USB flash drive. Now WinXP shows the drive in device manager as USB DISK 2.0 USB DEVICE but doesn't have it in My Computer/doesn't assign it a drive letter. What is it that has messed up the PNY Attaché and is there some way to repair it so that it can be used as a regular USB flash drive again? Is there a safe way to clone a USB flash drive to another larger one? How safe is it to backup and restore a USB flash drive to/from a drive-image?

• Test/Dummy SMTP server for Windows

  - by geoaxis

  I would like to install a Test/Dummy SMTP server on a Windows 2008 server (virtual box). I just want to test my web application on the machine it self so I don't need the mails to go out on the internet, but just to be written to disk (so that I can verify that the mail function was indeed called and the correct data was handed over to SMTP) Can you recommend some tool. I guess starting your own SMTP server in python is an option. I am looking for a simple (ready to use) solution, targeted for tests systems. I will need to integrate it to automated tests (Selenium) at a later stage. Thanks
