• Snapshots are disappearing from Time Machine. Why?

  - by AntonAL

  I have TimeMachine enabled for my external HDD. I'm triggering backups manually 2 times per week. I have noticed, that some snapshots, that i made, are gone. I noticed this behaviour several weeks later, but i had doubts. To make it sure, i've recorded screen video with listing snapshots in TimeMachine. After watching my screen recording today, I'm sure, that for Augusut i had 9 snapshots. Now, i have only 3 of them. What's happening ? I had no crash disk reports, errors etc

• Windows XP occasionally hangs for 2-3 minutes as the splash screen fades in.

  - by marcusw

  This is a bit of a rare problem, I have not been able to debug or fix it or find anyone else with the issue. I hope someone here can help me out. Once in a while, I boot up Windows XP from the first partition of the first disk (using grub, the computer dual-boots ubuntu) and it hangs as the Windows XP splash image fades in, leaving the screen with a dim image of the splash screen. After 2-3 minutes, it continues to boot as normal, no error messages or strange behavior. I have noticed that this happens about 75% of the time when the last time the computer was shut down it was from Ubuntu, and maybe 5-10% of the time otherwise. I have looked at system logs as far as I was able, and did not find anything the miss. What is causing this and how can I fix it?

• Restoring raid 5 array after bios flash

  - by cogergo

As you see it shows one disk in the array but for some reason not the other two! Click for image of raid configuration error

• Computers with Small Capacity SSD - For caching?

  - by RXC

  Recently, in newsletters from websites, I have been seeing computers for sale from manufacturers that include an HDD and an SSD but the SSD has a small capacity like 24 GBs. I don't know if this still holds true, but I learned that when building a computer, you would want to install your OS on your fastest hard drive. I do a lot of PC gaming, so I install my OS and games on my SSD, because I learned that games and many applications make lots of system calls to the OS and performance can only be as fast as the slowest piece. Why these computers come with small capacity SSDs? Most OS's take up around 20 to 30 GBs of space, so what are the benefits of such a small SSD? Are these small size SSDs for caching? and what exactly does caching mean (what does it do and how does it help)?

• How can I set `less` or `more` max lines (scrollable height) limit/boundary in linux?

  - by Rudie

  (Sorry for the title. Any suggestions?) I've set my commandline PS1 to cover 3 lines: white space user, server and pwd $ or # to input I think less (or more?) is configured to break after window's height - 1, because when I do a $ git log, the first two lines are invisible at the top of the window and the rest is scrollable. I'm not sure who handles this scrolling and its configuration, but I assume GIT uses less/more. Where can I configure that my scrollable window is window height - 3 lines and not window height - 1? More info: If I cat lines.txt | less with a 23 line file, it shows the entire file and no scrolling. If I do the same with a 24 line file, it doesn't show line 1 (and no scrolling). With 25 lines: doesn't show lines 1 and 2 (and no scrolling). With 26 lines: shows line 1 and scrolling! The less breakpoint is at the wrong height...

• What is a good "free-form" ("type anywhere" or canvas-like) text editor? [on hold]

  - by scorpiodawg

  My 5-1/2 y.o. son is starting to use a computer and one of the things he likes to do is to type stuff into an editor. He has used TuxPaint before and is familiar with the idea of a "canvas" for painting stuff (where painting anything anywhere on the canvas is fair game). When he opened the text editor (this was gedit on Qimo Linux), he attempted to do the same thing -- he pointed the text cursor to an arbitrary location within the editor window and expected to be able to type there (like a "text canvas", if you will). I had to explain to him that he would have to press Enter a few times to create new lines, as well as press Space a few times to create columns before he could do that. This is sub-optimal. My question: are there any free-form, canvas-like text editors that I can have him use? Almost like hex editors of yore. I am not interested in getting him to create "text areas" in a paint program.

• Preparing a hyper-v VM image

  - by Anteru

  We have a Hyper-V Windows Server 2k3, and we're hosting multiple VMs on it. However, right now, we always start the VM creation right on the server, i.e. when preparing a new Ubuntu image, I just install it into a new VM and set it up and when I'm happy we store the disk image. I wonder if there is a way to prepare a hyper-v image locally on my desktop machine instead? I'm running Windows 7, and I would love to be able to set up a VM so that we can copy the image over to the server and be done with it. This is for linux images only, and we definitely need the hyperv network integration. Is there a recommended way how to prepare hyperv images without running a hyperv instance somewhere?

• Would SSD drives benefit from a non-default allocation unit size?

  - by davebug

  The default allocation unit size recommended when formatting a drive in our current set-up is 4096 bytes. I understand the basics of the pros and cons of larger and smaller sizes (performance boost vs. space preservation) but it seems the benefits of a solid state drive (seek times massively lower than hard disks) may create a situation where a much smaller allocation size is not detrimental. Were this the case it would at least partially help to overcome the disadvantage of SSD (massively higher prices per GB). Is there a way to determine the 'cost' of smaller allocation sizes specifically related to seek times? Or are there any studies or articles recommending a change from the default based on this newer tech? (Assume the most average scattering of sizes program files, OS files, data, mp3s, text files, etc.)

• How to move a Windows instance to a different EC2 data centre?

  - by Darren Cook

  I've a Windows EC2 instance running in one region and need to move it to another region (Tokyo and Singapore in this case). Is that even possible? What potential problems do I need to watch out for? (I found http://stackoverflow.com/questions/2181849/ec2-instance-cloning which is describing how to do it, but appears to assume Linux instances, and to assume the same data centre. Is it possible to move my keys across to another region?) I tried something similar with a Windows instance a few months ago, just trying to clone it in the same data centre, but I couldn't get it working quickly, so I had to give up and just create a fresh instance at that time. This time I've got a bit of breathing space, and want to research how to do it properly! Root Device Type: ebs Block Devices: sda1 xvdf (both are ebs, "attached", and have Delete on termination set to "no"; sda1 is the root device) The AMI is described as "Unavailable" (then an ami number).

• Weird noise coming out on Windows 7 when harddisk activity at peak?

  - by Curious Apprentice

  I'm having a very strange problem. I'm hearing a "choooooooooo kkkrrr" sound (Its not like the normal sound speakers make when powered on) all the time. When there is more Hard Disk r/w activity the sound increases and as HDD r/w activity slows down so the sound. I have two other OS installed on my system. I have tested, it only happens when I'm on Windows 7. I have no clue what the hell is happening !? Any help would be greatly appreciated. Here's the sample of noise: http://www.ziddu.com/download/20852917/noise.mp3.html

• Vostro 1520 crash during bios update

  - by Deadmilkman

  My Vostro 1520 (P8700 C2D) originally came with BIOS A02. This bios version have known problems with VT, so I had to upgrade to A05. During the upgrade, the notebook crashed. Needless to say, it won't boot anymore. The simple question is: is there a way to access the bios boot block to recover the bad flash with a crisis disk? I know that the MINI and the ALIENWARE models have this feature, but I can't seem to find anything about it in the Vostro machines. Any help will be much appreciated. PS: Dell's solution is to change the motherboard, but it will take several days, as the board isn't available in my country :( Regards, Deadmilkman

• VPN on PC vs Mac

  - by allstar

  I am trying to connect to a VPN from my home computer, as opposed to my work computer which already has the network info set up. I have received instructions on connecting from a mac, but since I don't have that I'm trying to do the equivalent on my PC. I know the: server group name secret and my own login account and password Using the Windows 7 VPN, there's space for: Internet address destination name user name password domain (optional) I'm trying to determine what's what. I assume the internet address is the server. I've tried using the "secret" as the Password, b/c i'd think the first part is connecting to the VPN as opposed to logging in. It still wants a user name though. I tried mine, I tried the "group name". I would appreciate your help with this. Thanks!

• How to I configure a swap partition using swapspace

  - by jcalfee314

  I finally have the swapspace project installed and running (via init.d). The purpose is to have a dynamically re-sizing swap partition. I'm clueless however on how to use it. It has good documentation but just does not go into that last step. How to I configure a swap partition using swapspace? The process is probably the same for any 3rd party program that would provide a swap space implementation to the kernel. I know this was intended to run as a process because the project provides an init.d script.

• Can I sleep one of the displays on a dual-monitor setup? [duplicate]

  - by archedpenguin

  This question already has an answer here: Can I sleep one of the displays on a dual-monitor setup (running Windows 7)? 4 answers I want to be able to 'put the display to sleep' on one of my two monitors when it isn't needed, so it doesn't distract me or use unnecessary power. Ideally, the display would be asleep, but the OS would remain in dual-monitor mode, so I could still have a variety of windows open in the sleeping monitor's display space, which would mean I wouldn't have to keep switching between single- and dual-monitor modes. Its the same as "Can I sleep one of the displays on a dual-monitor setup (running Windows 7)?" I just wasn't sure I could comment on such an old thread. None of the answers there provided a perfect solution and I was wondering if there is now a solution available.

• What is the point of connecting two routers directly together

  - by rubixibuc

  The way subnets work, wouldn't connecting two router interfaces together require their own subnet between them. Unless that subnet mask has 31 bits, wouldn't that was adress space. I'm asking because I often seen that done in networking books. How can this be done without wasting IP Addresses? They usually draw this when explaining subnetting. They have a central router connected to several other each one supposed to be creating their own subnet. Is this really how subnettimg is done? Example <-------[Router 1]-----Wasteful Subnet-------[Router 2]------> | | | \/

• “BAD” partition showing up in Partition Manager

  - by Quintin Par

  I tried to partition my primary hard disk (NTFS partitions) with qtparted and got stuck in the process. Consequently I had to kill the process and exit my knoppix live CD boot up. Even though I was expecting XP to get corrupted, it booted fine and showed up all the drives accessible. But when I opened this with partition manager 8, it shows up as “BAD”. I ran chkdsk /f without any success. My objective with qparted and partition magic was to resize my existing partitions and add some space to c: How do I fix this problem and resize my partitions? Edit: Here's how my primary drive as per Windows is:

• Move 2TB Win7x64 to 640GB HDD

  - by reedacus25

  Basically I just got a new (refurbished) HP H8-1260t to use for Windows Media Center. The shipping drive is a 2TB Hitachi drive, but I have an older and barely used 640GB WD Caviar Blue 7200RPM drive I would like to move my Windows install to. I have about 750GB of data with over 1TB free left on the drive. Having googled my heart and fingers out, I would think that I can shrink my partition down to the size it is full at now with over 1TB free for a second partition where I can move my media files to further shrink my boot partition so that I can fit a system image smaller than 640GB on that WD drive. I want to have a separate drive for Media and TV Recordings from my boot disk. Does this sound like the easiest method for me? Or am I doing this all wrong. Help appreciated.

• A require a server hosting package that would be suitable for several .net managed applications, accessed only by me

  - by user67166

  Hello, I currently run a server at home consisting of SQL Server 2008 .net Framework 2010 VPN Connection ASP.net Web Services running around 5-6 applications supporting a financial trading system that i regularly use. THe only user is me. Recently the requirement to have these applications running in a 24/7 100% uptime (or 99%) environment has become important. No longer can I both meet this requirement and host my server at home on my network - so i am looking to move to a dedicated hosting company. After some research, the only real companies I can find offering such services are geared towards company web-space hosting. I don't need 1TB+ bandwidth, what i need is CPU, Memory and as much control over the environment as possible. Does anyone have any examples of such a service? Thanks in advance.

• How to remove a drive from a 2-drive RAID 5 array?

  - by DrSAR

  There is some information available on shape changes in RAID arrays but I'm a little nervous and would like confirmation: Problem: I have 2 500GB drive as software raid 5 (mdadm). I would like to free one of the two drives since RAID-redundancy is for wimps... Can I just mdadm --grow --array-size=1 followed by a mdadm --grow --raid-disks 1? This seems too simple. How would I specify which drive gets freed? Part of the reason for this maneuver is that I don't have additional space to run a backup.

• Server 2003 saying unlicensed

  - by nat

  I came in this morning to our windows 2003 server - running only SQL server 2005 saying it was unlicensed. When logged straight onto the box as soon as I got past the login, it popped up the click yes to license, did that and it would just loop back around to the login. It wouldn't turn off, couldn't remote to it, after a power off and reboot, it magically decided it was in fact licensed. It didn't appear to be low on disc space or other resources. Logs not showing anything out of the ordinary. Has anyone else experienced this, or might have an idea as to what just happened? Any help much appreciated.

• Harddrive speed drops a lot!

  - by AZ

  The hard drive is used to do BT with uTorrent. Recently uTorrent began to report there is a "I/O Device error", then I use HD Tune to test it, it turns out the transfer rate is only 16 MB/sec. At the same time, I have a similar hard drive tested, it rates as 120 MB/sec. They are both 7200rpm desktop hard drives. I used chkdsk to fix it but the rate didn't change. Is this a symptom of hard drive failure? Should I backup the content on the disk ASAP or is there any other tool can fix it or diagnosis it?`

How can I force it to shut down without having to wait for this?
