  • Speed of TrueCrypt whole disk encryption

    - by Gareth
    I'm getting a new development laptop soon, and I'm thinking of using TrueCrypt to encrypt the whole disk. What kind of performance drop can I expect? 10%? 30%? more? Also, assuming the workload has an effect, would compiling/using Visual Studio be affected much? I cannot seem to find anything like this on the web.

  • How to identify heavy write to disk?

    - by Darth
    I have this problem with server running CakePHP application. The server is insanely slow, I first thought that it's application problem, but then I found constant 5-6MB/s write to disk. What is the easiest way to find cause of such a heavy write? The server is running Gentoo.

  • HP DL380 G7 Disk swap to a HP DL380 G6

    - by rnuno
    The HP DL380 G7 has 3 SAS disks in RAID 5 configuration. I need to change that server to another task and instead of make a clean install on the HP DL380 G6 can i just swap the 3 disks from HP DL380 G7 to the HP DL380 G6? I expect some driver issues maybe on the OS itself because the processor is different. They both use Smart Array P410i, if i power down the machines swap the disk by the same order will the RAID 5 configuration remain and the OS will boot?

  • Is keeping the primary hard disk as disk C: still relevant?

    - by Jeremy French
    Back in the day, floppy disks were a: and if you were lucky b:, then when permanent storage came along c: was the default for hard disks (as I remember it) Now that many computers no longer have floppy disks is it possible to have your primary hard disk as A: is the convention out dated? Removable drives (like DVDs and flash readers) now seem to take lower precedence than permanent storage so it is a bit of an oddity that floppy disks should have higher letters.

  • System Event ID 11 Disk

    - by Guy Thomas
    Upon starting Windows Server 2008 R2 I get this error message: Event ID 11 Disk The driver detected a controller error on \Device\Harddisk3\DR3. There are also also 3 more similar messages for Harddisk 2, 4, and 5, but not zero or 1. Checking the event viewer reveals it's been going on for 3 months. I ran chkdsk - no bad sectors. Any advice on the cause, better still, a solution?

  • How do I mount a raid disk

    - by Devator
    So I screwed up my grub.conf file on a CentOS system and I'm in recovery right now (it's only a test dedicated server). My disks are /dev/sda1 and /dev/sdb1 (RAID 1). Now I need to mount /dev/sda1 and make changes to the grub file, however those changed need to be reflected on the second disk aswell. How do I mount these RAID disks? I can mount one using mount -t ext3however it will damage the RAID array.

  • Decrypting Windows XP encrypted files from an old disk

    - by Uri Cohen
    I had an old Windows XP machine with an encrypted directory. When moving to a new Win7 machine I connected the old disk as a slave in the new machine, and hence cannot access the encrypted files. Chances don't seem good as documentation warns you: "Do not Delete or Rename a User's account from which will want to Recover the Encrypted Files. You will not be able to de-crypt the files using the steps outlined above." On the other hand, I have full access to the machine, so maybe there's a utility which can extract the keys and use the to decrypt the files... BTW, I didn't have a password in the old machine, if it's relevant. Ideas, anyone? Thanks!

  • External USB disk drive cannot be remounted in Windows XP

    - by jackhab
    I have Maxtor Basics Desktop 1TB external USB drive connected to Windows XP. The dirve's firmware puts it to sleep after 10-20 min of inactivity and then the drive cannot be mounted unless I reset it via power connector. While in sleep mode I can see the device in the Device Manager under both Disk drives and USB sections. Is there a way to get the drive out of sleep mode without hard reset? Thanks

  • USB stick appearing as hard disk drive, not removable storage device

    - by Paul Lammertsma
    I just plugged in a very simple 1GB USB stick from the office in hopes of making it a Fedora Live USB stick. For that to work, I need a removable storage device, or else it won't appear in LiveUSB Creator's list. Explorer lists my USB stick as a hard disk: LiveUSB Creator indeed doesn't show it in the device list: Is there any way of forcing Windows to see the stick as a removable storage device?

  • Best filesystem choices for NFS storing VMware disk images

    - by mlambie
    Currently we use an iSCSI SAN as storage for several VMware ESXi servers. I am investigating the use of an NFS target on a Linux server for additional virtual machines. I am also open to the idea of using an alternative operating system (like OpenSolaris) if it will provide significant advantages. What Linux-based filesystem favours very large contiguous files (like VMware's disk images)? Alternatively, how have people found ZFS on OpenSolaris for this kind of workload?

    - by veggiemexicalidog
    I have one disk partitioned into 2 logical drives, C and D. There is no unallocated space. I need to add space to C: so I want to use some space from D (plenty available). How can I do this without losing data on D:? Edit: This is a Windows machine.
