    Have I just destroyed a partiton??


    Hello everyone,

    I think I may have just messed up royally!!

    I took the plunge and installed Linux Kubuntu 6.06 last night. I installed Linux to a partition on my larger (Slaved) HD and everything seemed to be okay. When it was done, I took out the CD and rebooted. Again, nothing odd happened except that I was having trouble viewing the files on my existing HD's (got an error saying the drives had not been mounted), but I now know why I got that message.

    HOWEVER... When I restarted back in XP, I noticed that one of my pre-existing partitions has now vanished!

    In it's place, I now see it listed as only a 'Local Disk' - and now XP is now asking me if I would like to format it!

    When I installed Linux, I purposefully chose a very small size for new Linux partition - ~8 Gb. My original Windows setup for that secondary HD had 3 partitons. All but one had more than enough space to handle losing 8 Gb to Linux. The 'missing' partition had ~10 GB of space used and at least 20 GB free space.

    Have I lost that partiton forever??? What can I do to get it back???

    I would still like to use Linux (dual booting for the moment), but I think I need a lesson in how to install it properly so it and XP live in 'relative' harmony.
    What I'll probably end up doing is move XP to my larger drive and giving Linux exclusive reign over my smaller drive.

    Thank you!

    Here is some information on my setup:

    Current hardware configuration:
    AMD K7 Athlon 2.6 Ghz CPU;
    ASUS A7N8X-X MoBo;
    512 MB DDR RAM;
    Celestica Gold Edition RADEON 9200 128MB
    WDC WD153BA Master HD 16 GB; WDC800JB-00ETA0 Slave HD 80 GB;
    LITE-ON LTR 32123S 32x12x40x RW, Sony DVD-ROM DDU1615
    ATI TV Wonder PCI Card;
    and an old Creative AudioPCI (ES1371,ES1373) (WDM) sound card

    Here is what Linux says about my current partition setup:

    Disk /dev/hda: 15.3 GB, 15382241280 bytes
    255 heads, 63 sectors/track, 1870 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes

    I believe the case is: Windows cannot natively recognize ext3 partitions. ext3 is the formatting scheme that Ubuntu (and Kubuntu) use; Windows WILL NOT see it, but it is there!

    If you want to view your ext3 (linux!) partition under Windows, try this: http://www.fs-driver.org/

    OK, you have one primary partition, NTFS type,
    and an extended partition containing four logical partitions.

    Two of those are NTFS, one is Linux, and one is swap,
    so if any former windows partitions have disappeared, yes it is lost.

    You may have one anomaly that makes your Linux partition appear to Windows,
    and appear unformatted. I have seen this before. Partitions have type numbers.
    Your extended partition is type f W95 Ext'd (LBA). The logical partitions within
    it will appear to Windows, even if they are Linux type, because of the type number
    of the extended partition. You could use fdisk to change the type.

    There is more than one extended type. Choosing the right type will make your
    partitions invisible to Windows, and remove the temptation to format them.
