    Fat32 partition corruption, unknown type.

    I've been using an external hard drive (formatted as fat32) for a couple months, storing almost all my data, my programs for a separate XP partition, and uh.. just about everything else (including a project I've been working on in blender that is very important to me) inside this disk. Recently I unmounted the partition, resized it, leaving a few gigs for expansion, formatting the other, now empty, partition to ext3. Initially, this partition was r/w only for root, but after a little searching, I ran nautilus through gksudo, then changed the permissions through that so that I was the owner. Now the problem lies with the FAT32 partition.

    While running Deluge, downloading a few files, It gave me an error (can't remember what it was). I opened the disk, looked around, and saw every filename (Actually, way fewer than I had) with crazy symbols, except the folder deluge had been writing to. I unmounted the partition, hoping to get a look at it, run fsck on it, but running fsck returned only this:
    Code:
    Checking file /
    /
      Contains a free cluster (2). Assuming EOF.
    FAT32 root dir starts with a bad cluster!
    After searching for a few hours, well.. frankly.. I don't know what that means, and I don't know how to fix it.

    (Oh, I forgot to mention.. Long time reader.. First time poster. (I had to say it.))

    Try using TestDisk to check your FAT32 drive.
    Steady movement is more important than speed, much of the time. So long as there is a regular progression of Stimuli to get your mental hooks into, there is room for lateral movement. Once this begins, its rate is a matter of discretion.

    Re: Fat32 partition corruption, unknown type.

    Code:
    ~$ testdisk /dev/sdb1
    
    Unable to open file or device /dev/sdb1
    it can't find the partition. It can find the new ext3 partition though, through the name of the folder it's mounted to..

    Edit: (I can't mount the fat32 partition, so this isn't an option..)

    Post whatever displays when you run:

    Code:
    sudo fdisk -l
    and

    Code:
    sudo blkid

    *Do post your /etc/fstab file
