    is the MBR on thumb drive the same as it is on harddisk ? I always thought that they are very different as some of them have security feature(as a boot device) which makes me think that they must be special.

    Re: Fix MBR on thumb drive

    --I use a CF card with a Dazzle USB reader/writer. I tried partitioning the card with Linux but it screwed up the filesystem in Windoze. Dazzle provides some software to "reset" / reformat the CF card, so I used that. (This is all in Win98 BTW.)

    --Go to the mfr's site and see if they have any utility software. If they don't (you should always try the "native" windoze solutions 1st) you can try the 'install-mbr' prog in Linux.

    ' man install-mbr '

    --What I ended up doing is having a loopback file on the drive for native-linux filesystem (ext2.)

    After you get it fixed:
    ' cd /mnt/flash ' (or wherever it is)
    ' dd if=/dev/zero of=blahblahsisboombah.mnt bs=1M count=50 ' == Create 50 meg file
    ' mke2fs -m1 blahblahsisboombah.mnt '

    ' mkdir /mnt/blah ' == Create a mount point for the loopback

    ' mount /mnt/flash/blahblahsisboombah.mnt /mnt/blah -oloop,noatime '

    Here's what my CF looks like:
    Code:
    fdisk -l /dev/sde
    
    Disk /dev/sde: 8 heads, 32 sectors, 490 cylinders
    Units = cylinders of 256 * 512 bytes
    
       Device Boot    Start       End    Blocks   Id  System
    /dev/sde1             1       490     62704    6  FAT16
    --Sample Entries for /etc/fstab:
    Code:
    /dev/sde1  /mnt/flash   auto defaults,auto,noatime,user,suid,exec,rw 0 0
    /mnt/flash/usrlocalbin.mnt /mnt/usrlocalbin auto defaults,loop,auto,noatime,user,suid,exec,rw 0 0
    --If you leave the drive partitioned, Windoze may not like it.
