that I have found has helped me out.
Has any one in the group had this happen to them and how did you remove
the write protection.
I cannot see any special files on it except 2 of my own.
Any suggestions out there?
Thanks

Hi Mike!
There are a load of Window$ type repair suggestions here (Since this is a known bug in Xp SP2):
http://www.techspot.com/vb/all/windows/t-18654-USB-Flash-Drive-Write-protection.html
Linux solutions are going to be basic drive management:
plug in usb flash drive and mount (if you don't have automouter)
dmesg to verify the device:
# dmesg
# mkdir /mnt/usbwork
# mount /dev/sda1 /mnt/usbwork
(it might whine that you didn't specify the type if so:)
# mount -t vfat (or NFS) /dev/sda1 /mnt/usbwork
# cd /mnt/usbwork
Copy off your old files
# cp -r * $HOME
# umount /mnt/usbhome
# fdisk /dev/sda
Remove all the partitions using the "d" command.
create new partitions using the "n" command (you only really need one big one)
set the file type "W95 FAT32 (LBA)" (or ext3 if making a bootable Linux distro) "t" (types will display)
if this is going to hold a distro set the bootable flag "a"
check your work: "p"
save "w"
Lay on a file system (that matches your file type):
mkfs.vfat -I -n USBDRIVE /dev/sda1
Your drive should work now just fine!
