I have a generic USB 2.0 hdd drive caddy and hdd and it didn't take too much effort to get it to work (IANA guru).

First I made a directory to mount to. This was simply /mnt/usbhdd. Then I tested it out with
# mount -t vfat /dev/sda1 /mnt/usbhdd

no problems. I found the device following some suggestions elsewhere on this forum. It was too much hassle entering this each time I started the laptop, so I added the following to the bottom of my /etc/fstab...

/dev/sda1 /mnt/usbhdd vfat defaults,rw,user 0 0

(remember to include a carriage return at the end of the file or it won't work)

One annoying thing is that the drive must be connected before I start the laptop (this includes mounting manually).

After that it was a simple shortcut to the new hard disk directory on the desktop. It's a FAT32 partition like yours, and it appears to have no probs. The speed is fine, even going over a USB 1.0 port.

Hope this helped.
