That is what I'm using right now, a pair of 300GB USB. The large amount of holding disk I have on this system is not needed, but it helps more when I do archive dumps to tape. Filesystem Type Size Used Avail Use% Mounted on /dev/hda2 ext3 19G 12G 6.9G 62% / ... /dev/sda1 ext2 280G 223G 58G 80% /vt/1 /dev/sdb1 ext2 280G 206G 75G 74% /vt/2 /dev/hda6 ext3 114G 6.8G 102G 7% /hold/disk1 /dev/hdb6 ext3 74G 181M 70G 1% /hold/disk2 You could leave the prepared FAT filesystem on the disks. I chose to reformat and put a regular linux filesystem on them. Realizing that there would be very few files on those disks, compared to the number or inodes created by default when running mke2fs, I used options to specify a more reasonable number and gaining an extra few percent capacity for data. BTW make sure you have usb 2.0, not 1.1 interfaces in your computer. I had to get an extra card to update my old box. Before getting the card I did try an create the filesystem. Took 13 hours to run mke2fs :) -- Jon H. LaBadie [EMAIL PROTECTED] JG Computing 4455 Province Line Road (609) 252-0159 Princeton, NJ 08540-4322 (609) 683-7220 (fax)
