Hello Paul, > Zip drives have partition tables. I am aware of that, or I would have advised Jimmy to use /dev/sda, not /dev/sda1. /dev/sdax because the usb zip drive is an emulated scsi drive. > Most of my zip drives are /dev/sda4. > I've also got one which uses partition 1 (it was supplied with some > software which I deleted) and that's /dev/sda1. You are correct. I forgot to mention that the disks that come with the drive I occasionally use are from a Mac user. Mac partitions these disks sanely (using partition 1), but now I remember that Windows uses the fourth partition for some silly reason. So yes, /dev/sda4 should be the correct device to use.
