I need to copy a lot of diskettes on our RT running AIX 2.2.1. I have two 1.2 Mb floppies. If I use: dd if=/dev/fd0 of=/dev/fd1 it takes a ridiculous amount of time. Is there a faster way? (Maybe the right way?) .....rob -- EMAIL: rob@maccs.dcss.mcmaster.ca <<< Standard Disclaimers Apply >>> ARCHAIC: Steltech, 1375 Kerns Rd., Burlington, Ontario, Canada, L7P 3H8.

Try: dd if=/dev/fd0 of=/dev/fd1 bs=256k I did the same thing. You'll be amazed at the difference ... -- | "Pain, n.

I have copied disk by copying the device as a file in the past. i.e.: cp /dev/fd0 /disk1 cp /disk1 /dev/fd1 This works well and may be faster. -- Kevin-john Conway ...a librarian from hell...
