I think that's a device-dependent behavior, tho. Didn't for me, but I only ran eject 2 times. I did not want to add unnecessary wear on the motor since it spins up and back down. I'm sure it is with scsi, but I don't have a zip drive. (Didn't see the need, 100mb is nothing nowadays) -- Lab tests show that use of micro$oft causes cancer in lab animals
