Could be a lot of things including a bad drive but a few other causes of I/O
errors come to mind.

Covered write protect notch - notch must be uncovered and toward the left
                                                hand side of the drive

Damaged write-protect switch

Using High density disks

Dirty drive heads

If you have two drives you might try swapping the connectors on the Disk II
card
