SYMPTOMS

When you use an Iomega Zip IDE Insider drive to re-partition and reformat a Zip cartridge using LBA mode, the cartridge will be unreadable from other SCSI, Parallel, IDE Zip drives (operating in non-LBA mode), or ATAPI Zip drives.

CAUSE

The standard translated geometry for all Zip drives is 512 cylinders, 12 heads, and 32 sectors per track. LBA translation of the drive geometry results in a translated geometry of 97 cylinders, 32 heads, and 63 sectors per track. Zip drives using standard Zip disk geometry will be unable to read the alternate disk geometry presented by Zip cartridges formatted under LBA mode.

RESOLUTION

In the computer's CMOS setup, disable LBA translation on the Zip IDE Insider drive. Enter the correct cylinder, head, and sector information, as indicated above.
