There is a bit of (dated) information on that here:
I wouldn't recommend using Drive A mode. Here is some more
information from an Iomega .pdf manual:
When emulating a floppy drive, the Zip drive�s firmware uses two
different formatting variations:
The ATA IDENTITY PACKET DEVICE Command (A1h) reports �Floppy� at
word offset 44
The drive adds 32 to all LBAs specified in all commands, thus
making the first 32 LBAs unaccessible and reducing disk capacity
CAUTION If the drive is in drive A: mode and a disk is formatted
using an old version of Iomega Tools, the newly formatted disk will
be unreadable in other Zip drives. The old Iomega Tools, which does
not recognize drive A: mode, and will lay down a second 32 LBA
partition on the disk. All updated versions of Iomega Tools that
supports drive A: mode (including IomegaWare software) are backward
compatible and will support previous Iomega drives.
