Now you make me access the "way back machine"......


A "simple Google search" with "OS/2 Zip Drives" 
http://www.google.com/search?as_q=OS%2F2+Zip+Drives&hl=en&num=10&btnG=Google+Search&as_epq=&as_oq=&as_eq=&lr=&cr=&as_ft=i&as_filetype=&as_qdr=all&as_nlo=&as_nhi=&as_occt=any&as_dt=i&as_sitesearch=&as_rights=&safe=images>

found this with the first link:

============================================================================
HPFS Formatted Disks
OS/2 users will be especially interested to know that you can format a 
Zip disk with the HPFS (High Performance) file system. However there are 
some caveats you should be aware of. HPFS is designed to be used on 
fixed disks and does not normally support removable media. To use HPFS 
on a Zip disk you must first Lock the disk, then format it with OS/2's 
Format program and the /FS:HPFS switch. As soon as Iomega's driver 
detects that a Zip disk is HPFS formatted it locks the disk and it 
remains locked during the entire OS/2 session. The eject button on the 
unit is disabled while the disk is locked. The only way to change the 
disk is to shut down the system and reboot.

FAT formatted disks can be freely swapped during an OS/2 session with 
only one problem, apparently FixPak 17 'broke' the ability for OS/2 to 
store Extended Attributes (EA's) larger than 1k for files saved to the 
Zip disk.
