Are you sure about it being the first partition? Per default from
Iomega the disks come with the partition as #4...
When I try mounting a DOS disk (with a parallell ZIP) as /dev/sda1
(it is partition #4) I get:
mount: /dev/sda1 is not a valid block device
Trying the entire disk (/dev/sda) I get:
mount: wrong fs type, bad option, bad superblock on /dev/sda,
or too many mounted file systems
In your mount command above I assume -f to be a typo, it should be -t.
Have you tried 'mount -t msdos /dev/hdb4 /mnt' ?

There also seems to a bit of trouble with the disk geometry;
from http://www.torque.net/zip-ide.html:
"The IDE drive returns a geometry of 512 cylinders, 12 heads and 32 sectors
per track. The SCSI (and parallel) drives use a geometry of 96 cylinders,
64 heads and 32 sectors per track. The partition tables on Iomega formatted
media assume the SCSI geometry. While Linux appears to be able to read the
SCSI geometry disks on the IDE drive, you may wish to tell fdisk the
96/64/32 geometry numbers before altering the partition table on the
IDE drive."
