This is a list of Seagate SCSI (FC,LVD,SE) drives. The currently available drives are marked with a blue o while non-current drives are marked with a red o .

Some of the older drives have an index into a table of raw drive geometries and suggested modified values for use on operating systems that can't autosize a disk (i.e. SUNOS and HP/UX).

The Seagate magic product number decoder:
The 1st digit after "ST" is the physical size (1=half height 3", 3=low profile 3", 4=full height 5", 5=low profile economy 3"). The last 2 digits are a Product Line and Subline denominator. The last digit will increment by 1 or 2 from year to year. The digits in the middle are the size of the drive (formatted for drives produced from 1996 on, unformatted for drives before 1996).
