I agree with Sminlal, the firmware Version can be extracted using DiskCheckUp, or HDTune.
I looked at your HDD, and don't see the firmware Version listed.
For IBM drives of that year 2000 vintage, they were listed similar to VA30B40K.
Don't know if I would purchase the IBM Deskstar from that era, since they had a bad record of crashing and a class action law suit, later called "DeathStars". I don't remember the exact "problem" sizes, but think they were less than 100 MB.
If you need an IDE drive, you can still find PATA drives, up to 500 GB, which are relatively inexpensive.
