Cracking Open a Seagate 50 MB RLL drive

Seagate ST-250R

By Drew McBee

Here we have our Seagate ST-250R and old RLL HDD that sports a 50M unformatted and a 42M formatted capacity. I believe you would use an MFM controller for this. I actually used it in a 286 running IBM-DOS back in the day.

I did power it up and it seems to run properly. Nice to know that before I crack it open.
