From my personal collection has been used as a backup drive for my bbs. I installed a SCSI2SD board so the drive is set up as 4gb drive and can accommodate over 200 16mb partitions!
I have never had any issues with it. It does have some scratches and blemishes consistent with age. There is also a dent on the back corner.
