The oldest drive you have wiped with ShredOS/nwipe

[PartialVolume]

1995 vintage - Seagate ST31200N - 1 Gbyte

I'll start this off with a drive that was first released when Window 95 was debuted. A Seagate ST31200N, a 1Gbyte drive, 3.5" format with a 68 pin SCSI connector, not from a PC but from a Sun sparc station. It's specification says it can achieve a blistering 3MBytes/sec sustained and ShredOS confirms that. Still, it may not be fast but 27 years later it's still working and ShredOS wiped it using the wipe method. "HMG IS5" (God save the Queen).

I just spotted a ST31200N being sold on Ebay for £377 would you believe.

-Maximum Average 3.1 MBytes/sec 2.4 MBytes/sec

To wipe this drive I used a 32 bit Pentium 4 based system but added a PCI LSILogic SYM53C875 SCSI adapter. These drives have a 68pin SCSI connector so you need a SCSI adapter to make them work in a modern PC (P4 .. modern.. lol). Because you can daisy chain these drives you need to make sure the drive is appropriately terminated either on the drive itself using the TE jumper on J2 or using a external SCSI terminator.

LSI Logic SYM53C875 SCSI adapter, circa 1998.
