Here is a working 80-pin 73GB SCSI hard drive made by Seagate for Silicon Graphics. I pulled it from a RAID array in a standard full tower case that ran Windows XP. It is a low profile Ultra160 LVD/SE drive with four 3.5" platters spinning at 10,000 RPM with a 4MB buffer.
I pulled it from a RAID array in a standard full tower case that ran Windows XP. .I low level formatted and then tested this drive successfully under Windows 7 with an Adaptec 29320 SCSI host adapter. It makes normal sounds for this model.
Buyer will receive the exact drive and 5.25" bay adapter pictured here, but nothing else. It will come unpartitioned and unformatted.I offer a 30 day return privilege and free ground shipping to any U.S. zip code.
