So my sister's girlfriend is a professional photographer. Her former consultant get her an SCSI 68-pin connected Sony StorMaster tape drive that backs up her 3 big NAS drives with all her work via EMC Retrospect. This was on a PowerMac G5 tower with an SCSI 68-pin card installed. She's moving and has tasked me with getting it all up and running again at her new place since she's fallen out with the old consultant (who did some weird, weird stuff with their network - why are there 3 switches for the NAS? Why does the Airport run through two of them? WTF?) and gotten an iMac 27" i7. Now, problem is, obviously that her i7 has no way of plugging into that SCSI tape drive. She's been using her G5 PURELY to run Retrospect which is a waste of space and energy. Plus she's moving to a much smaller space, so I really, really want to get it out of there. So here's the thing - I CANNOT find a 68-pin SCSI to USB adapter other than one by Ratoc, which apparently only lets the tape drive function in "mass storage mode" which doesn't really tell me if it will work with Retrospect or not. IS THERE ANOTHER SOLUTION to keep the current tape drive and plug it into the iMac? Please, please please help me out here guys! Thanks!
