I have a hard drive that I'm almost positive is an old DVR drive. I put it in my computer and, while Windows didn't recognize it, it could be found using Seatools from Seagate. I did both a short and a long diagnostics test and it passed both. I'm now trying to figure out which DVR it came from. We've had numerous brands come through the house over the years: Sony, Toshiba, Tivo, etc... So how do I find out which DVR this hard drive came from? (I can't use dos commands like 'cd..' or '/dir', can I, since I'm booting off a CD?) Thanks in advance.
