I have come into possession of a group of Seagate ST33000650ss 3TB HDDs, The stickers are labeled Seagate and have firmware revision XRR2. Does anyone know if this is a vendor-specific drive(HP, Dell, IBM)? Seagate has no newer firmware for the drive. I'm trying to install it into a Dell but when I do it makes this incessant chirp/knock, regardless of whatever controller/cabling combination I use. The drives also pass all diagnostics(2 drives failed) that I've tried and when I run them the noises stop until the diagnostic finishes, and then they return. I'm beginning to think that these drives won't work in a Dell. If so, is there a way to re-flash the firmware for Dell? Inquiring minds want to know!
