is partitioned and formatted for Linux, most likely. Aside from that, its FW should not block its use in a PC. You should be aware though that PVR drives dont have data error correction, so dont store anything valuable on it.
Download and make a Linux Live CD to boot the PC with the drive connected to an internal SATA port (cant use USB adapter). Delete the partition, then you should be able to use Windows to repartition and format it.
It's weird that your BIOS doesn't see it. Make sure you plug in the PSU power connector.
I have recently removed a Seagate 250GB Sata hdd from a PVR that was discontinued from ExpressVu with the hopes of salvaging it as an external storage device. I downloaded Seatools for Windows to confirm the drive was still good and it is. However I cannot initialize the drive on my p.c. I have a SATA to USB kit with its own power supply and tried using that first. No luck. Every time I try to initialize the drive the error "Data error (cyclic redundancy check)" comes up. I then opened up my desktop system and hooked it up hoping that would work but no. Same problem. (I am running Windows 7 Ultra btw). I went into my system bios and it seems my bios doesn't recognize the Seagate drive for some reason. When I run Windows disk manager it finds it however.
Has anyone ever tried to recycle a hdd from a PVR and run into this problem before? Do I need to download a special program to format this drive so I can use it?
Thanks in advance!
