I bought this to use on my Vista Home Premium SP1 64 bit but the Seagate Manger when installing says it's for 32 Bit only. My question is, can I still use this on my 64 bit computer. I wish these manufacturers would say in Vista if it's for 32 or 64 bit or both. They just say vista, and having just moved to vista I'm learning the hard way. The part number of the drive is 9ZC2A3-500.
