I use almost exclusively Seagate drives, and am very pleased with the way they perform.
However, there are issues about your existing system regarding whether it can handle the whole capacity of the drive, whether you have the correct cable, etc, etc. Post again or search the threads for more details.
I don't know if you've put another post, or searched the forum's on this, but my BIOS will only recognise a 32gb drive max. My 60Gb Seagate drive has a limiter as one of the jumper settings, which limit's its reported size to 32gb. The Seagate installation software will put some software onto your computer if it needs it, and you should then be able to use the full capacity in Windows.
