my dad had a 15gb hdd sent to him from gateway when he thought his computer was "broken." since he had no use for it, i took it and installed it in my pc recently. before doing so, i read up on partitioning with fdisk and formatting and such, but when i booted up after installing it, my computer already recognized it as the F drive and it already had a windows folder and several other files on it. i assumed that it was already formatted by gateway before they shipped it so i just deleted the files on it and made a folder to store my music files. but now my computer runs extremely slow and i dont know why. can anyone please tell me what the problem could be? was i correct in assuming that the drive was already partitioned and formattted? thanks.
