My hard drive on my machine failed. I bought a new WD caviar 120 gig hard drive for my machine but failed to realize one thing. My HP did not come with the original win me disk but rather a recovery disk. These disks attempt to reinstall win me but instead of formatting for 120 gigs, it formats to 49 gigs. Will I be able to fix this after the fact when I use my win xp upgrade disk? Also the disk that came with the drive won't boot. Any advice would be great.
