If you don't know of anything specifically wrong with the drive....and if it's just old....I wouldn't be concerned.Thanks Jay,
Ive just installed a new mobo and cpu and using the old Hard drive I had previously. Maybe im just paranoid the SATA cables are all new so I don't think there would be a problem with those. I just didn't want the old hard drive creating any issues at the cost of saving a few £'s as the previous mobo is dead wasn't sure of the problem so I think it'll be ok hopefully.
