My dad has a computer that is just trashed but the hard drive is still good. I want to wipe the Hard Drive clean of all it's current files though so I can use it as a whole new Hard Drive. How would I do this if the rest of the computer is trashed though???
BTW by "trashed" I mean it needs important parts and I want to erase the drive before I replace them those parts.
You will need another HDD to backup the files. Or put the drive in a running PC and partition the drive and load windows on the empty partition.
When you load windows, at the beginning there are options to delete the partition or partitions on the drive, make a "new" partition and format it then load windows on the newly created & formatted partition. That's the easiest & simplest way to do it.
For now I Would pick up and IDE r Sata to USB encloser. They run about 20 on new egg. I would put his old drive in it and see if he wants any of his data saved. They also make cable kits if you just want to do this once then format or reuse the drive. New mb all went to Sata drives there no IDE connection on newer mb.
