Strange problem with two drives.

post #1 of 2
Thread Starter 
Hi guys,

I have just copy and pasted the contents of one hard drive to another drive (copied from a WD 500gb blue to a WD 500gb black) and the drive that I pasted it to is showing about 30gb less used than the other?

I set them to show hidden file but there are non, any ideas what could cause this?

Could be a few things

  • Different file formats (unlikely)
  • MFT on the first drive is wrong (improperly allocating free space)
  • Different cylinder boundaries/drive 'geometry'
