Question: How do I turn my hard disk drive to its state when I first brought it. It has 250 gb unallocated space. But now, because of constant partitioning and experimenting. It has gained lots of unallocated space which cannot be brought back to be a whole unallocated space. What can I do, Ive already tried doing it while installing an OS, and inside drive manager but still no luck.
Answer: You can change the partitioning on the drive, but if you want to get it 1:1 back to factory state you will need to do a low level format. Most drive manufacturers make this tool easily accessible on their website.
Note that it is possible to brick drives depending on how you do the low level format.
