OnePlus 5 review
My computer is home built. I have an Areca Raid controller with two Partitions (4- SSDs, and 4- 500 Gb Velociraptors). I also use an OCZ 256 GB RevoDrive 2X3, and two other 1 Tb drives. One of the 1 Tb drives, a WD, was from a previous computer that had crashed. Since it had all my old data I installed it to transfer the data. It installed as Drive 0. On MS Drive Manager it is listed as a Healthy, (system active,primary partition). I use a UK based cloning/ backup utility called HyperOs SuperGeek to clone and backup. In the HyperOs utility this drive is used for Partitions 1 & 2.
The problem I have is that once my data was transferred I wanted to remove the drive or utilize it. On removal I am not able to boot from the other partitions. I tried to format it so that I could use the drive for a clone OS, Windows refused to format it. I tried to delete the files in windows explorer, security prevented it. When I painstakingly took ownership of the directories and changed permissions to full control and deleted all the files on the drive, I found that the properties still showed about 135 Gb of data on the drive, and with win7 on top it makes the drive too slow to operate Adobe Premier at all. So it appears that I now have a drive with 135 Gb of hidden data on it that I cannot remove or format.
When you use a standard format the first 255 bytes are not erases, and that is the problem.
The name of the hard drive is western Digital, do a search for the hard drive and 'low level format'
I attach the Low Level format program.
Caution -- This is non- reversible. Make sure you select the correct drive to format
