Unfortunately, I have a Samsung HM500JI which is an older Samsung model. Samsung HDD department was bought out by Seagate, so I can't use Samsung support. These drives haven't been put under the Seagate utility DOS software.
The Seagate software did detect a lot of errors, but wasn't allowed to repair them as the reason above.
With the cleanall diskpart and option 2 of disk check, the Windows install still had the same error, and had 0B of space left with a 455GB partition.
Is it time for a new drive? Or is there anything else I can do?
