I have a Sony Vaio laptop. I bought it and it came with window 8. with a hard disk of 640 Gb. I had not even 25% of the hard disk occupied and started to give blue screens with error messages. It sent me a MESSAGE to change to window 8.1. I did not do it. Migrate to window 10 and keep working. Soon I started to give blue screens with error messages. Remove the hard DRIVE from the laptop and I made a DIAGNOSIS with a diagnostic program and it gives me a message of 30% damage.. I currently can not start the laptop. My question is Can you do a defragmentation in D.O.S systems to ISOLATE the damaged sector? For initial the laptopHi,

If you have access to the data on the hard drive, please backup your important data to a DIFFERENT hard drive as soon as possible, before doing any diagnostic or trying to fix further. May I know which utility did you use to diagnose?I was endorsing the data and managed to back up some of the data.
Diagnose it with two programs: the DISKINFO and the CENTINEL.
The question. I can defragment the hard drive in D.O.S to isolate the damaged sector and then boot the laptop and then work
