Hard disk failed and chkdsk?

I have a disk that mainly contains data files. My disk have bad sectors and some of the files cannot be moved to another disk (it will stuck when moving and never complete 100%), most files are still normal (can read/edit/move). My Macrium reflect software is unable to do a backup on that disk.
Western Digital Data LifeGuard Diagnostics failed, quick test did not complete, screenshot https://i.imgur.com/Xx7VXgu.png

I read that sometimes chkdsk /r can destroy hard disk and make it worse, and I am afraid to do any more things to it, I have some questions.

1. Should I do chkdsk /r first then save all the files to another new hard disk to replace the old hard disk?

2. Should I move all the files that are movable to a new hard disk (there will be some files that cannot be moved), then do chkdsk /r then move the files to a new hard disk?

3. Is moving or copying better? Is there some program that can auto skip the file that is stuck while move/copying? (so I do not need to stay by the PC to click next/skip when a file is stuck)

4. What is the the proper way to do chkdsk /r and is /r correct? Some say do it in DOS, some say do it in windows.

Thanks

If it has bad blocks they are dead and any file is gone. You need to get a test programming from the disk makers site to test the drive there free. Copy what files you can before running checksum running it from a cmd prompt is best. What said you have bad blocks?

The results you got with the WD test app are not good, and suspect the drive could fail completely at any time.

As to moving vs. copying, I always do the latter when I need to worry about losing the source. If the move fails, that could happen.

Is there a risk that if I switch off my PC now and I might not be able to access the hard disk again (not detected due to hard disk failure)? Should I power up my PC continuously until I have copied all the files to a new hard disk?

I was intending to switch off my PC to insert and connect a new 3.5inch internal hard disk for copying files to it and afraid that the old disk no longer works/detected if I switch off the power. I am thinking if I should just buy a usb external hard disk so I can just plug in and so that the pc power can be continuously switched on.

Possibly, yes. It's hard to say how high risk, but it's probably safer to leave it turned on.

Hi there

depending on the amount of data you could back it up to the Cloud via Ms's OneDrive application before attempting any repairs.

External USB drive is also OK -- shouldn't cause any problems when connecting to computer.

COPY though rather than MOVE. You can always delete afterwards.

If sectors are truly bad then chuck the HDD after doing your recovery. Often DATA on the HDD is far more valuable than the HDD itself.
Again though you should always have BACKUPS -- how many times to people emphasize this and STILL people don't do it.

Had you had backups then no probs whatsover - simply replace HDD and restore.

Anyway good to remember in future -- ALWAYS BACKUP OS AND IMPORTANT DATA.
