Scanning for and repairing bad sectors

Good morning everyone,
I tried Tune Up Utilities to check external harddrive, but it crashed.
So am trying to check with a different program, loading Seatools right now.is it any good? Can someone recommend a good program for checking and repairing, please?
Answer #1
chkdsk x: /r from command prompt is all you need really, Bad sectors can’t be repaired however
as they’re a physical problem (damage to the platters from a faulty read/write head), Each HDD has a limited number
of spare sectors so they can be remapped with good ones, But generally speaking, An HDD with bad sectors
should not be trusted! Keeping it is just asking for trouble.
Answer #2
Hiren’s BootCD 10 > Hard Disk Tools > HDD Regenerator
There is also a HDD Regenerator Windows version..

Yep. Also, If your using Vista/Win7 you have to run command prompt as admin (type it in the search box on the start menu then right click
and pick “run as administrator”)

Ah ok thanks man.
Another stupid question, what does the r stand for?
Answer #7
/R Locates bad sectors and recovers readable information (implies /F)
