chkdsk C: /r vs. Clonezilla scan vs. SpinRite vs. Other

I used chkdsk c: /r, which made it possible for Clonezilla to work, and it appears to have fixed the problem.

Clonezilla has an option to check the SOURCE for errors, before you make the clone - but I don't see where it says what it does (any idea?)

Is there any benefit to using something like SpinRite, or an alternative program?

Here's why I'm asking:

chkdsk C: /x /r . . . /R Locates bad sectors and recovers readable information (implies /F, when /scan not specified).

In Clonezilla . . . It can check the drive for errors. Does it do chkdsk C: /x /r ? . . . QUESTION #1 OF 3:  What does it do?

He could've used recovery software like SpinRite to get the data from the damaged sector before running CHKDSK. When CHKDSK goes over a bad sector it does nothing to try to lift the bytes from that sector . . . https://superuser.com/questions/209606/how-safe-is-it-to-run-chkdsk-on-an-ssd

Spinrite was awesome.  But it's also completely ancient.  It's built for recovering data from failing magnetic drives.

 

Do you have a failing drive?

 

if not, chkdsk is perfectly adequate for fixing file system errors due to power losses, crashes etc.  You don't really need anything more advanced than that except due to hardware failure.  And in that event - a backup to restore from would be far more preferable anyway!

Re: chkdsk C: /r vs. Clonezilla scan vs. SpinRite vs. Other

I wasn't able to make a clone, and ruined my two clones, due to "bad sectors" on the source, c: . . . I learned how to use chkdsk c: /x /r to fix it . . . then determined a pre-clone check is chkntfs c: . . . I then wondered if Clonezilla's check of the source drive did chkdsk c: /r, and found out it did:

 

Clonezilla live Forum . . . Partclone, * WARNING: The disk has bad sectors. . . . https://sourceforge.net/p/clonezilla/discussion/Clonezilla_live/thread/c6e7c09b/

 

Pre-clone check on an SSD? . . . chkntfs c: - Clonezilla live . . . yes, this is correct . . . https://sourceforge.net/p/clonezilla/discussion/Clonezilla_live/thread/37c49983/

 

Are these the same? . . . -fsck-y . . . and . . . chkdsk c: /r . . . Clonezilla live . . . "-fsck-y" actually runs ntfsfix from the pacakge ntfs-3g on GNU/Linux, while "chkdsk c: /r" is on MS Windows. They are different . . . if you select "-fsck-y", then Clonezilla determines the correct program to use, depending on the OS (Linux or Windows) . . . https://sourceforge.net/p/clonezilla/discussion/Clonezilla_live/thread/8f0f85bb/
