What does the verify do more specifically?

Hello Piriform team, I kind of get that the verify checks the hard drive for problems if I am right? Is that all it does? I was just curious. Defraggler is coming along! Nice job guys!

From the looks of it, looks like its doing a chkdsk on the drive (ie. checking it for drive errors)

Seems like it does not fix problems. Running chkdsk right after verifying still turns up errors.

...that will probably be because you can't correct errors on the boot drive (Windows volume)

when windows is running.

 

If you try "chkdsk -F" on your boot drive, Windows will not let you do it directly,

but complain...

 

 

Chkdsk cannot run because the volume is in use by

 

process. Would you like to schedule this volume

 

checked the next time the system restarts? (Y/N)

 

 

No doubt Defraggler can't do this either, for obvious reasons.

 

Normally, you should have a "clean" disk (if your machine hasn't been crashing

and you shut it down properly, so errors in the filing system should be fairly

rare. So using Defraggler to effect a quick check is convenient. If Defraggler

reports errors, then run chkdsk with the -F option and type Y to schedule

a chkdsk -F on startup, then reboot and wait. It shouldn't take more than a

few minutes to fix things up, mind you, chkdsk isn't perfect !

Actually I tried it on my D drive (2nd partition) with the /f/v/x switches. After using defragger to verify, then run chkdsk d: /f/v/x, chkdsk says it fixed minor errors. I then run chkdsk again and it says there is no error.

chkdsk can be a bit goofy in my opinion because sometimes when running a read-only (non-repairing) scan it will find something on my system, then running it again and it finds nothing wrong. Which is why I rarely if ever run chkdsk anymore, and instead only occasionally use it to remove old indexes with the /V option.
