Repairs to defragmenting?

You asked a similar question a few days ago.

This question is even less clear than the first...

What goes in reverse?
What makes you think something is going in reverse?
What do you mean by goes in reverse?
What application (programme) are you using to defraggle?
What faults are being added?
What makes you think faults are being added?
How often are you running your defraggler?

Are you aware that Defragmentation has nothing to do with faults?

Defragmentation just tidies up the disk structure and makes files that have been fragmented (pieces not joined together) contiguous (joined together).

Defragmentation is the sort of housekeeping activity that should be done relatively infrequently - once a year perhaps.

Your defragmentation programme may discover - and avoid - bad blocks on the disk surface - is this what you mean by faults? If so you have bad blocks on your disk.

Are you using Piriform's Defraggler utility?
