Fastfill goes into an infinite loop

[Mohaine]

A script I have used many, many times, decided to go into an infinite loop today, halting the defrag.

My script has:

  FileSelect
    ImportListFromBootOptimize()
  FileActions
    Defragment(Fast)
    FastFill(WithShuffling)
    AddGap(UntilPercentageOfVolumeMultiple(1))
  FileEnd

In my debug log, I see:

     Starting FileActions.
11:04:32     Defragment
11:04:32     FastFill

11:04:38         Trying to move away the item above the gap.
11:04:38           The end of the gap is above the end of the zone.

which then goes on for ever and ever until I kill MyDefrag (v4.1.2).

Taking off the "WithShuffling" option from the FastFill allowed the defrag to proceed.

4.1.2 had problem with the WithShuffling option, usually marking all files behind gaps as unmovable.
Try it with 4.2.0.

4.1.2 had problem with the WithShuffling option, usually marking all files behind gaps as unmovable.
Try it with 4.2.0.

Thanks, I'll give it a try.

I've got a similar problem using MyDefrag v4.2.0.Beta.

MyDefrag goes into an infinite loop - until killed. The extract from the debuglog is :-

11:30:41         I want to move 6 clusters at offset=2439 of item 'C:\System Volume

I've got a similar problem using MyDefrag v4.2.0.Beta.

Thanks for posting the logfile, I appreciate it. I have found the problem - something I overlooked - and it will be fixed in the next release.
