Just thought I'd note that this problem still occurs with version 2.02.253

That's good news. Do you need any more from me? Mike

Good thought, Richard. But it still fails in the same way after chkdsk. Mike

Hi, I have recently started using Defraggler v2.00.230. Previous versions have been fine. On running "normal"/full defrag: it reaches 88%-90% then the Microsoft error dialog pops up: "Defrgaggler has encountered a problem and needs to close ..." Reading other posts, I have done the following: * Removed all but the most recent system restore point. * Run CCleaner (cleaning disk and registry) * Selected all files in list of fragmented files then choose "Defrag Checked". This works OK * Run Quick defrag. This works OK (and reports 0% fragmentation). After all of the obove, running full defrag again crashes as described above. Mike
