Thanks, I'll keep that in mind. Installing the two games again and will let defraggler have a go after that... I'll keep you informed.

It was a NTFS partition, formatted it anyway. It was not that big a deal, only just two games I lost and a couple of movies. The only strange thing is that it happened after I stopped defraggler after appr. 36% I like(d) defraggler I now just hesitate to use it....

Well... I guess it's time to format... When trying to chkdsk I get this message: Cannot run chkdsk -'CHKDSK is not available for RAW drives' Is it possible that defraggler caused this? I used it many times without a problem, this would be a first.

Hi Richard, thanks for the answer, will try that as soon as I get home. What does the /r do? Cheers, Marcel

Hi all, strange problem and hopefully someone has a solution... Yesterday I analyzed a hard drive and set it to defrag. After a while I stopped it (took to long and didn't want the computer on all night )just to resume it today. But to my horror the disk appears to be unaccessible.... explorer says local disk.... wtf? Error message in defraggler: the volume does not contain a recognized file system According to defraggler the disk is also totally full, which it was not at the time of the analyze/partly defrag. Please don't tell me I need to format the drive.... Any suggestions?
