Is there another site from which to get the unlocker utility? Windows security definitely does not like the web site (not just a popup, but the whole browser window background goes red with warning text - never ran into that before) and warns of viruses and potential exposure of personal/sensitive data on my PC. When I press on, and get linked to the Brothersoft(?) site which actually has the download, the unlocker download yields a second warning that the file has been reported as unsafe. I hear ya saying it okay, but I don't visit sites that invoke such a violent reaction from Microsoft (yes, I know talking about Microsoft...) and my warm and fuzzies about this have gone cold. Call me chicken.

Anyway, I wouldn't mind having the unlocker utility but I think I'm going to go with more extreme measures. I did manage to recover the "missing" TIFF picture files via Easeus' Data Recovery Wizard program. However, I've run into a couple of other folders on the drive that are experiencing the same issue and these folders have had nothing to do with the actions that caused the original problem (or so it seems). It seems the file system is hosed and seems unrecoverable. So what I've decided to do is to copy everything off the drive and onto another drive and then reformat the offending drive. I think I'll only use this physical drive as an backup/archive low activity drive rather than one with frequent activities.

Thanks for all the suggestions.
