Peter,
Thanks for suggesting Disk Utility. I didn't know it existed, but found it and ran it. I checked 'Verify Disk' and it "Found 335234 orphaned clusters, 25174 files, 6428792 KiB free (803599 clusters)" And, then responded (in Red) "Error: This disk needs to be repaired. Click Repair Disk."
After I checked "Repair Disk" it responded: "Volume repair complete. Updating boot support partitions for the volume as required."
After then checking the flash drive the 'lost' folder and files are still not present.
I've been looking on the WEB for 'recovery programs' for MAC. I'd just as soon find a 'free' application, but would consider purchasing a program if it would work. What do you know about these 'recovery programs':

Have you had any experience using any of them? There are many more out there including ones that will 'scan' your flash drive ('free') and tell you what files it can recover, then you have to purchase the full program (~$99) to actually recover them. Two of these programs are listed below:

I had even converted 7 of the original '.pages' files to '.pdf' files to eMail some friends in the universal '.pdf' format on Nov. 28th. The '.pdf' files were saved back to the original folder on the flash drive. They, also, cannot be found anywhere!!?? đ
I can re-build the files (~150-200 photo pages from vacation trip back in May), but there were many comments and some special research (maps, etc.) I had included that I would probably not be able to duplicate exactly. Luckily the '.jpg' photos from our trip are still present on the flash drive and also on the camera's memory stick - THANK GOODNESS! However, now I am hoping that one of the recovery programs listed above might solve my problem.
Again, thanks for your help, but I'm not THERE yet! đ
