Can't see folders on Flash disk

I recently got a virus on my flash disk. Well, a whole bunch of viruses. I virus-scanned and removed them...at least most of them. But, now my flash disk is acting funny:

1. I can't open the flash disk by clicking on it. It gives me the "Open With" dialog.

2. This has happened before, so I know to right click and select Open. However, this doesn't work this time...I get the same "Open With" dialog.

3. I can't see any of my folders on the flash disk. I know all the files are still there, because the memory consumption is the same as it was before I got the virus.

This happened before...I was able to fix it by taking the flash disk to another computer, which allowed me to see the folders. However, the folder icon was a bit more transparent than the normal folder icon. Anyway, that time, I re-created the folders, and copied all the files into the new folders. I took everything off the flash disk and formatted it, put all my files back on, and it worked like magic.

BUT, this time, it's not working. I've taken the flash disk to a lot of different computers, and it doesn't work. I've tried to go to Tools...Options and select "Show hidden folders", but I get nothing. In fact, if I go back to the Tools...Options window, "Do not show hidden files and folders" is again selected.

I ran a "Fix Errors", but everything was fine.

I backed up everything on the flash disk. During that procedure, I could see all the folders (to select to be backed up). But, when I restored the backup (on my PC), I was still not able to see the folders.

That's about everything I've tried. Hopefully someone can help me.

Thanks so much.

 

First, merge this reg file to rerstore the default context items for drives:

Then use this tool to remove the partitions from the drive, repartition, and reformat:
