Windows 7: Files mysteriously disappearing from external drive ???

Thanks, Vino. I removed Nod143 and all its helpers in registry, etc. I hope that was the problem

Important to note: AVG did not find this virus, nor did Avast

See if MSE will find any left-overs (run a 'full' scan after updating):

nod143.exe has hidden attributes.

Thanks, I am running MS Security Essentials now. Will let you know if it finds anything

PS: you are right about NOD, it is a very elusive virus. I had at least 7 entries in my registry.

HELP - Files keep disappearing from drive --- just now

I have the most vexing problem. I posted about this before but I have more news so I have started a new thread.

I have an external USB drive. For some reason EVERYTHING is being deleted from it except the directory structure. I have completely cleaned my machine and no viruses or worms exist. I am running Win 7 64 bit.

After losing everything on the drive, I added some files a few days ago and marked two of them as READ ONLY. Today while I was on a web site I went to print out a page to PDF. At that point I heard the drive spin up. I went to check the files and they were all gone... except the two I had marked READ ONLY!

I have two other drives hooked up to this computer via USB and both are perfectly fine.

Can anyone help me figure out what is going on? Is there anywhere in the EVENT VIEWER I can see if something caused those files to be deleted today?

Please help

I don't think you are removing the USB drive from your computer in a proper way. Let me know how you do it!!!!!!

Ok, I thought I would follow up for posterity. I found out what the problem was. USB port overload. I was running too many devices through a USB hub. That's what caused the files to disappear. Problem is, they weren't gone when I thought they were. If would have just rebooted they would have returned. But no, I panic'd when I couldn't get answers and mined the disk with recovery software, grabbed what I could get, then -- at th behest of Seagate support -- reformatted my drive. Oops. Data gone forever. Really sad. Had just never heard of USB hub overload and didn't ever think that could be a possibility. Lesson learned. Hope this saves someone some headaches some day.

I'm suffering from a similar problem to the original poster. I bought a Seagate external HD last week, and moved a load of stuff over to it to make room on my internal drive.

When I checked last night dozens of files had disappeared. Oddly, with me it's only the .exe files that have gone. There's not a single .exe file left on the drive, yet everything else is still there.

I've scanned with Malwarebytes, AVG and Avast and found nothing. I've tried Recuver, but that doesn't find any deleted files. I've plugged the external HD into a different USB port and rebooted, but the files are still missing.

I'm really at a loss as to what to do next, so any help or advice would be greatly appreciated. Many thanks.

PS I'm actually running Windows XP, but this was the most relevant thread I could find.
