I have an external hard drive that I switch between my computer and router(for NAS). I've had this setup for over a year and its been working fine. Lately files have been replaced with folders of the same name. When i click on them it says "file directory is not valid" Some of them turn back to normal after awhile, but others stay the same. Anyone know what could be causing this?
filesystem is NTFS
Movie folder has about 500 files
Music has about 5000 files
Are these too many files in one directory? (I thought the limits were supposed to be insanely high for ntfs)
I'm gonna try to move everything to another drive and reformat but I'm not sure if that will fix it.

I switched my antivirus to avg at the time this all started but correlation doesn't mean causation, I think its something else but I don't know what. (I switched back to my former antivirus just to be safe, plus I like it better.)
 
If the file system was working initially, it is not the problem. Fat32 is an old file system and will impose a 4 GB file size limit which may not even be workable, depending on what the OP is storing.

Performing a scan disk may reveal issues with the current format or file table structure which can be fixed, or it may take reformatting the drive.

Agreed on both counts, what I was told is that, it's firmware issue, this solution was given as a work around. As it has been quite sometime since he had this issue you try checking with your NAS manufacture to see if there any firmware updates for it.

just to give more info for future reference. That link was really insightful, Im using a cisco e4200 router. It would appear that this is a problem with the e4200 an 4500 routers rather than the hard drives, Fat32 won't work for me I need NTFS for my files. I'm guessing the file system is bad because of this so I'm gonna reformat. I'm just about done backing up all my good data (via usb so slow...) Im gonna delete the problem files then maybe try to restore them with recuva or another program. After that I'll do a quick format. I narrowed the problem down to two changes I made around the time this started happening. I enabled the media server option on the router and mapped the network drive on windows. Based on that discussion I believe the problem was the media server running, changing file attributes, confusing windows. I will attempt to set it up the way I had it previously with media server disabled. I'll update this when I get a chance to mess around with it next week.

Update 2/28/14
I set it up the way I had originally with the "media server" option disabled and have had no problems. I also mapped the network drive on windows again and it caused no problems as expected. It seems the problem was with the Twonky media server service on the cisco e4200 and 4500 routers.
