I have problem with a flashdrive: Samsung "MightyDrive" 4GB. Using chkdsk /f produced the following errors:
"Removing trailing folder entries from ..."
"Removing nonvalid long folder entry from ... "
"... is cross-linked on allocation unit ..."
"... invalid time stamp"

In addition, there were files with strange characters, which together were over 10GB while the flashdrive is only 4GB.
Having fixed the prblems with chkdsk, I again ran chkdsk and new problems were there. I can keep doing this and new problems keep popping up.
Therefore, I formatted the flashdrive and ran chkdsk. All problems were gone. I copied files from my harddrive to the flashdrive and again ran chkdsk. The problems were back.
I also ran chkdsk on the harddrive, but there were no problems with the harddrive.
I've also tried the above (formatting the flashdrive) for a second time, with the same result.
With chkdsk /r there don't seem to be any bad sectors.

Does anyone have an idea what the problem might be? (the flashsdrive is less than a year old) Thanks in advance!

Someone suggested it might be that file names might be too long.
Could this indeed be causing the problems?
How could I test if this is causing the problems (there are over 1000 files)?
