I get the above message when trying to copy my flashdrive to another flashdrive or a computer. It just started happening over the past 2 weeks. Prior to that, I could do it no problem. Is there a size limitation to copying a folder to another destination on a flashdrive? I now have over 2 GB of material to copy.
The only limitation for flash drives (other then their capacity) is that they are FAT32 and limited to a maximum file size of 4 GB unless formatted to NTFS.
It looks as if it's having a problem reading the data, hence it can't copy it.
Make sure to always use the safely remove option, otherwise they can get corupted.
