I have a pen drive problem that is really doing my head in. I have 2 pen drives, one is 8GB and the other is 16GB, and the problem I am getting is that I can copy up to 4GB of info to the drives with no problem, and the info is readable, but as soon as I go over 4GB, everything on the drives is trashed and unreadable. If I try to delete the info, I just get an error saying that the files are corrupt and can't be deleted. The only way to delete them is to format the drive. If this just happened on 1 drive, I would put it down to the the pen drive being faulty, but I have the same problem with both. I also have a 300GB external USB HDD, and have no problems at all with that. Any advice would be greatly appreciated Cheers
The drive is formatted using FAT32 which can only handle 4gb files.Changing it to NTFS is generally not recommended for flash drives due to the extra `wear and tear` it creates in terms of reads/writes.
Thanks for the quick reply, but I still have the same problem if I copy multiple smaller files over, everything is readable on the drives up to 4GB, but if I then add another small file that takes me over 4GB everything gets screwed up.
I think the comments above about the file size limit and the FAT32 file system are probably on the right track.
I have tried copying a 1.4GB file to my 32GB USB drive into several folders so that over 9GB of data has been copied to the 32GB drive without any problem, but, after deleting most of the 1.4GB files and then trying to copy a single 23GB file I get a message that the media is full and to insert new media.
There is sufficient free space on the drive, but I think I have exceeded the file size limit for the FAT32 file system. This may also be your problem.
