When I try to copy a 10 GB file to my 100 GB external hard drive - I get a "no space left on device" error after
4GB's have been copied (I've heard of this limit before - not sure if it's a device/partition limit or what).
There's plenty of free space (50 GB left).
Should I reformat the device. Why am I getting this problem and what do I need to do to be able
to copy the 10GB file.
