I'm trying to copy/move files to an external 1 TB hard drive with about 50 GB remaining space. I receive a "no space left on disk" when I try.
I've moved files off and retried, but still get the same message. Disk Usage Analyzer, Properties, and freeware Treesize all report available hard drive space of about 50 GB.
df -i (50 GB available) and
df -k, with the latter reporting only 1% of inode usage.
I've been able to save files from Firefox to the drive also. I can't even rename files without getting the message. Yesterday in the midst of trying to figure this out I tried to move 4 files to the drive and got the message. Today, I found them on the drive. What's up with that? (That's the only time that has happened to my knowledge.)
Is this an Ubuntu problem? or is my hard drive just about to fail because of something like a controller problem?
