Some time ago I had some problems with my Mac drive, so I went to the recovery partition and used Disk Utility to check for problems. It reported a huge discrepancy between the journaled free blocks and the actual free blocks, in the case of gigabytes.
I was wondering what may have caused this problem, and I remembered deleting a huge hierarchy of folders using
rm -rf, and since this command is almost instantaneous, I thought it may have caused this problem.
Does this make any sense? Should I avoid using this command on OS X with a Journaled drive?
