    I'm trying to run disk first aid on a time machine disk. It's a 2 GB disk, with about 628 GB used.

    How long should it take to run "Checking multilinked files."?
    Would it run faster if it had more memory to play with? Currently it's using only 3.01 GB. Apparently fsck-hfs has a '-c' flag if run from the command line.
    Is there any way to safely abort the process?

    Checking Time Machine partitions can take a long time. Apple uses hard links to create the illusion of a huge drive and this is pretty much exclusive to Time Machine. I am quite sure that this is what causes the delay.

    BTW, running with "-c 8g" produces a memory footprint of 3.01g. So there are limits to the program's appetite.
