Isn't it just the free space!!? thats being erased!!?
Yes. At least, one hopes. When did that feature get added to Disk Utility? I'd never noticed it before.
And obviously something went wrong with the process or it started very quickly then stalled, causing the calculation to break.
Question: Did it stall completely at that point (with the hours ticking up continuously and no disk access) or is it actually doing something and just the count is wrong?
If it appears stalled but the disk is active, one possibility is that there are bad sectors on the disk and the OS accessing them is causing the disk to run through its (usually slow) recovery process.
