According to the documentation the drive is supposed to give an estimate
of how long the secure erase function will take to execute.
Before I started the function within Partition Magic (PM), PM told me it
would take 2 minutes. But when I actually hit the Execute button, the
completed dialog box popped up almost immediately. I was suspicious.
That is to say, I suspected that the drive had not actually finished but
only returned control to PM while it executed its internal erase
function. It took maybe a minute to find a terminal in PM and run
hexedit to check some sectors for zeros which seemed to confirm that the
internal erase process was successful.
The article also says to make sure the drive has time to complete the
erase process or else the drive could be left in an unstable state (ie
bricked).
So probably best to wait the duration suggested by the drive.
