Disk warrior external HDD light went off
I'm using DiskWarrior to do an external hard drive rebuild to save the files, if possible. Hard drive does not show up on the desktop, which had been viewable as a USB device on system profiler. During the rebuild, the light on the Seagate external HDD went off and is no longer viewable from the system profiler as a USB device. Should I cancel the rebuild? And should I try disk arbitrator to "stabilize" the disk and run disk warrior again?
