Disclaimer: I'm pretty new to macs, but would consider myself a competent user.
I have an WD 500gig My Book external hard drive that I use on both my macbook pro (running Mac OS X 10.4.11) and PC. I don't remember ever formatting it, it just worked on both as soon as I plugged it in.
A few days back, the hard drive accidentally unplugged from my mac (aka, I did not eject it). When I plugged it back in, the hard drive would not pop up on the desktop. I'm 99.9% sure that all the hardware is fine-- it still works on the PC, and lights and spins when I plug it in-- and when I go into the System Profiler, the USB says that my external hard drive is attached. (One forum said you can click and force it to manually mount the drive, but I can't figure out how to do that.) I also installed Disk Warrior, which recognizes the hard drive, but says "The directory cannot be rebuilt, the file system is unsupported." There are bullets under that that say " This disk is not a Macintosh disk; This disk does not appear on the desktop; This disk is 465.75GB in size."
Every similar problem I've read about (including this
one) turns out to be either hardware or fixable by Disk Warrior. Please help!
