WD My Book suddenly stopped responding

[theGAPkid]

I have had a Western Digital My Book (Essential Edition) hooked up to my macbook (albeit on and off) for over 5 months. However, I also had a partitioned section solely for my PC. This worked fine for ages. Until the other day, my mac just stopped recognizing it. My windows PC still shows up the "windows" partition formatted FAT32??? if thats correct.

But the Mac partitioned sectors, formatted as Mac OS Extended (Journaled) are not picked up by my mac any more. Proper strange! It worked flawlessly for ages.

Thing is, Im reluctant to send it back to play.com (where I purchased it) cos they say they check each item, and technically, it does work, just not on my mac :S

Help?

Ta!

your first problem!

I just had this problem and it turned out that my logic board needed to be replaced. Thank goodness for applecare.

Before reaching this conclusion, however, test your Mac with another firewire drive or another mac booted into target disk mode and see if it comes up. The other possible problem, if you are using USB for your PC and firewire for your Mac, is that the firewire chip inside the hard drive enclosure is dead. So if you can reliably get other firewire drives to mount, it is likely the firewire chip on the drive, but if either others are intermittent or do not mount, it may that you need a logic board replacement.
