"Thanks for everyones help so far, I'm sorry to say I've tried everything now and no joy yet. I've just found this article
http://wdc.custhelp.com/cgi-bin/wdc....p?p_faqid=1787 and it looks like my Western Digital Studio Book is not bootable from a PowerPC which I am very unhappy about. Just spent £120 on a useless drive"
Important questions:
- Does your WD drive have a separate "CD partition" on it, containing some proprietary WD software, that includes a password?
- If so, do you have the password protection enabled?
A friend also bought a WD external -- I would not have recommended it, but he made an impulse purchase without consulting me. It, too, would not boot --- UNTIL I discovered that he had password-protected the drive using some proprietary software that comes bundled on the drive.
I was able to find a way to remove the password protection. After that, the drive booted normally (via USB with his aluminum 24" iMac).
I also got him to use CarbonCopyCloner. We were able to clone the internal drive, and (again, with password protection removed), verify the boot from the external.
Suggestion to original poster:
Take the problem WD drive to _another_ Mac, hook it up, just see if you can get it to mount on the destkop.
If you can do that, and if it has something called WD Tools (or some similar name) on it, go in there and disable the password (assuming that you may have had one entered).
Then, try rebooting via USB.
Suggestion to ANY reader of this post:
If you are using either SuperDuper or CarbonCopyCloner to clone your internal drive to an external, and you have never actually tried booting from your clone, it might be a good idea to try that, just to see if it will actually work for you in a "moment of extreme need". I believe that when running SuperDuper, there is an option that can be set that will automatically reboot from the clone when the backup is finished, just to be sure that it's "a good clone". Yes, this takes a bit more time, but gives you the peace of mind that you HAVE a "bootable clone" in the wings....
My own strategy (that has worked for me for years -- I have files from 1987 that are instantly accessible to me on this Mac):
I keep my most important data on a SEPARATE PARTITION other than my boot partition. Yes, that means there's another icon on my desktop (I currently have no less than SEVEN drive icons on the desktop, so what?) Because system files aren't involved, that "Main data" partition can be relatively small in size -- in my case, a 40gig partition, only a small fraction of that actually represents the data.
But -- I can use SuperDuper to do an incremental backup of that [exclusive] data partition only. I just did one reading this post -- elapsed time was about 12 seconds. Can you spare 12 seconds to backup your most important files?
