External partitions disappeared.
I've been operating in a Macbook Pro 2.16 Ghz for about six months now. I have been using an USB external drive from Western Digital with 500GB space with no problems. In it, there's a partition in GUID filesystem from where I sometimes boot Tiger (besides a Time Machine backup partition).
I had no problem using this drive until now, when it stopped showing up in the desktop, finder, or anywhere else, even though I can see it'slight blinking and I can hear it working. Besides that, it crashes my disk utility, which is what I find the strangest, so I can't even repair it (this is, if there's something wrong with it). All this booting from the internal disk, where Leopard is installed.
So, out of despair, and because I thought there was something wrong with Leopard, I installed Tiger back on the internal drive, and the same thing happened.
To make sure it was not a problem in my hard drive, I decided to boot from it (where Tiger is installed as well) and it went great. But still I can't do much with the disk utility. Sometimes it crashes, and sometimes it gets stuck on a cycle I will now describe: I verified my external HDD and the Time Machine Backup Partition had some errors, which I immediately corrected. The thing is, after repairing, is checks the partition again, finds the same problems, and starts repairing again, never getting out of this cycle.
Other than that, my internal drive has a 15 GB windows XP partition, made with boot camp. Don't know if it is relevant but it's never too much to detail the situation.
Thanks in advance for your time.
