I had mine lock up once and nothing would get it to come back to life except for a cold boot. I was running 1.03 at the time. If it was a hard disk cable problem then it shouldn't happen again. My players were sent off to empeg to have my 10Gb and 60Gb become a 40Gb and 30Gb to keep the warranty.

I'll keep an eye on it to see if the lock up occurs again.
