Anyways, I'll let you guys know > where the conversation w/ WDC leads to. WD said to me I can send them the disk, but didn't accept, that this is a firmware bug. Today I got a brandnew WD20EARS (2TB) and it is the same. After about an 1/2 hr. I had 12 cycles with an _un_formatted disk. I cannot accept, that it should be a warranty issue, because this reduces the lifetime _after_ the warranty and increases the possibility to loose data, at least for those who don't use a raid. I would be happy to have a native linux utility to change this.
