Cpu ... ... or it could just be a lone alpha particle hitting the bit in one of those places. Could also be a software error. A stray pointer in the kernel, being used to set a flag, and happening to point into a buffer for that disk block. Until it gets reproducible - or reproduces itself ... no way to tell. MfG Kai
