I have seen this prob. described before on other lists, and the standard response goes something like this: There was a widespread problem with the Quantumn drives that Apple was using, caused by the internal lubricants becoming too viscous in humid environments and causeing hard drive failure. The fix involved installing a new PROM that activated the drive and heads every few minutes to keep the vicosity down (does this sound like a kludge to you too?). This may or may not be the cause of what you are describing. -Reed
