Re: Disk Failure

["Dare" <oludare@xxxxxxxxxxxxx>]

If that's the case Andy and you're saying that only hardware that came out
with OS400 V4R4 have this capability.  My system was purchased in the early
to mid stages of OS400 V3.  Not to question your claim but I'm just trying
to fully understand the technology and its foundamentals.

Thanks,

Dare
