Corruption comes from inadequate memory (and, for a while, a bad RAM chip) and pushing it to the limit... then when something "squirrely" happens, having to go through checking and repairing the catalog files, etc. It all seems to leave its share of scars... Nothing that throwing a few handfuls of money under the hood wouldn't fix... The worst that has happened with PICT format is doctoring a line strip or two... A JPG file sometimes fails to be recoverable at all with whatever program I attempt to resussitate it with... I live with it; I use jaz and external SCISI drives both for backup...
