Can a PCM be overflashed and cause damage? I'm guessing if it is damaged the car won't start right?

98 cars seem to be prone to this ... something to do w/a bad file being written to them... after which even w/a rewrite they can't be recovered.

There is an actual limit as to the number of times a PCM can be flashed... I believe it's in the hundreds if not thousands... however I've also heard that the OEM replacement (ones that were made afterwards for repairs) fail considerably earlier (fail to accept a reflash)....
