Exactly! Even with proper direct write configuration of the USB drive
, I still occasionally experience "Delayed Write Failed" errors. So,
my question is this: What is likely to happen to a FB DB when a write
fails? Will the DB be corrupted? Will it be recoverable? Or will
everything be fine, just data from the failed transaction missing?
