“If there’s corrupt media is there a fast way to determine where?”
check all of your OMFI directories for any files that may have a + sign at the beginning of the file name.
If so, you can try what I’ve had success with in the past:
copy those files to a temp drive if possible & delete them from the original drive.
on the temp drive you copied to, remove the + sign from files & save.
move those files back to the original drive & chances are you should be good to go.
good luck,
Bill
