I have a truncated decrypted file, the original recording was an hour long, the time line shows an hour, but the playback terminates at 10 minutes and the file is only 300MB. Unfortunately this is on HDR1 which is still running unencrypt, the unencrypt log doesn't seem to be working, and undelete isn't working because the disk is nearly full.
Perhaps it's time I ditched unencrypt in favour of Auto-decrypt. Actually, it's time I commissioned HDR4 to take over daily duty from HDR1.
