I'm seeing a problem with MC and secure ripping.
I ripped a CD with one drive, and MC says the CD rip was in secure mode, and there were no retries:
I'm with You - Red Hot Chili Peppers
>>> Drive D: TSSTcorpDVDWBD SH-B123L
Mode:ModeSecure Type:Auto Speed:Max
Track 4: Secure rip, no re-tries. [Ethiopia]
But the CD has an audible silent gap at 1 minute 50 seconds into the track.
I re-rip with another drive:
>>> Drive D: TSSTcorpCDDVDW SH-S203N
Mode:ModeSecure Type:Auto Speed:Max
Track 4: Secure rip, no re-tries. [Ethiopia]
and again MC says there were no retries. This time, there is no audible silent gap at 1:50. So, let's see if the two files are the same size at least:
$ ls -l "bad - 04 Ethiopia.flac" "04 Ethiopia.flac"
-rwxr-xr-x+ 1 MrC None 28280288 Sep 19 17:25 04 Ethiopia.flac
-rwxr-xr-x+ 1 MrC None 28280288 Sep 8 14:08 bad - 04 Ethiopia.flac
Yup, same size. Now let's look at those bytes:
$ cmp -l "bad - 04 Ethiopia.flac" "04 Ethiopia.flac"
137 60 (0x30) 67 (0x37)
13550716 44 (0x24) 54 (0x2c)
So, there is a small difference at the beginning of the file (no surprise), but midway into the track data, the difference of a single bit is causing the audible gap.
Let's test with flac:
$ flac -t bad\ -\ 04\ Ethiopia.flac
flac 1.2.1, Copyright (C) 2000,2001,2002,2003,2004,2005,2006,2007 Josh Coalson

bad - 04 Ethiopia.flac: testing, 46% complete
bad - 04 Ethiopia.flac: *** Got error code 2:FLAC__STREAM_DECODER_ERROR_STATUS_FRAME_CRC_MISMATCH
bad - 04 Ethiopia.flac: ERROR while decoding data
state = FLAC__STREAM_DECODER_READ_FRAME
Should this shake my confidence in MC's reporting of a secure rip with no retries? Or perhaps this was a memory error during the wav -> flac conversion?
Comments?
