Weird bug in the "swap" mode.
LBA[077399, 0x12e57], MSF[17:13:74], mode 2 Invalid mode: [e2]
SubHeader[1](IsInterleaved[00]), [2](ChannelNum[00]), [3](SubMode[00]), Form 1, [4](CodingInfo[00])
LBA[077400, 0x12e58], MSF[17:14:00], mode 2 Invalid mode: [c2]
SubHeader[1](IsInterleaved[00]), [2](ChannelNum[00]), [3](SubMode[00]), Form 1, [4](CodingInfo[00])
LBA[077401, 0x12e59], MSF[ff:13:8f], bad msf
[ERROR] Number of sector(s) where bad MSF: 1
Sector: 77401,
[ERROR] Number of sector(s) where mode is invalid: 2
Sector: 77399, 77400,
Total errors: 3
Total warnings: 0
But, in fact, "mode 2 Invalid mode: [e2]" is the sector 77400; "mode 2 Invalid mode: [c2]" is the sector 77401 and the "MSF[ff:13:8f], bad msf" is probably about the first sector of the lead-out.
