Hello fellow CD ripping enthusiasts!
I've encountered a peculiar problem with AccurateRip CD detection and was wondering if someone could explain the possible cause or better propose a solution: CDs aren't detected in AccurateRip on FireWire on a Mac.
I've got an external Macally 5.25" USB+FireWire enclosure (PHC-500BC, Initio INIC-1430 FireWire chipset), several IDE drives (Sony DW-Q120A, NEC NR-7800B and some others). On any Mac (both Intel and Apple Silicon) half of my CDs aren't detected in AR database when using FireWire connection, on USB those same CDs are fine.
E. g. a Paul Simon Anthology CD1 (9362-45408-2) is found in AR with USB. With FireWire it is not and track checksums also differ from AR's although there are no errors. At the same time an other discs (e. g. Pink Floyd Wish You Were Here 7243 8 29750 2 1) is found in AR on both USB and FireWire. If I use `dd` to transfer individual tracks (`dd if=/dev/disk4s1 of=track1fw`) it produces the same md5 sum on both FW and USB.
All of the drive functions (C2, cache) are detected identical on either connection. XLD on a Mac won't detect discs in AR database also. Furthermore there is no such problem with this enclosure on Windows: all of the CDs check fine in AR on both FW and USB.
I understand it might be some Mac hardware compatibility problem. Can a FireWire bridge cause different drive read offsets? I've tried to go over a hundred offsets to no avail. Apart from AR detection FireWire connection works just fine.
