Description of problem:
Ripping with cdparanoia is very slow on my SCSI drives (much slower
than real time), and cdparanoia is spewing a lot of errors in the process.
It also claims that my SCSI drives are really ATAPI drives running
under SCSI emulation.
I will attach four files:
strace/console output for a PIONEER DVD-ROM DVD-303F (works, but is
strace/console output for a PLEXTOR CD-ROM PX-40TS (does not work at
all, claims that no extraction method was found).
Both produce lots of lines like
"Buffer I/O error on device srx, logical block yyy"
with x being the drive number and yyy a block number in the system log.
Both drives have worked fine as extraction drives back in FC1.
Both drives are connected to an Adaptec 2940UW controller.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Try to rip from a SCSI drive
Actual Results: Lots of errors on the console, errors in syslog,
ripping very slow
Expected Results: Fast ripping
