Certainly; although the root cause of this should already be long fixed since
Haiku is probing for the actual end of the device.
This particular change should only prevent CDs with errors from being read (ie.
don't waste a complete cache line if just one block is corrupted). It may also
hide problems with an incorrect probe for the length of the CD, though.
I must admit that I still haven't found the time to actually test this change,
though; I have a CD that is problematic under Haiku (but not on Linux or
Windows), and I will test this change once I have found that one again :-)
Bye,
Axel.
