Hints/Comments:

• When I read the audio tracks at full speed (set 0 in the settings window), it happens that they have small errors, which sounds like when a CD player is jumping a bit. I can hear it only with really good audio equipment. Since I discovered those errors, I read audio tracks with single speed only. Perhaps it's just a subjective feeling, but the tracks now seem to be OK.
• Sometimes AFS causes problems on both hard disks -- it waits for 4-8 seconds without doing anything, my tasks are hold for that time, and after that, everything works again. I didn't have these pauses when I was using FFS -- but AFS is far faster...

No SCSI hangups. 50 CDs written, 40 successful. The 10 coasters resulted in either a frozen system or in strange error messages:

• I was clicking in other windows when writing -- the system froze and I had to reboot (I am using a 16 bit deep workbench screen --- perhaps that's the reason).
• Error messages like "Medium Error 2, Illegal request" (sorry, I can't remember the exact texts) happened. My CD writer sends these error codes to MakeCD and then it refuses to finish or repair the CD-R. The strange thing is: if I don't change anything (I just insert another CD-R), it writes this CD-R without any problems. I tried 6 or 7 different CD-R types, e.g. TDK, FUJI, KOCH, even nonames, but it seems to me that it makes no difference.
• On the other hand, I never had errors like buffer overflow or underrun, even if I write straight from a HDD in MS-DOS format, from my SCSI HDD or from my AT HDD to the CD writer. Sometimes, when I try to write directory trees that contain a few thousand very small files, I have to increase the buffer size from 8.000 KB to 24.000 KB to avoid getting a buffer underrun.
• I tried to remove all my Commodities (MCP, NewMode, MagicMenu and others), but nothing changed.
