The latest volume of the "Techno Club" sampler comes with
copy protection - my first audio CD of that kind.

Last time I had to deal with such crap was with protected
Apple ][ floppies more than ten years ago.

The lesson from that time was that interested parties still
were able to circumvent the measures, while making life
less comfortable.

In this particular case I tried the CD in the ATAPI
drive of a NT box - the drive seeks to death.

The cdrom drive in a 5000$ IBM Thinkpad under OS/2 had no 
troubles with it, even digital transfer was possible.

Under FreeBSD, in an old Pioneer DR-U12X SCSI drive,
I can enter it for the first time and do a TOC request
 
    marc@oranje$ cdcontrol info
    cdcontrol: no CD device name specified, defaulting to /dev/cd0c
    Starting track = 1, ending track = 15, TOC size = 4 bytes

and play it via "cdcontrol play" (thus analog transfer).
No luck with digital transfers yet.

It also seems that the CD-ROM driver can get confused.

One of the reasons seems to be the data track at 75:19.00,
which end 87:39.17 looks like lying outside the real CD.

Copy or not, I hate it, when I can't play my CDs reliable
on my computer - anyone has been nagged by similiar discs?

Marc
