Re: plextor px-708uf: cannot get disk type

[Thomas J Magliery PhD]

Andy, what that last error meant is that I was specifying the device the 
wrong way (it is /dev/scd0 for me).  Anyway, here is the actual result:

Version with dinfo[32+4]
==============
[EMAIL PROTECTED] dvd+rw-tools-5.16.4.8.5]$ ./test /dev/scd0
:-( unable to READ DISK INFORMATION: Input/output error
==============
Version with dinfo[32]
==============
[EMAIL PROTECTED] dvd+rw-tools-5.16.4.8.5]$ ./test2 /dev/scd0
00 22 00 01 01 01 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 23 05 40 
00 00 00 00 00 00 00 00
==============

What does *this* mean?
Thanks,
Tom

Thomas! Could you run attached program with your /dev/dvd as argument?
Then remove +4 from dinfo declaration, recompile and re-run. To compile
save it in dvd+rw-tools source catalog and compile with g++. A.
8<--------8<--------8<--------8<--------8<--------8<--------8<--------
#include "transport.hxx"

   cmd.associate(argv[1]);
   cmd[0] = 0x51;
   cmd[8] = sizeof(dinfo);
   cmd[9] = 0;
   if (err=cmd.transport (READ,dinfo,sizeof(dinfo)))
       sperror ("READ DISK INFORMATION",err);
   else
       for(i=0;i<sizeof(dinfo);i++) printf("%02x ",dinfo[i]);
   printf("\n");
