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

[Thomas J Magliery PhD]

Andy, sorry this took me so long.  I did as you asked.  I get the 
following message upon running *either* version of the program:

:-( unable to READ DISK INFORMATION: Bad file descriptor
What does this mean?  Incidentally, I had a blank DVD+R in the drive. 
Is this what you wanted for this test?

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"
int main(int argc,char *argv[])
{ Scsi_Command cmd;
 unsigned char dinfo[32+4];
 int i,err;
   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");
}
