I was trying to see if I could rescue anything off of a cd-r which shows 
up as blank when I attempt to read it. It supposedly has data on it and 
I can see the telltale color difference that implies that it was in fact 
written to.

I tried ddrescue-

/ddrescue  -b2048 /dev/sr0 traincdimage  traincdlogfile/

Press Ctrl-C to interrupt
Initial status (read from logfile)
rescued:         0 B,  errsize:       0 B,  errors:       0
Current status
rescued:         0 B,  errsize:   3179 MB,  current rate:        0 B/s
    ipos:     2148 MB,   errors:       1,    average rate:        0 B/s
    opos:     2148 MB,     time from last successful read:    54.1 m
Finished /

This appears to be a complete fail.
Any comments? Running Mint 12.
