[ltp] CD-RW on T30 won't write: Input-output error

[James McKenzie]

Whil:

Try writing at 4x speed.  I think that the max speed is 8x on the stock 
CD-RW drive for the T30 if it is the same model as in the A22p.  I had 
to back down the drive speed in order to keep from creating coasters.  
Better media will prevent coasters, but there is no guarantee.
