Yes, using -s1   -s2 and warpmodes works just fine. Reads the very same disk 
perfectly. Reading the disk with parallel transfer several times shows the 
errors on different places ....

I am using one of these adapters which Protovision is selling. One end 
connects directly into the PC parallel port. Attached to it is a platine 
(board) which has a serial port and a port for the parallel cable. You surely 
know it.
That way the 1541 can be connected to the PC using the standard IEC cables and 
the parallel cable soldered to the drive.

This also allows me to test the parallel cable on the c64. Using several 
parallel copiers and nibblers has shown me that the parallel cables attached 
to (two different) drives are working fine. 

Also, if one of the wires would be broken on the cable, it should error all 
the way or just pass even unnoticed. Dunno how the routines there are 
programmed.

I will try to catch you on IRC and ask for a test procedure you like me to go 
through or sumthing. :)
