Unless the parallel transfer with the drive doesn't work reliable, I don't 
want to blame JD or SJD for special behaviour and therefore sticked to 
standard ROM for my tests.

Infact with SJD I have noticed several problems that are all on the behalf of 
SJD though. E.g.

# cbmctrl status 8
............................................
# cbmctrl dir 8
cbmctrl: dir: No such device


Since here it doesn't even respond to standard IO commands correctly I wonder 
how at all it works out :) ... will check closer whenever I get my JD128 
back.

Plain JD works rather well, just doesn't seem reliable. Actually, as I noted 
on a previous mail, JD+XMP-Cable seems slightly faster than plain 
ROM+XMP-Cable on SERIAL (1 and2) transfers.
Trying JD+XMP with parallel modes caused the same type of error behaviour I 
used to have. Enabling -w warp mode completely bugs out. error 23 all over 
the place and no sector is transferred ok.

Didn't take the time to check with all other serial modes yet.
Whenever I feel happy and my ordinary (Warp&Parallel) transfers works, I may 
start to dig around why the stuff doesn't work with SJD especially.

Joe, regarding my previous posts, is there anything else I could try, or have 
you heard of similar problems before ?
I am pretty sure I tried about anything possible, without even disturbing the 
errors or influencing the transfer at all :(
Even under heavy system load the transfer goes smooth for quite a few tracks, 
bugs out, continues for some tracks, bugs out ... etc.
It does the whole process slower though. The errors come up on the same disk 
on completely random locations, cables are tripple checked and everything.
All this connected with the adaptor from your cable shop I assume. (got it 
from Protovision ppl) --- just hardwire - hacked to become XM instead of XE.

ANY guess ??? I'll try anything --- still regarding myself as someone knowing 
a little about drives... :)
