I join you: thank you very much for the pg driver Grant.

I am using the latest paride and pg drivers (present in 2.1.108) with
no problems when I write at 1x speed to a SureStore 7100e. When I
write at 2x I get SCSI errors.
We came to the conclussion that this computer (which is very old) does
not have EPP o ECP parallel port capabilities so the only way of
writing to the 7100e is by using 1x speed and using the parallel port
in bidirectional mode.
H-P's web site says that in order to write at 2x ECP mode is needed,
and I confirmed this.

I guess you lost that CD. Why don't you test the whole thing with
-dummy and -speed 2 and make sure it finishes without errors before
trying to burn?

Are you sure your parallel port supports ECP or EPP?
>From what I see above, your parallel port is set for compatible mode
(mode 0, 4 bit). With this you won't even be able to write at 1x
speed. Go to your BIOS setup and change the mode to at least
Finally, in order to write at 1x speed and in bidirectional mode (mode
2, 8-bit) Grant recommended me to load the pg driver with delay=0.
Without this I could not even write at 1x speed but as soon as I
loaded pg with delay=0 everything started to work flawlessly.
