I check that. EPROM doesn't have any of these number. Or may be i made a
mistake: the eprom is the big chip with a  metal sticker glued on it ? Dos i
have to remove this sticker to see the label ?

Okay, in fact, the first partition (after driver and partition table) is a
HFS partition. I can move partition with the mac tools, so i'll do that. But
i can't format the GS partition with PRODOS, as my SE/30 dont let me doing
that. The formatter toos have no Prodos Format option.

the drive is an 2.4 Gb Fireball.

Done, by manually copiing SCSIManager and SCSIHD.driver, as the installer
method destroy each time my boot disk (6.0.1). When i dos that, my //GS hang
soon after booting.

There is an internal switchable Termination, set to terminanted.

? I dont know if the drive have this feature.

External drive is set to 2. The wheel is broken, as i canot change this
number ;-).
I will check the jumper. Actually, it is on the rightmost position of the
card (0, I thought).


Thanks for these informations.
