I've just tried to invol our new 400t's SCSI-Disk w6:0 and after choosing
option 1 (formating virgin physical volume) pressed <RETURN> twice, be it
by accident or through a tossing (word?) keyboard.

Be warned ! While this may happen quite easy it's a proper way to make Your
disk unrecognisable to invol, salvol, mtvol and so on : 'invalid physical
volume label','unable to read badspot list' ... 

Since I fear that our friendly HP-technician will take a time to find out
about a remedy, I wonder if somebody else knows how to 'destuck'. I 
assume that rwvol may offer a chance, but I'm not that daring to invoke it
without some hints.

Now that I'm at it : Are You also experiencing lots of nasties in the 
MD of the 400t ? 'EX'ing a commandfile, e.g. salvol, leaving it and
trying to 'EX' another just barks with strange error-messages in Hex.
Is that why the reset-button is on the front ;-) ?
