drive mounting issue (SCSI on beige G3)

[Benjamin Warfield]

Ah.  I had for some reason picked up the notion that fdisk had been 
made capable of reading Apple partition tables.  Don't know why I 
thought that.  And I'd forgotten pdisk.  Why my previous web and list 
searches didn't correct either of these lapses, I could not tell 
you--sorry!  With pdisk, it rapidly became clear that I had  totally 
misremembered which partition was which, and so I tried again with the 
right numbers, and it worked beautifully.

Thanks!
