reading a ydl partition from X

[Will Wade]

Hi there,
Apologies if this has already been posted before but I cant find it in 
the archives..  Im sure it must have come up before though..

I had ydl 3 running on my imac and now due to it croaking Im trying to 
read the drive over firewire. The mac OS9 partition loads up and I 
"think" I can see the partition I want but cant get the mount -t to 
work..

heres the pdisk output:
/dev/rdisk1  map block size=512
    #:                 type name                  length   base      ( 
size )
    1:  Apple_partition_map Apple                     63 @ 1
    2:     Apple_Driver_ATA*Macintosh                 54 @ 64
    3:     Apple_Driver_ATA*Macintosh                 74 @ 118
    4:   Apple_Driver_IOKit Macintosh                512 @ 192

   10:      Apple_UNIX_SVR2 untitled           230534269 @ 10720451  
(109.9G)

number 8 is what Im intrested in so I thought I should type:
  mount -t hfs /dev/disk1s8 /Volumes/OldIMac
the drive light goes orange (reading) but I get:
/sbin/mount_hfs: Invalid argument
Is that not a hfs drive? If not then what do I need to mount it?

thanks

will
