firewire drive not showing up.. (it used to work fine?)

[supernova777]

im trying to back up my sample library 500gb firewire drive..
and its not shwoing up on my qs 933
obv running 9.2.2

any ideas for me to check?
the version of the firewire extensions says "mac os cpu software 4.7'
theres 3 extensions

firewire authoring support
firewire support
firewire enabler

when i run drive setup it shows the drive.. but it says "not supported"

plugged the drive into my imac 2008..
the partition was not mounted automatically there either
i had to go into disk utility and force it to mount

is this because i had unmounted it previously + its remembering the setting? or something?

wierd

1) Did you used HDST (Hard Disk speed Tools) to Originally Partition it ?
2) Did you use OS X or OS 9 ?
3) HD Actual size (500GB) and partition sizes ?

its a WD passport fw800 drive with a fw400 adapter
single partition 500gb

i got it to mount on the imac..
it used to work fine on os9 (and 8.6 with the os9 fw extensions overwritten the 8.6 ones)

that why i was wondering if there a preference for it to mount or not.. when i plugged into the imac it showed up in disk utility but didnt mount automatically

There might be something wrong with your fw800 to 400 adapter. Does it use an external power supply or is it bus powered? I am reffering to the hdd.
