My MYBOOK included WD Diagnostics software, which enables me

You might wanna tell babblebot I and babblebot II about it.
They repeatedly say that it can't be done.


Unfortunately, I can't take a screenshot of the output, but I assure
"them" that it works - unless the utility is pulling numbers out of the
air.

The utility is called "Western Digital Data Lifeguard for Windows -
DLGDIAG for Windows". I suspect (not sure) that anybody can down-
load it from the WD site.



Bill was right! Even if I couldn believe it! :-)

I tried several times to read the SMART-status of my "my book pro"
(USB2.0 and Firewire400) with a Firewire-Connection and it didnt work.


After that I searched a lot at google-groups and found a lot of postings
reporting that the IDE-Commands cant be sent through Firewire


That's not my impression from this group. That would apply to USB.

or some Controllers.


Likely the latter. I believe the Firewire interface has a better defined
software interface for the Firewire "Tailgate" ( 1394 to IDE bridge).
http://www.t13.org/project/d1248r4-1394-Tailgate.pdf

" 1 Scope
This standard specifies the protocol for passing ATA and ATAPI
commands over the 1394 bus. It provides a common attachment
interface for systems manufacturers, system integrators, soft-
ware suppliers, and suppliers of intelligent storage devices. "

I'm not aware of any similar specification for an USB bus tailgate.


Now I connected my "mybook" with USB1.1 (dont have USB 2.0) and it
works:

With a firewire-Connection to my mybook the Mybook didnt appear at
"physical devices" and I couldnt scan it.

But if I connect the mybook after booting it appears, even if the
SMART-Mode cant be read at once.

But I can start a Smart-Scan with a pleasing result :-)

Unfortunately it says "SMART Status: Not Available"
