Not sure why you have a problem it should work for you.

And not sure what bootable media you are using.

Maybe verify the tool is not corrupt too and check if its up to date ?

tnx, i have seen this information before i use the tool.
the tool is update (version 1.05),
i dont know how to verify it’s corrupted or not. (the tool work with /? option, so may be it’s not corrupted) ( i download the tool from wdc.com in zip file and it extracted without problem)
i test it with several bootable media including : 1) a dos bootable floppy, 2) a dos bootable cd created with FDOEMCD.builder, 3 ) a dos bootable cd created with ubcd
with all of this bootable i got the same error then crash. ( with floppy i dont get any error, just crash)

how i can verify for corruption or what else i can do ? 

i used the alternative opensource (actually FreeSoftware) linux based tool -->   http://idle3-tools.sourceforge.net/

and every things went fine, i disabled that stupid head parking. :smileyvery-happy:
