Thanks Mr.Vulcan
I'm sure that the HDD enclosure has set a password on the hard disk, this is wrotten in the manual of enclosure...

the first time I plug the Key into HDD enclosure the password created in HDD....and when i plug the hdd in another box it doesn't work...
I tried with a laptop, the bios detecte the HDD..but when i want to start installing windows it ask for password [ hard disk protected enter password]
but when i came back to first HDD enclosure with smal key it work...
So the smal HDD enclosure created a password on HDD in order to don't use it in another PC or HDD enclosure
Really I don't care about DATA on hdd...i want just to solve my HDD ( in fact i have 2: 320 GO & 60 GO) both of theme i have insert in this fucking HDD enclosure.
i need i simple sofware can erase password on hdd, and how can i use ( on windows or dos)
Thanks Mr.Vulcan for you help...and for all memebers
