Its burned i tried another one the disk spins perfectly but not detected

For the following Maxtor hard drive models: Fireball 3, DiamondMax 16, DiamondMax Plus 8, DiamondMax Plus 9, Diamond Max 10 and all MaxLine products there is also a GTLA Number on the model (next to barcode on the bottom of the drive). Format 1Y222J2223322. 1, 2 and 3 stand for numbers, Y and J for letters.
The numbers 1 and 3 as well as the letter Y need to be identical to be able to replace the PCB on these drives.

This number can be found on the large sticker on the top of the drive.

Unfortunately we can not give you any more information than this. Any of your DiamondMax Plus 9 drives could possibly have a matching PCB, however it is most likely to be an older one as the drive in question is almost 3 years old.

Kind regards,
