Toshiba - MK5075GUX USB Native PCB [ Always Busy ]

[Amarbir[CDR-Labs]]

Hello Everyone ,
How Are You All Been Very Busy With My New UDMA "Yup Got It At Last " Last Month .So Now The Lab Has Virtually All Good Tools For HDD Work .SSD And DE Are Also Activated In This .Today i Got a Toshiba 500GB [ Native USB PCB ] Model No MK5075GUX .I Wanted To Attach This With The Tools I Have and Swapped The ROM From This Native USB Board To a SATa Board .These Are The Details .

Patient :

MCU : 88i9117-TLA2
Motor Controller : TLS2505 [ I Matched The Second Line To Donor Board ]
ROM Chip :IC602 [ Swapped To Donot Board ]

Donor PCB SATA Board :

MCU :88i9117-TLA2
Motor Controller : TLS2505 [ I Matched The Second Line To Patient Board ]
Rom Chip : IC602 [ Borrowed From Patient ]

If The First Line in This Motor Controller Is Not Required i Am Sure I Have Done it All right .The Patient Board Was FKN8NB And Donor SATA Board Was FKN82B .The Drive is Always Busy [ Spinning Does Not Stop , I Could Not Judge If There Was Any Clicking Even With a Stethoscope ] . Can Someone With Experience Suggest Me Something Please

Hello Everyone ,
Does Anyone Have a Clue.I Put The ROM Back Into Native PCB [ With USB Interface Today ] And Once Connected The " Device Manager " Under Universal Bus Controller " Show USB Mass Storage " . No Other Stuff is Detected .I Am Unable To Get The HDD Out Of Busy Mode [ Even When Connected To SATA PCB With Native ROM ] .Has Anyone On HDDGuru ever Got This Case " Toshiba MK5075GUX " . The Last Thing I Will Try is Tapping SATA Via Native Board And Native ROM .If This Does Not Work Then i Have Only Two Options

1 : ROM is Currupt
2 : Something Wrong With Heads .

What Else Could It Be ? .
