IBM Hard Drive PCB swapping replacement guide

Swapping the printed circuit board (PCB) on IBM hard drives requires matching 4 things “EXACTLY” for your best chance of success without having to swap any chips from your old PCB to the new PCB. We recommend matching the full model number (IC25N030ATDA04-0) and the Part number (P/N) (07N7436) both of which can be found on the drive label. The third thing that is required for the PCB swap is the MLC (Machine Level Code) (H32162) which can also be found on the drive label. Last thing we recommend matching when swapping PCB’s on IBM drives is the PCB label number. This is a white label on the PCB that has 4 lines of letters and numbers. These numbers designate what chips are on the PCB. It is an absolute “MUST” that the first 2 lines match “EXACTLY” for any chance of success with a simple PCB swap (07N5445 F80181B).

If these 4 things are not matched “EXACTLY”, you will be able to get the drive to spin, but you will not be able to get the drive to be recognized to recover your data or use the drive. (See photos for examples).

If this is the case when you install the matching PCB you will need to transfer the 8 pin ROM chip from your original PCB to the matching PCB for the drive to be recognized in the bios to recover your data. These ROM chips are specific for each drive and a simple PCB swap with an exact match is not a guarantee without the ROM transfer.
