Howdy...

My first post here, and, please forgive me for any newbie terminology failures.

I have a Maxtor DiamondMax Plus 8 40GB hard drive that has a blown motor IC.

My question is two-fold...

Will replacing the PCB allow me to get to the the data (with a specialized utility, if necessary)?
If this is possible, how many of the following numbers have to match, and which ones can be different ?

• Model # (6E040L0510214-ABA K,G,M,A)
• Code (NAR61590)
• Firmware(?) # (B6FEB)
• Main IC # (ARDENT C5-C1 040111500 ARDENT-C5C1-840UK)
• Motor IC # (Texas Instruments SH6782B) (damaged)

I'm trying to find one as exact as possible, but so far the closest I've come across has a different Texas Instruments motor IC # than what I have.

I know the drive spins up, because I bought a near match board, but it freezes at boot (though it sees the drive is hooked up).

Even though I have a half-decent soldering station with multiple tips (MetCal), I don't think I'd have a good chance of success attempting to replace the motor IC myself (unless you guys have done it successfully, then I might try it, if no other option).

I'd be grateful for any suggestions, and I appreciate your time.

Thanks in advance...

B6FEB Should be fine.

If you can read the correct model number in your BIOS with the NEW PCB I think it's a match.


It could have bad sectors which could cause it to freeze on boot or SMART issue which would be firmware error (Drive should still work for recovery)

Thanks for your reply.

That's probably why the replacement board I acquired spun it up, but froze @ BIOS... it's a B4FEA (noob fail ).

I think I can find a B6FEB, but the motor IC (and likely the main IC as well), would be different. The code, model #, capacity, etc., however, would be the same as what I'm trying to replace.

Would this do the trick, do you think?

I REALLY appreciate your help.

It's not the board unless they gave you a defective one. Try another one identical if you can, then if the result is the same there is another problem - internal.

agree with ST
