I have a Maxtor Maxline Plus II 250GB ATA/133HDD with information:

Code: YAR41BW0 (Firmware)
SN: Y628J0WE
7Y250P0 060907

The drive stopped working one day and is now recognized by the bios as
"Calypso". I also set it as secondary slave with a 40pin cable, and tried with multiple ide controllers (Promise, SiS and Via). Then the Bios hangs most of the times, and all diagnostic tools do not recognize it's size, they think it's 0 gb.

I have an identical drive and i swapped boards. No difference at all, same things happened.

I searched the net and found out that it's a "G-list" firmware corruption problem.

So these are my questions:

The firmware is supposed to be on the board (an eprom or something), right? So when i changed boards it should work! Why it did the same thing since i put a board with a working firmware on it?

I found many firmwares "YAR41BW0", but from other models. I guess they won't work with my drive, right?

Can't i use somehow the second drive to restore my data from the first drive?

Thank you all..

Hi,

The most of the FW is on the disk, that's why PCB swapping won't solve this problem.
The problem is caused by one or more damaged FW module, so there is no trivial solution for this matter.
If U really need the data, U'd better find somebody with the experience and the tools to recover your data, otherwise U may make it impossible to recover at all.

regards,
