Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

Hi Guys. I need some advice. Having trouble sourcing an exact match for this drive....
6y250m00656ab
YAR51FW0 KMGD
I have managed to find a few close matches.
6y250m00656ab
YAR51FW0 KGCD or NMCD
and some not so close....
6Y250P0062211
YAR41BW0 KMGD.
so my questions, which donor drive if any should I use for a head stack replacement?
I normally try to match firmware, 4 letter code and model, do these drives need such strict requirments for donor drive compatibility?
Thanks
HDD Spaz.

This one
6Y250P0062211
YAR41BW0 KMGD.
The 4 letter code matches for head and preamp match, and the 06 in the model determines head type also

Cheers HDDGuy,
I hope your right. That contradicts what is says on the HDD Guru Head Replacement FAQ document but I'll give it a go.
Anyone else got any thoughts?

KMGD and 06 would be sufficient, material mix do match. P.s. Yar41bw0= likely REFURB DRIVE, so beware

. Expect slow imaging because of differences in heads! Post the result.

Totally agree

Have to totally disagree YAR41BWO is a regular firmware for DM9 drives

Here we have tons of drives with that fw clearly written 'REFURBISHED TO MAXTOR SPECIFICATIONS' and/or one label over another. Also heard this from other tech.

I have loads and loads of DM9 with firmware yar41bw0... I think more likely is just that these drives failed so often that there are more refurbished ones out in distribution than other models.

I have refurbished thousands of DM9 drives, but Code: YAR41BWO is just a firmware nothing more.

Yes, i have seen a lot of Refurb. drives with different types of FW. This does not mean that all drives are refurbished.
You must of got a big load of previuosly ref. drives in Italy
Maybe its a coincedence, but I used to buy a lot of returned drives from a company in Italy and a lot of them were previously refurbished, but that was a long time ago.

I meant brand new, off the shelf and bag sealed. Perhaps is a coincidence... P.s. All the drives with 'refurbished' label I had for dr, suffered from bad head crash and ground surface.
