head swap on HDP725050GLA360 P/N 0A37728

[hddr49]

Hi there,

I'm looking for donnor drive.

This P/N is very diffucult to obtain, so I try to obtain information on users that have successfully swap heads with differents P/N

(original topic here for this drive : viewtopic.php?f=2&t=7842)

Thanks for help !

I think it's better for you to get a donor than to do hotswap on those.

[hddr49]

yes, but I don't find any donnor for this one.

search for it since 6 month...

Why don't you forget about P/N and just buy the same model?

Why don't you forget about P/N and just buy the same model?

Totally agree. PN may be preferable, but in my experience it does not always need to be perfectly matched, in some successful cases there is even no match to PN...

[hddr49]

unfortunally already bought 2 of same model

heads don't match. Unlucky guy ?

donnor heads are ok, I back them into donnor drive
patient heads don't work in donnor drive


I search same P/N or same MLC ... what else ?

[dmarques]

What do you mean they don't work, they knock?

[hddr49]

yes, they knock.

[dmarques]

Do you have microscope to check head pattern?

[hddr49]

no, I don't.

But I can buy one if relevant.

[dmarques]

I think it's a must have tool in your LAB!

[hddr49]

ok then.

where should I look on the heads to see head pattern ?

compare with other good heads ?

[dmarques]

Hi,

You should compare it with your donors.

[hddr49]

thanks for your helps.

I will do this.
