Is there any revival from this Seagate 58 Grenada ?

[Carmet L]

Hello

The surface on head 0 is scratched, other surface and other platter are not damage.

Is it possible to revive the drive somehow using some technique ? 

Thanks you.

[t...@desertdatarecovery.com]

Thoroughly clean all platters.

Cut off H0 on a donor set of heads.

Alter the head map in ROM to remove H0.

Pray..

As this is a Grenada you will need to pray hard…

Can you make one of these drives operate from SA on head1 surface ? 

I have started to praying hard for this as customer is emotional.

What would you want to change in ROM parameters to accept no head 0 ?

Thanks you.

Its all described in the very underused Seagate F3 manual…

Thanks you Tim.

I am a hoping to solve this case now

[Carmet L]

If the donor has the same preamp as patient but different first 3 on serial number, will the donor heads still usable in patient, or does the first 3 on serial number have to match as well ?

[pbzcbf...@gmail.com]

I believe the first character of the S/N is the manufacturing location. The second  character appears to reflect the number of heads/platters.

[Tim - Desert Data Recovery]

Indeed. First three characters are pretty much essential.

[Carmet L]

Thanks you.

What if the other way around, the first 3 serial donor match patient but preamp is different number ?

I have several donor that may match but I don't want to chop them up if they would never work in the first time.

[Data Recovery Guru]

Preamp must match.

Ok thanks you everybody.

First 3 on serial (1st number can get ignored) and then preamp first prefix (e.g. B6) must match for the donor to works inside patient drive.

[t...@desertdatarecovery.com]

Personally I think that depends on the drive model. Some are far more forgiving to different preamps.
