IDEAL DONOR HEADS HITACHI

[sempre]

Hi to all!!

HEADS bads model HTS541616J9SA00

in the site of hddguru one sends regards:
Hitachi 2.5' PCB revision match is mandatory + contry made

With its experience and that it recommends?

Tovarish,

In my experience, if you match the country and MLC code on this series you will be OK.

Some are DA1905 and others may be DA1712.

How important really is the MLC and country to match? I have replaced defective heads with parts that matched model alone and has been successful.

Maybe I am just lucky??

Hi hddguy!

its experience was with the same model of this post? (HTS541616J9SA00)

[hddguy]

Yes.

Part was purchased for a specific client, client decided he did not want to proceed, so parts were used on a different clients disk, same model different MLC and country, all data recovered


Maybe anyone else has similar experiences?

Yes.

Thanks for reply!

somebody has more similar experiences?

Yes, have had success without matching MLC code.

I don't think country code is very important with this series.

But I have found, for example, that some 120 GB drives have 4 heads and others have 3. The MLC codes are different, but the model numbers are the same. You could have a situation where a 4 head Hitachi couldn't be read by a 3 head donor. That's why I suggest matching MLC codes to be on the safe side . . .

I had one recently where two drives with same MLC and same number of heads were different size... 80GB and 100GB respectively. I thought maybe the size was artificially limited so tried swapping them anyway, did not work.

Just had this problem, same model and different MLC with 3 heads, donor 4 heads. I noticed Apple branded drives have 3 heads. Weird...

[jono-ats]

Apple drives can have EITHER 3 or 4 heads . . .

HTS541616 ALL I see is have 4 head... easy to swap.
HTS541612 got 3 mdel of head. 012,123, n 1234.. not so difficult to swap head too.

I have test many time.
since it is still HTS... come from Apple and Standard PC... it is just the same manufacturer..
So what is the different....

I have seen many occasions that a disk with same model, part no and mlc have different amount of heads. I needed to change heads on a 60GB travelstar, which had 4 heads, 3 donor drives purchased all with 3 heads. In the end I had to purchase a 80 GB donor drive because I knew it had the 4 heads. It worked though.

So I guess I was partially right! MLC is not for compatibiltiy, but for Head Map.

Thanks prodata

Hi to all!!

Exists some possibility of a model HTS541612 of 120gb with 4 Heads to be a donor for one hitachi (HT541616) of 160gb? Somebody already tried here?

[hddguy]

I think if family is same (HTS54) and heads number is same, then should be OK.

[HDD Spaz]

only one way to find out. report your findings.
