8) only different of 1 number what to suggest better if you used your experience. if it is spin down you can recover data without head swap...or clicking go for the head swap.

Yes, heads should be compatible.

DataPlanet . . . what are you trying to say?

I don't think the "Location" details is correct actually

Chances are 50/50. They may differ slightly, but that's the subject for an experiment.

I'd give higher odds than 50/50. Passport heads are amazingly cross-compatible, in my experience.

Yes, what I meant is more about the reading speed, not complete incompatibility. What we saw here is with one donor head stack drive reads poorly, with another -- everything is OK. Adaptives affect compatibility, heads are almost identical, but if manufacture dates differ significantly, then there's chance that searching for another donor will be necessary.

As for the 50/50, I speak "Russian-style" a bit. That's why I have mentioned an experiment, which will show that heads are either good or not so -- that's 50/50 :)

I guess the "Russian-style" must be predicated on understatement? How would I know from what you wrote, that it had anything to do with reading speed?

:D

I believe that's the question my English isn't enough to answer properly :)

Generally it's "practical laziness" -- for 1 TB hard drive it's usually more effective to get another, more fitting donor than waiting while a slow head stack is reading.

I think you're well aware of this situation, when you spend most of the day "talking" to RAID array images, hard drives and a bunch of geeks cracked the same way, having social life on fortunate weekends only, speech-related part of the brain gets bad sectors in it rather quickly :)

As for the wording, we have a corny joke saying that "During the combat commander automatically switches to foul language, tripling the information density". With the amount of work and time I have for forums, sounds very applicable to me :)

Hello,
Here is the way to test that the heads are compatible or not,
replace PCB of each drive and check if the hdd clicking then head not match, if not clicking then head matched.

This hdd is Helios series. try to connect 1692-005 PCB and Diagnose it by shorting TV9 or TV10 points, then repair slow problem.
Some time Helios hdd show head weak but in real no head weak.
if your hdd is clicking then its head damaged, if running smooth then heads are OK.

I have not experienced much "slow heads" on Helios. Rather don't work.

difference between 4 and 5 is in PCB
There is not enough data to tell difference in heads

Don't most WD drives click and spin down with bad heads? How can you say that if it spins down, no head swap is needed?

Could not the Heads be compatible (match), but click because of adaptives ?

My experience agrees with Jon's, Passport heads are very cross compatible. I wouldn't be surprised if you stuck a piece of burnt toast in there as a donor it would work.

If adaptive mismatch in Wd hdd then head not clicks. if the order of head is changed in both hdd then it gives clicking,
donor head map order = 0 1 2 3 4 5 6
patient head map order = 2 3 4 5 6 7 8
then by this order the hdd start click, if head map order same then hdd gives you smooth sound of head move, but hdd not detect because the ROM is not match with hdd SA. it will tell you that the head was interchangeable or not.

I use two different hdd in head replacement
donor hdd firmware code = 00S9B0
patient hdd firmware code = 63M8B0
Both hdd has same PCB number 1640-001

I connect the patient PCB to donor hdd and it gives me smooth sound, then i replace heads and data back.

Same thing i apply on other model hdd, if i not get the same model.
well it is called the six sense.

try it , it is a good trick

Clicking is caused by the actuator are hitting the limiters. As per the post below, adaptives mis-match (failure to read Servo) does not cause the actuator arm go as far as the limiters, in search of servo info, and cause Clicking. But, head map mis-match cause the actuator arm to go that far, hit the limiters and cause clicking. How can this be explained technically ?

Hello,
I think i tell the way to test the head either they are compatible or not. i not tell the solution to find damaged head due to preamplifier, broken head, servo failure, or other.
