Cleanroom Recovery - Head Stuck Between Platter/Ramp And One Head Broken

Postby Amarbir[CDR-Labs] » 11.02.16, 14:38

Hello Everyone ,
I have this helios 1tb hdd .Model no is WD10TMvv-11TK7S2 .Upon Inspection of the HDD in My Clean Room i noticed that the head did not mount on the ramp and was lying very close to it on the platters .The Ramp Was Removed And i Carefully removed the head .Upon Inspection i could see some damage on the outer side of the platter and 2 to 3 odd spots a dent/pit .also on the surface i could see a small 1 inch scratch in the middle .The Top Head was broken "Just the gimble " and stuck to top lid .The portion of the slider that mounts the head had rest of the heads intact but i did notice 2 to 3 of them very slightly bend there ".This bend is not on the main slider metal arm but the metal arm under the end of the slider that has the head .This is what i plan to do to solve this can someone with this experience share with me on forum of via pm if the is right approach

1 : PCB Swapped To SATA [ New PCB No Not In Acelab list hence posted the same ] - > viewtopic.php?f=155&t=8376&start=15#p30379
2 : I Run The HDD And see If It will Work With Those Heads " Would the broken gimble head of top layer get suspended in air due to air velocity of will it hit the surface " this is my first question .My second question is that if it will hit surface then no point bothering to run this headstack without a swap but if according to your experience it will not hit surface might be it gets a issue in mounting back to ramp as it is slightly lower to surface due to gimble not being present and if you say it will not hit surface and also mount back properly then i can give it a try and might be i can bend the head so that it never comes near surface and also the top slider arm end point goes fly past the plastic ramp .Another Question is that as the gimble is broken would the pcb and the Preamp chip have a issue with this and start clicking as there is no physical contact " due to it being broken .The last question is that whats the tool approach in this "Disable last head in rom " or leave rom as is and disable in ram and then clone good heads .

PS : Feeling on cloud nine today and striving for hard work .

In my opinion it isn't worth the risk of causing permanent damage to the platter. Even if it does "fly" you don't know that it won't start to vibrate from operating way outside of it's design parameters. I'd guess that it'd flap away banging bad sectors all over the platter. Why not just cut it off completely if you're intent on running it without the head.

Jared ,
I just pressed the "Topic is solved button lolz " . Anyways i would say a new head stack is way better cos if i do not do that i still cannot clone head 4.And if i do run the same headstack clipping the head or bending upwards would be better But My question still is not answered by ace ? . If the black read/write head or slider whatever you call it i am still not clear BTW is broken but system heads are intact will drive click and spindown and then do we have to use ram headmap editing or something else

Judging by the fact that most drives I've seen with missing sliders also have severe media damage, I'd say it's a safe guess that it will not "fly".
