Hi Guys

I have a Hitachi HTS723232L9SA60 with H3 damage and scratch the outter edge of the platter (see attached).

Just wondering any chance of recovering the data, thinking of head exchange with new donor drive......but not sure if the damage area has SA.

Thanks.

Hello TerraNova,

I think SA is somewhere in the middle of this drive. Maybe someone else can confirm this for you.

Nothing to do SA Area there.
no bad head before that , bad height yes!

Looks like parking zone has caused problem. Heads might be ok?

I'm guessing this lost #3 head and got stuck between the platter and head ramp?

I think i can help.
I have some special trick for similar cases.

H3 virtually grinded off, no more h3 , what do you guys think, head exchange will work?

Ramp is ok, H3 gone, the rest of the heads are ok.

head exchange should work. might have to clean platters though!

Had a similar problem with a WD. Those heads just seem to pop off every once in a while for no reason. The head got jammed under the parking ramp and scored the platter. It was a good recovery though once all the debris was cleaned out and the heads replaced. The area where the scoring has occured holds no data, and as long as the new heads stay off of it, you should be fine. Let us know how it goes.

Thank you guys for helping out, managed to recover most crucial data.

I made a limitter to prevent head from moving to the damage area and some tweaking in DE.

good thread!

Can i ask how you made the limiter? I'll assume it was mechanical (a lump of something) which makes me wonder why the controller did not shut the drive down when it hit that resistance? Also, as this drive has a ramp and parks off-platter, I am wondering how you managed to load the heads onto the platter on spinup without damaging them?

Thanks!

who sad it is mechanical, and who sad "it hits" any "resistance"?
There is a lot of way.
Use your fantasy! (if you have)

hmm, ok Janos, you have got my imagination working (i have never had a real case like this, so it's all I have

I can imagine with DE, he can turn off the head on the troubled platter over a certain range of sectors (the bad ones), I also imagine there is no or very little data on that extreeme outside of that platter??

but what I can't imagine is how he spins up the disk without the parked head damaging itself as it crosses onto the cleaner areas of the platter... i would imagine the wear to be higher (rougher) than the air cushion would clear?

Thanks!

If you look at the picture you can clearly see that the damage was to the unused area under the plastic head ramp. This hd lost a head and got stuck at the ramp in my opinion. The heads are so small its easily lost or overlooked.

... or the magne can capture it, or can stuck somewhere else....
I have found it sometimes some really extreme places....
