Hello friends

I want u help on this case, Seagate 500GB wich was dropped ST3500630A

The drop caused, FDB seizing and movement of heads to the begin of platters, but doesnt looks scratch over platters
Was not possible to repair it the spindle, so need to did a platter exchange, after that the hdd spins, and i can hear the reach of servo mark, but then cannot reach DRDY , stay on BSY DSC.

This is the log by terminal after did platter exchange .

Donnor was same Model, Site code, and FW, i tried head swap even, thinking on a damage of heads caused by the heads i did head swap but nothing change same log and same problem.

Like u can see the hdd reach Servo mark, and its possible to load SA, the second time , doesnt show , SFI;AMR after did type "R" inmediatly show

T> but stay at Not Ready

Any idea, im think looks like a missalignment, but how to solve it, if u want post here or on PM

Give it more time to init

Agree. Maybe platter relative skew. Should init in a reasonable time, expect a LOOOONG image time...

There is a possibility for disk disallignment, because of the drop or transfer of the platters, which is very hard to determine now.

you don't need to post sounds. I can "hear" that "scratchy noise" from the terminal log
Drive should come ready or it should return an error (like overlay failled) and go on T level
it is of course alignment
Error 15 is: Rd/wr seek timeout code
Error 16 is: Seek timeout


You can try to re-align platters but it is hard work

Doomer, just a question: how much 'skewing' is tolerated in microns/degrees? I mean relative skew or rotation between platters. Doesn't PES and TF work ?

Any other people with this fault? I had a disk in which gave the following log. It sounded horrible, and took a couples of attempts to become ready, but then imaged OK and quickly too. The owner was not aware of any physical shock to the disk.

Happens.... but the reason need to be investigated as many causes can be (symptom is identical).

And NEVER assume customers are telling you EVERYTHING....

Got a 160GB one. With same problem. Drive was spinning but stayed busy. After swapping both Heads and PCB this are the logs
