hi all i am having an issue with a dropped seagate drive model no ST3320820AS, drive was dropped during operation and motor froze completely.
I successfully loosend the motor and got the drive spinning, however the motor was spinning very loudl and had some vibration to it so drive would not become ready,
i moved the platters, heads and magents and pcb to a new donor chasis, drive will now spin up correctly and sounds normal, however drive will not id.

the drive spins up and starts clicking, when running through pc3000 it takes about 1 to 2 minutes and gives the followig terminal output,

However at the end of this i get the DRD and DSC lights but the drive sounds like it has spun down. I launch DE and the drive gets Id'd correctly, with correct model, serial and firware all displayed.

i start the copy process, the drive starts to spin up, click, attempt to copy and then powers down with the following messages

->LBA = [ 0.. ], Step = 256
Error - Set UDMA = UDMA66
->LBA = 0, Step = 256 [Drive is not ready!!!]
Software reset...
Hardware reset Ok
->LBA = 0, Step = 1 [Drive is not ready!!!]
->LBA = 0, Jump = 200
Software reset...
Hardware reset
Power OFF
Power ON
Software reset...
Wait 25000 ms. Drive is not ready! Power OFF!

i tried a different set of heads and the same thing still happens, platters seem to be spinning correctly and even with no distortion visible.

could this be an alignment issue, during the transplant process i used HPE too keep platters correclty aligned and removed as a set.

Any ideas on this are greatly appreciated,
thank you in advance

Appears problem with platter. Default setting will not work. Try backward clone, set power on/off on drive readiness (set the time to max 12000 ms). Set read mode to UDMA33 or hardware reset.

Had some success with rather similar cases before.

Good luck

Agree.

thank you for the answers guys
i will try this later on tonight or tomorrow and post

thx for answers

One more note: It will be a nightmare to capture the full 500 GB disk image as the process is likely to be deadly slow even if this works.
Clone only critical area you need.
Brief hint: capture sufficient info (normally in the beginning part of disk) for you to open critical directory -> Study the bitmap location while scanning directory or open/copy file -> zoom on the critical zone to clone the missing part needed. You need to do this back and forth. It is painful but it saves me time and effort in the end.
In general, for problem drive, it is easier to "clone" a range than to copy the file directly. You need to judge to see which one work best.
