Hard drive repair reassembly

Recommended Posts

Hello,

Do you need a class 100 cleanroom to open up a hard drive and replace head and platters? Has anybody successfully reassembled and repaired any HDD without a clean room?

Any suggestion will be highly appreciated :)

If you're just swapping the PCB you don't need a clean room...

OTOH if you're swapping heads or whatnot, well, then you do. But getting that swapped is a huge crapshoot in itself. It's possible... but I have yet to hear of a successful amateur long-term swap, cleanroom or no...

This might be possible for a knowledgeable amateur such as an HDD company employee to do as a novelty project, but getting reliable operation out of the drive after a head/media swap is almost impossible outside a factory setting, even with a clean room.

After you swap the heads or platters, the drive will need to re-run the factory optimization and flaw-scanning procedures. If you are not an employee of the HDD manufacturer it will be difficult to gain access to the equipment, software, scripts, and parameters necessary to do these operations on your particular drive model.

Without optimizing the drive for the new heads and media, the drive will be extremely unreliable and may not even come ready when you power it on. This is of course assuming you had an exactly identical drive to take parts from.

BTW, in the off chance you gained access to some gray market drives (factory rejects) and are trying to repair and sell them: don't bother. The factories already recycle parts as much as they can, e.g. if a drive fails the factory process due to bad heads, they will replace the heads and send the drive through the process again. The drives ending up in the garbage heap really are trash and they are supposed to be destroyed. Trying to refurbish and sell that stuff is unlikely to succeed and is also illegal in most countries. It's theft.

Even having access to said Class 100 cleanroom does not always result in a successful result. Too much goes into making a working drive to make it a simple swap procedure for repairs, save for *maybe* a burned out chip on a board or something like that.
