Western Digital Head Swap – Donor Drives

by Sep 25, 2017

On modern Western Digital hard drives it is not usually difficult to find a compatible donor for a head swap case. Use the following information at your own expense/risk.

Typically you try to match the full model number (e.g. WD20EARX-22PASB0), the TJ, VJ, T2, V2 in the DCM code, and get a close date. The second part of the model, after the dash, can be reduced to matching the 2 or 3 middle characters depending on it being 6 or 7 characters after the dash. There is also some information about slider matching that can help, but that’s beyond the scope of this article. And don’t forget you’ll need to watch the number/location of heads as needed.

Unfortunately with competition for parts and so many scalpers out there we often find ourselves using broader drive matching criteria. In our lab we usually try to find a donor in the same WD drive family (e.g. Saddle G6) but sometimes we cross families, we pretty much disregard the date. Most recommend using the same 2 characters in the DCM code, but for Firebird, FBLite, and Helios we often use a T2 DCM for a donor when the patient has a TJ DCM and vice versa. It really comes down to experience. It’s better if you have a few donors on hand in case one doesn’t work. If you have a rush job and only order one donor with limited matching criteria you might just be disappointed. If you are just starting out or don’t have a lot of donors in stock then try to match as much info as possible to increase your chance of a compatible donor. Here is a short list of some of our successful head swaps to give you an idea of what can work. Your mileage may vary.
