Western Digital WD1001FALS Data Recovery
This WD1001FALS model Western Digital drive is notorious for having issues with its firmware. Usually, it only has bad heads when dropped. It can be rather picky when you are swapping heads and requires a very close match for the donor drive. If you need the data recovered from your drive, please consider my affordable data recovery service!

Internal Notes For Western Digital WD1001FALS
Each model drive has a different set of things to think about when you are going to start a data recovery process. Below I highlight some of those items to think about. Included below are pictures of this exact model opened up so you can know what to expect when opening the drive.
In order to open this drive and work on it internally you will need the following tools:
- Torx TR#9
- Pry tool
This particular 1TB model has 2 platters inside. Each platter holds half of the data, or about 500GB each. You can see in the internal pictures that there is room for more platters, but there are just 2 platters installed.
Head Stack Information
With a total of 2 platters inside this drive, there is a head stack with 4 heads. One head per side of the platter. Note that Western Digital used a head stack that could actually hold more heads, but left the top empty as there are no platters to read data from.
Recommended Head Comb
I highly recommend HDD Head Tools for their Head Comb on this model. The SKU number for the correct comb set is HDDHeadTools4.
Things to watch out for
Be sure to reassemble the drive before testing anything as the head screws need to be installed for the drive to work properly.

Data Recovery Procedures
The Western Digital WD1001FALS is a fairly straightforward drive to recover. They don’t seem to have catastrophic failures very often, are usually a successful data recovery, and donor parts are readily available. We see drives with bad sectors and bad PCBs (specifically bad TVS diodes). Motors wear out on these at a decent rate which causes them to seize. This is unfortunate because a platter swap is almost always needed. They usually have multiple platters, so you need to disassemble the entire drive, platter by platter, being super careful to not mess up the alignment, or the data will be unrecoverable.
First of all this drive does not seem to have a very high failure rate. All drives fail eventually, but his drive is known as a pretty robust model. You can read more about how long drives usually last on my page dedicated to that subject.
Bad sectors, failed PCBs, Firmware issues like the Module 32 Slow Fix issue, and worn-out motors are common with this drive model as it ages.
Success Rate For Data Recovery
One of the only issues that can be present on this drive that makes recovery not possible is a damaged platter. Other than damaged platters, almost all issues with this drive can be addressed.
The PC-3000 by Ace Labs is the standard in the Data Recovery industry. Below are some basic procedures you may want to use when dealing with the Western Digital WD1001FALS.
Head Map Editing
This vintage of Western Digital is one of the few models where head map editing works normally. Usually, click+spin down equals heads and nothing is recoverable without head swap, but partials are possible here.
FW issue with these is the Module 32 error. This firmware issue is commonly referred to as the “slow fix”. This firmware issue can almost always be cleared using the PC-3000.
