Best ways to Western Digital hard drive data recovery

Working with big quantities of information? You know the desperate moment when you realize that you need some files that you deleted a long time ago. This is the subject of this post : Deleted file recovery. 1st lets start with some general data recovery tips, valid for all type of data devices, PC’s, Mac’s, phones.

Have a data recovery program ready for use. When your hard drive goes bad and you lose valuable files and documents, it’s time to turn on your favorite data recovery software solution and recover everything back from the bad hard drive. We highly recommended Disk Drill for Windows and Mac OS X. The main advantages of Disk Drill are its ease of use, support for more than 200 file formats and all common storage devices, including iOS and Android smartphone and tablets.

It’s a bit simpler on a Mac, using an intimidating-sounding tool called target disk mode. You connect a nonworking Mac to a working Mac and treat that nonworking Mac like a big USB drive. This can be useful if, for example, you need to get files off a computer with a screen or keyboard that doesn’t work. Connect the two computers with a USB-C, Thunderbolt 2, or Firewire cable. On the broken Mac, turn it on, and press and hold the T key while it starts up. Or, if the Mac is already turned on, go to Apple (on the upper left of the screen) -> System Preferences -> Startup Disk -> Target Disk Mode.

So, if your hard drive fails, you’ll need to take care to stop working on it immediately. Even if you’re not directly accessing the data on it, your computer is probably writing something to it thereby risking your shot at data recovery. Once the data is overwritten, there’s no any chance of getting it back. So shutdown the computer that is connected to the hard drive and unplug it.

There are two main causes of failure here, either a TVS diode (fuse) has shorted due to overvoltage, or a vital component on the PCB has failed. Hard drive PCBs often have two TVS diodes which act as fuses to protect your drive in the event of a power spike. There will most likely be two of these: one for the 5v and one for the 12v rail. If you accidentally plugged in the wrong power adapter to your external drive, or you experienced a power surge, a TVS diode might have sacrificed itself. If the shorted TVS diode is the only casualty and the rest of the PCB components are OK, then simply removing the shorted diode is enough to bring the drive back to life.

Older laptops that were constructed with traditional hard drives were fairly simple to pop open and fix. You could unscrew a few screws holding the case together, and then plug into the drive via a universal SATA port to retrieve the data. Opening the actual drive itself is not without risk, or advisable, as dust could and will enter the drive, causing contamination and potentially additional damage during the process. For example, older drives would be subject to something called stiction, and sometimes became ‘stuck’, whereby the head and actuator were locked or stuck and the motor failed to spin, causing the hard drive platters to spin improperly. One trick that had some reported success involved placing a hard drive in the freezer, which would cause the metal to contract and become unstuck, at least long enough to offload the data.

If you have a storage device that you have not used for a while and you realize that you deleted information a long time ago, it is possible to recover it. There are different tools when recovering files, and one of them are data recovery software, programs specialized in the recovery of any type of file and that work under any operating system.
