Working with big quantities of information? You know the panic moment when you realize that you need some information that you deleted a long time ago. This is the subject of this post : How to do a deleted file recovery. 1st lets start with some general data recovery tricks, valid for all type of data devices, PC’s, Mac’s, phones.
Don’t forget to back up your files. As life coaches like to say, there’s something positive about every negative thing that happens to us. When your USB flash drive suddenly disconnects from your computer or your operating system starts to insist on checking your SD card, it may be a blessing in disguise. These early warning signs give you a chance to properly back up your files, if you haven’t done so already. We can probably all agree they are much better alternative to a sudden, irreparable failure.
The first step is to remove the hard drive from the device if possible, or otherwise stop using it. Any actions, even installing a recovery app, risks overwriting the files you need. The good news is that when you delete a file on a drive, all that data doesn’t immediately go away. The computer mostly erases the information that points the computer to that chunk of data, which will remain until it gets written over. This works differently depending on whether you have a magnetic spinning disk drive or a solid-state drive (SSD), which you’ll find on most modern computers. But either way, recovery is possible.
However, you should know that this technique wouldn’t work with most modern drives that have a unique microcode attached to them. For such drives, you’ll need to locate the TVS diodes (fuse) on the drive and test them with a multimeter to see if either of them has shortened. These diodes fuse if you attach the wrong power adapter to the drive or experience a power surge. If any of the diodes reads 0 ohms on the multimeter, it has shortened. Just remove it and voila! If the problem is something else, replacing the PCB might be the only option. You’ll probably need to buy a new matching one from the manufacturer or an online seller.
If Your Drives Spins Ups and Is Detected by Your Computer, But Hangs When You Try to Access It: This usually means that the magnetic media is degraded. Basically, there are a large amount of bad sectors that the drive is trying to read, failing to do so, and hanging. This is a common problem that occurs over time and can be worked around, but only with professional data recovery equipment, more specifically a hard imager. If you look at the SMART values of the drive you’ll notice and large amount of reallocated sectors to confirm your suspicions. If the data is important then send it off to the pros.
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.
