To be honest, there are some risks involved with DIY data recovery. Therefore, if you would like to attempt data recovery on your own, you had better firstly refer to this article. We will show you 7 common mistakes which you must avoid.
Generally, when a hard drive fails, users tend to firstly try to fix it and recover the data like damaged PST data by themselves, instead of resorting to professionals at once. Such data recovery refers to DIY data recovery.

Therefore, you’d better get some help from experts. Of course, here we will give you a hand as well. You should prevent doing the following mistakes.
1. Launch CHKDSK on Failed Hard Drive
When a hard drive fails, many computer users will tend to run CHKDSK to fix the issues on the drive. However, facts prove that not only will it be unable to recover drive, but also it’ll cause data overwrite, resulting in completely impossible data recovery.
2. Replace Drive in RAID 5 until Two Drives Fail
Generally, in RAID 5, when a single drive fails, the array system will still be able to function. But, at this point, virtually the array is in a degradation mode. It means that a second hard drive will tend to fail with time going on. Thereby, you should replace the drive as soon as one fails. Never delay until two fail. At that time, data recovery will become pretty difficult.
3. Fix Physical Damaged Hard Drive via Software
As we all know, hard drive failures can be normally divided into two types. One is logical failure. And the other one is physical damage. The former can be fixed by a third party tool most of time. However, you should never try to repair a physically damaged drive via software. It may lead to a risk of data overwrite.
4. Open Hard Drive in Non-cleanroom
To fix a physically corrupt hard drive, opening it will be an essential and key step. But you shouldn’t open a drive at will as it demands a cleanroom. Hard drive is sensitive. It can get further damaged if being opened in a non-cleanroom due to a bit dust or excessive moisture, etc.
5. Pry Open Hard Drive Violently
Users may discover that opening a hard drive is not as simple as what they think. Also, since they don’t find the screws hidden underneath, some users will tend to violently pry open the top cover of the hard drive via screwdriver. This action will cause drive platter being seriously scratched, leading to unrecoverable data.
6. Swap Circuit Board Arbitrarily
In earlier times, swapping the circuit board on a hard drive is able to fix a failed drive at times. However, nowadays, suck trick is not useful any longer. When you have replaced the circuit board but failed to recover the drive, even though now you send it to professional recovery service, recovery will still become far harder.
7. Move Platter from One Drive to Another
Due to data is actually stored in the platter of the hard drive. Thereby, some users may think that moving the platter from original drive to a new one can restore data from the platter. This idea is actually wrong. This process will result in data recovery being impossible thoroughly.
