Top Tip For DIY Data Recovery – Don’t Do It!
When money is tight often we are all tempted to do those little repairs that we would other wise get professional help to do and data recovery is no exception. Quite often data recovery are presented with hard drives that have been opened in an unsafe environment and also drive that have sustained further data loss through incorrect use of DIY recovery software.
In most cases this software will be a hard drive recovery programme for a hard disk drive that has suffered from some form of logical table corruption and will not assist with
- Mechanically failed devices
- Degraded hard Disk Drives
- Devices with electronic failures
This software will of course not be able to help and if the drive is degraded or suffering from a mechanical failure attempting to run this software will in most cases cause further damage to hard disk drives, potentially making the disk unrecoverable.
The software itself is very often very reasonable priced – usually under $100 but is only good for one purpose to recover either deleted or logically failed drives, so if you are not sure what you are doing trying to do a self recovery can in the long run cost a lot more.
In a recent case a teacher brought in a laptop hard disk drive which had been previously diagnosed by the schools own IT department. The teacher concerned had done exactly what any person probably would do and trusted that the onsite IT dept at the school would have a degree of knowledge and competence when dealing with a suspected HDD failure. Unfortunately the opposite seems to be the norm in many cases.
In a typical case a drive was initially presented for diagnosis and duly diagnosed with a blown PCB - the drive seemed completely dead and would not spin at all. As an additional test a new PCB was placed on the board so that the response of the heads could be tested. The result of this test was that the heads appeared to have been “blown” by a power surge through the drive.
Upon further discussion, with the client, it transpired that the IT dept had decided to remove the HDD from the laptop and as it was an IDE device mount it as an external storage device by using an IDE connector. Unfortunately they plugged the HDD to the connector “upside down” meaning that crucially the drive received a huge power spike through it when the connector was hooked up to a PC.
It appears that the lack of care taken by the IT dept has caused the drive far more problems that what was probably a simple case of “bad sectors” on a hard disk drive. The cost of a simple bad sectors recovery has now become a full HDD rebuild with the search now on for suitable parts - causing delay and additional costs to the School concerned.
Naturally the client is somewhat annoyed that his data, whilst probably still recoverable, is likely to cost much more and take longer in the recovery process.
Unfortunately most Data Recovery Companies will probably have their own tales of customer mishap or IT Technicians making their job more difficult through there well intentioned but often misinformed knowledge of hard disk drive technology.
So the moral of this is that whilst many people will look for a quick and cheap fix for their hard drive recovery problems, they really are best leaving it to the experts.
