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.
Downloadable recovery software often seems like a good buy and can be quite reasonably priced but unfortunately it will not be able to help with as many hard disk problems and that is an important point to note. If you get it wrong you could lose your files forever!
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 may well have been in this particular scenario that the actual problem could have been no more a few bad sectors on the disk, however due to a certain level of incompetence within this department what originally was more than likely a simple job for a data professional turned into a much more costly full drive rebuild.
Many businesses need to get their data back as quickly as possibly so it is quite frustrating to have additional costs and additional downtime whilst you are waiting for data to be recovered
Sadly this is not an isolated case and data recovery companies the world over will have a whol;e collection of stories where simple recoveries were turned into data disasters by the DIY and have a go brigade
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.
