It is natural that we should attempt to avoid spending unnecessary money, but despite the many warnings and blog articles detailing how a DIY data recovery has gone wrong, there are many people willing to give it try. There are many articles and videos on the internet providing details of quick fixes that have resolved a problem, seducing people into giving them a try without thinking through the consequences of the damage it may cause if they fail. The value and importance of the data stored on the device should always be considered. We always recommend sending the storage device for professional data recovery, rather than making what may be ill fated attempt at DIY data recovery.
There are many examples, from freezing the hard disk drive, tapping it through to twisting it forcefully, but these are unlikely to work and if they do are very short terms fixes. These are more likely to cause additional damage, resolve the problem and in the case of freezing the hard drive it often leads to a total loss of data.
Another possibility is swapping components of the drive for donor parts, from the controller board right through to changing the read/write head stack. Such procedures are extremely complex and should only be undertaken by a professional engineer in a clean environment. Removing the top of the drive, especially in a normal office or home environment will in the vast majority of cases render the data completely inaccessible.
It is not just hard disk drives where we see DIY data recovery attempted. USB sticks are easily damaged and appear to be simple to fix when they have been broken. In most cases this is not so, even for a skilled engineer, but those with moderate skills a lot of damage can done by the injudicious use of a soldering iron.
