Gone were the days when a data recovery technician was just one of those very skilled IT blokes who does a monthly clean-up on your drive and writes back your files even when they are corrupt. The giant leaps and bounds which technology has taken now renders many things, not least of which experts, obsolete.
Modern times and technology requires a new breed of data recovery mechanic and a brand new class of clean rooms and tools. The increasing speeds at which modern hard drives spin and the ever denser data they contain implies a single head crash occurrence can affect far more gigabytes of data meaning larger profit losses to a business.
Hard drive sizes have also decreased in size dramatically which also makes mechanical recovery very difficult. Having a clean room means that a data recovery technician can open up a hard drive and replace any faulty parts without risk of dust getting on the hard drive platters. If this were to happen the heads on the hard drive would crash and it would cause platter damage. If the platters are marked you have lost your data essentially.
The once acceptable Class 100 Clean Room is now an outmoded thing and in 2004, the ISO scale became the standard. Some ISO systems now use laser to recognise the smallest particles of dust in a clean room.
Whereas a Class 100 Clean Room would suffice for the old 10mb to 250GB drives, an ISO-3 Clean Room is an absolute must for handling terabyte-drives and beyond. Already, research is in progress for drives which can hold petabytes of data. Data recovery labs have to keep up accordingly in order not to get left behind. Also with the drop in price of SSD drives and hybrid drives the investment in data recovery laboratories and equipment will be required as these new types of storage devices become increasingly popular over time.
