Wednesday, 20 January 2016 00:00 Compact flash media is getting ever popular
With capacities increasing all the time, compact flash media is increasingly popular for data storage and we are seeing more for recovery!
Data recovery from compact flash...
We received a SanDisk 4Gb Compact Flash card where the JPG data had been deleted. This was exasperated by the client attempts to recover the data using free software. When data on SD cards is deleted, the information is still contained within the media, but the signs, which tell the system where they are located, are destroyed so that they do not recognize the fact that the data is still residing within the memory. These signs, called "pointers", are the indicators that data is present within the structure of the computer.
Deleted information can be recovered even when the pointers are erased, but the chances of success are massively eroded as time passes. As the compact flash writes new data, it will use free space and possibly overwrite stored data that has been previously marked for deletion.

Well they're not. There are plenty of components that can degrade and data recovery tools are still in their infancy!
Performing data recovery on solid-state drives
There are fewer data recovery tools generally available for solid-state devices; however we have been working on our own proprietary tools to overcome vendor specific solid-state drive designs and built-in encryption technologies. We can now boast data extraction tools for almost every solid-state controller. As a result, this last month has seen a record for successful solid-state drive data recoveries!
When they were originally introduced, solid state drives SSD were noticable for both speed and reliability. It was generally thought that because an SSD has no mechanical parts failure rates were negligable. Mechanical components cannot wearing down over time - as there are none! Nevertheless, they still have to worry about electronic components degrading. Capacitors, power supplies and controller chips are all prone to failure.
