USB flash NAND storage devices, or memory sticks as most people call them are very popular today due to their low cost and reasonable storage capacities of up to 16Gb.
Very easy to use simply straight out of the box so to speak, they offer a quick and portable way of storing your data such as photo’s, music and video data, and because they are small you can carry them around with you and transfer your data from one system to another.
Typical failures of this device though are snapped or broken USB ports, this usually occurs because the memory stick is left in the computer and gets accidentally knocked, thus damaging the connector, repairs to this area often yield a full recovery and requires a hot air gun and decent soldering skills.
Further failures to this device can be SMC failure of the crystal or other components such as resistors or capacitors, again rework via a hot air gun, a digital multimeter and sometimes a oscilloscope can repair such failures, however sometimes the actual controller itself will fail, this is not a repairable item really, unless you have the skills to unsolder and rework 100 pin quad flat pack or similar components.
The next stage from this is to actualy read the flash NAND directly and then rebuild the file system and folder structure, this is VERY complex and requires skill and knowledge at several levels, firstly there are many different types of controlers, also how many actual flash chips are there?, then the file system reconstruction stage.
Often memory stick data recovery can be more complex than hard drive recovery for the above reasons, and as such can be very labour intensive.
Newer SSD storage devices utilize a similar technology although they are on a larger scale in terms of size, chip count, and resources required.
Most computer users would conclude that because the solid state technology has no moving parts their data is safe and secure, well it is until one of the above issues occurs, so to be safe why not duplicate the data? also make sure that the pen drive has a unique memorable password to safeguard your precious data.
