Flash Memory Recovery USB/Flash Memory Recovery Tools One of the fastest expanding data storage sectors is that of devices employing solid state or ‘Flash’ Memory. These include USB flash drives, memory cards and the so-called Solid State Hard Drives. These have no moving parts and store user data directly onto one or more memory ‘chips’ in much the same way that a PC loads data into RAM. Such devices are not as susceptible to shock or vibration as conventional hard disk drives and their price, size, portability and ever expanding capacity are making them increasingly popular. Despite not suffering shock induced failures in the way hard disk drives do, flash devices are prone to their own types of failures. These include physical damage to the device itself, failure of the device/PC interface, logical corruption of the stored data and failures of the on-board controller chips. As well as handling the dataflows in and out of the device, the controllers play a crucial role in arranging the data within single memory chips or managing the distribution of larger files across multiple chips. The controllers also undertake ‘wear-levelling’ which means periodically moving data around within the device to optimise the performance of the memory chips. |
