50% Logical Failure
The bits that comprise your essential information aren't arranged randomly. They're stored according to a precise scheme called a logical file system. If something stops your device from recording or erasing mid-operation, this scheme can become corrupted and unreadable even though the device's hardware still works.
30% Electronic Failure
The transistor-based flash cell memory that holds your data as bits relies on complex circuitry and delicate electronics. Habitual handling and regular use can jog connections loose or induce component failures through events like static discharge and environmental exposure.
15% Firmware Failure
Firmware tells your device how to use the complicated circuits that permit data storage. This low-level software is vital to basic operations, like finding and reading data. When firmware gets corrupted or lost, flash memory's contents may become inaccessible.
5% Deleted Failure
Sometimes you simply drag the wrong item to the trash or format the incorrect device. Although they're not as prevalent as other failure modes, deletions are just as serious, and they're hard to correct without proper expertise.
