External SSD & Solid State Hard Drives Not Detected

Solid state hard drives also suffer from errors and failure which cause them to not show up on their computers.

In many cases, external SSDs are much safer to use than traditional external hard drives. For example, when traveling, or using it for school, the lack of moving parts in an SSD make them perfect storage media.

Laptops with SSD’s are much more durable, and last longer than regular hard drives.


SSDs also fail to be detected on laptops

Users regularly experience these kinds of failures, but not because of the usual reasons. Laptops with traditional hard disks fail to be recognized due to mishandling by the user.

Many people mistake them for being more resilient and durable than they actually are. The main vulnerability is the hard drive, which can fail for even slight shock, or jolt to the computer it’s attached to.

SSDs however fail detection by a computer for different reasons. SSDs have no moving parts, and instead store data on NAND Flash chips.

Solid State Drives and NAND flash chips

These SSD’s come in many shapes, sizes, and interfaces these days. All of them are designed with the same basic architecture. And they all fail at one point or the other, which results in them not being detected any longer.

Solid state drives are comprised of an array of flash media chips in array. Data is communicated via a controller chip, which is responsible for processing  the encryption and error correction required for Flash media to read and write data.

This controller chip is one of the main reasons your SSD might not be recognized by your computer. When this chip gets corrupted it cannot do it’s job communicating between the chips and the interface,

When this happens the only way to get the data is with a system that can create a virtual controller, and access the data on the chips.
