My computer suddenly stopped detecting my SATA SSD. I removed it and connected it to a USB-to-SATA adapter on a Linux laptop, but it still wasn't recognized. While connected, the drive or adapter began making a buzzing sound. The SSD looks normal externally, and I don't have equipment to measure its power draw. I understand that the drive may have failed, but what components or electrical problems could cause this, and what might be producing the noise?

The main practical lesson is to replace it and restore from backups rather than keep testing it. Keeping some free space can help performance and wear leveling, but running below a particular percentage does not normally make an SSD suddenly buzz or disappear. Important data should follow a proper backup strategy with more than one copy.
A failed SSD can result from many things: defective NAND or controller chips, worn-out power regulation components, solder or PCB faults, overheating, or simply an early component failure. These problems often leave no visible marks. If the drive is not detected through either SATA or USB, the controller or power circuitry may have failed rather than just the stored data becoming corrupted.
SSDs have no motors or other moving parts, so the buzzing probably isn’t coming from the storage itself. It may be coil whine from the USB-to-SATA adapter or its power circuitry, or it could indicate a shorted or failing component drawing power abnormally. Stop connecting it if the adapter or drive gets hot, since repeated attempts could worsen the damage.
The brand alone doesn’t make a drive immune to failure. If the noise only occurs through the USB adapter, try a different known-good adapter or cable once to rule out the adapter itself. If the SSD causes buzzing across multiple setups, treat it as an electrical fault and avoid powering it further; professional data recovery may be the only option if the data is important.
Even relatively new drives can fail unexpectedly, including during normal use. Age and the amount of free space are worth considering, but neither guarantees reliability or explains every failure.
