Fake flash microSD cards can be made usable by adjusting partition table, ongoing tests show
↗
An ongoing independent test of microSD cards examines capacity, performance, and endurance, including how fake flash cards can be repurposed by adjusting their partition tables.
For engineers using microSD cards in embedded systems or single-board computers, the distinction between advertised and physical capacity is critical. The article's method for detecting fake flash and adjusting partitions offers a way to salvage cheap cards, but the ongoing endurance tests will reveal whether they are reliable for long-term writes.

The test project began in July 2023 and covers name-brand and off-brand microSD cards, including fake flash.
Fake flash cards advertise more capacity than they physically have, but can be used if the partition table is adjusted to the true size.
The article evaluates authenticity, performance, and endurance, with results updated as testing continues.
