Standard, low-end USB drives often use "downgraded" or "black" flash memory—chips that failed quality control for high-end devices but were repurposed for cheap drives. The AU87101A UFDisk, marketed as "Extra Quality," typically utilizes Grade A NAND flash memory. This ensures lower Bad Block rates, meaning the risk of data corruption over time is significantly reduced compared to generic market alternatives.
This classic Alcor controller bug occurs when the firmware’s block mapping table becomes corrupted. A standard format will not fix it. The Extra Quality utility performs a full chip reinitialization, rebuilding the LBA-to-physical block map correctly. au87101a ufdisk extra quality
