If you are looking to repair a drive with this chip, keep these three rules in mind:
Installing firmware / modules
Use a diagnostic tool like ChipGenius to confirm your VID (Vendor ID) , PID (Product ID) , and specific Controller Part-Number .
AU87101A UFDisk: Comprehensive Guide to Alcor Micro USB 3.0 Controller Recovery and Management
: In extreme cases where the drive isn't detected at all, some hardware specialists briefly short-circuit specific pins on the NAND chip to force the AU87101A into a "test mode" so the software can see it.
Run the application and locate the . Ensure it specifically references Alcor Micro AU87101A (or a closely supported variant like AU6989SN/AU87100).

Set the scan level to or Full Scan . This ensures the utility tests every individual logic block.
Most users never see their USB controller, but the AU87101A became popular in technical circles for several reasons:
Splitting raw storage into a public standard drive and an encrypted, password-protected directory.
Once an Alcor controller is identified, specialized flashing applications are used to repair it. These applications operate beneath the standard partition layout of a standard operating system.
utility to clear the "Read-Only" attribute. It is safer and doesn't require third-party software.
A: No, "AU87101A UFDISK" specifically refers to USB flash drives. SD cards have different controllers (though they can also show generic errors like "Generic Storage Device").
