Au87101a Ufdisk Repack [2021] Official

: Support for newer NAND flash memory chips that weren't in the original release. Simplified Interface

Adjust settings in AlcorMP to lower the targeted capacity, or select "Force Capacity".

This is the industrial factory software. If ChipGenius reports the controller as AU87101A but the computer cannot read or write to the drive, you must use AlcorMP or ALCOR_MP_Product_Tool to complete a low-level format before using UFDisk to reposition or partition the drive. Finding the Correct Version

Working with the chip and UFDisk repack tools typically involves low-level USB flash drive maintenance, such as fixing "No Media" errors or creating custom partitions like CDFS. Overview of AU87101A and UFDisk au87101a ufdisk repack

The "Full Feature" versions of this repack typically include advanced tools for controller manipulation and firmware restoration:

Adjusting current limitations (e.g., configuring power draws like 200mA).

This controller is notable for being part of Alcor's USB 3.0 MP production tool family, which includes models such as AU89101, AU89102, AU89103, and AU87101. It is commonly found in budget-friendly or generic USB flash drives, and its widespread use means many users encounter driver issues, operational failures, and data corruption problems. : Support for newer NAND flash memory chips

Repacking performs a Low-Level Format. The mapping table is wiped; file carving is generally impossible after this process. This is a repair operation, not a data recovery operation.

In the 2005–2010 era, counterfeit 8GB drives were often 256MB AU87101A drives with hacked capacity. The repack can detect the real NAND size and restore the drive to its true capacity.

Download a hardware diagnostic tool like or Flash Drive Information Extractor (Innostor) from trusted repositories such as USBDev. If ChipGenius reports the controller as AU87101A but

Are you trying to or create a custom partition (like a secure or CD-ROM partition)? Do you have the Flash ID or VID/PID of your device yet?

These tools are destructive. They will erase every bit of data on the device during the "repack" or re-initialization process.

USBDev.ru Alcor page is the most reliable source for these niche repair tools.

Insert your corrupted USB drive into a native USB 2.0 port (USB 2.0 ports offer more stable low-level data transfers during controller firmware operations than USB 3.0+ ports).
