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
: Some Alcor utilities allow creating a "Password Disk" or protected partitions using tools like iStar.exe , which restricts access unless a password is provided. Troubleshooting AU87101A Issues

Repairing or repacking an AU87101A device is not without danger. Using the wrong firmware version—often identified by the specific memory chip (e.g., SanDisk vs. Micron MLC) rather than just the controller—can lead to "bad blocks" or a complete "brick" of the device. Production utilities like the Alcor Micro MP or UFDisk must be meticulously matched to the controller's internal ID, which is often retrieved using diagnostic software like . Conclusion This is the industrial factory software
: The software identifies damaged memory cells and marks them as unusable, which is why a "repacked" drive might sometimes show a slightly lower storage capacity than its original rating. Using Repair Utilities
: Executing the production tool to rebuild the drive geometry. 2. Step 1: Identifying the Controller Hardware Troubleshooting AU87101A Issues is a USB 3
