: The computer recognizes the drive but shows 0 MB capacity. Write-Protection
Windows typically loads the standard automatically for this hardware. If the drive is corrupted or showing incorrect capacity, specialized Alcor Micro production tools are often used for recovery:
You can see your files but cannot delete or add new ones.
. These identifiers are critical for technicians attempting to recover data or repair "dead" flash drives that are no longer recognized by operating systems. Technical Specifications
For basic mass storage functionality, Windows typically uses its built‑in driver ( USBSTOR.SYS ). However, some system integrators and users may need the for full device support. usb device id vid 058f pid 1234 full
If the drive shows "No Media" or "0MB" capacity, users often look for specialized "Alcor MP" (Mass Production) tools specifically for the AU69xx controller to reflash or repair the drive.
Microsoft often distributes Alcor drivers through Windows Update.
Devices with this specific ID are typically classified as . Technical specifications often include: Controller Vendor : Alcor Micro. Speed : High Speed (USB 2.0). Common Controller Models : AU6986, AU6988, or AU6989SN.
Every USB device uses distinct values to register itself within an operating system: : The computer recognizes the drive but shows 0 MB capacity
Disclaimer: Repairing flash memory tools requires caution. Improper use of Alcor MP tools can permanently make the flash drive unusable.
When you extract information from diagnostic software like or Flash Drive Information Extractor , a corrupted device typically yields the following profile:
Locate and document the (e.g., AU6989SNHL) and the Flash ID (FID) string (e.g., 45 DE 94 82 76 56 ). Step 2: Download the Correct Alcor MPTool
Alternatively, use the Flash Drive Information Extractor tool. It will safely query the physical controller without writing to the disk, exposing the exact hardware configuration table and memory voltage profiles. Step-by-Step Repair Guide However, some system integrators and users may need
