No name 8GB USB Stick Repair, with AU6989SNL/AU6989SN-GTA Controller

I received a Red no-name 8GB USB stick with two partitions that cannot be combined because one of the partitions was write-protected. Neither Partition Master nor MiniTool Partition Wizard Professional could merge them because one partition was write-protected.

I used ChipGenius to extract the info about this usb:

Protocal Version: USB 2.00
Current Speed: High Speed
Max Current: 200mA

USB Device ID: VID = 058F PID = 6387
Serial Number: 86BECCFEAADE07182290

Device Vendor: Generic
Device Name: Mass Storage
Device Revision: 0101

Manufacturer: Generic/Generic
Product Model: Flash Disk/Flash Disk
Product Revision: 8.08/8.09

Controller Vendor: Alcor Micro
Controller Part-Number: AU6989SNL/AU6989SN-GTA [EF01] - F/W FA00
Flash ID code:      ECDE94F3 - Samsung - 1CE/Single Channel [MLC] -> Total Capacity = 8GB

I accessed usbdev.ru and, after multiple attempts, identified the appropriate ALCOR MP utility to recover the USB drive. The required version is ALCOR MP v16.06.07.00, available for download at the provided link.

After data recovery, the USB stick’s capacity is reduced to 6.6GB, notably lower than the original size due to the high number of bad blocks detected during recovery.
