Step B: Setup (Press the "Setup" button)

Inside the setup dialog, configure these tabs: Cause: worn/damaged flash or overly aggressive auto trimming

• Cause: worn/damaged flash or overly aggressive auto trimming during low‑level format.
• Remedies: try different bad‑block strategy (reserve more spare blocks), different AlcorMP versions, and alternate firmware bins. If physical flash has many failed blocks, capacity loss may be permanent.

Scanning for and masking bad sectors, though this may result in a reduced total drive capacity after the repair.

Procedure:

1. Insert the USB drive into a USB 2.0 port (do not use USB 3.0 or hubs—they cause communication errors).
2. Click "Refresh" in AlcorMP. Your drive should appear as a blue or green line.

   Verification steps:

   1. Windows Explorer: Check capacity. It should match the original (e.g., 8GB, 16GB, 32GB). If it shows 4MB only, you forgot to uncheck "Format as CD-ROM."
   2. H2testw (Windows): Run a full write+verify test. This will confirm if the bad block re-mapping worked.
   3. CrystalDiskInfo: Check "USB" tab – Reallocated sector count should be zero.
