Because this is a firmware-level corruption rather than a hardware failure, specialized firmware repair tools (like PC-3000) are usually required to rebuild the mapping table and recover data. Drive Replacement:
Select the drive number corresponding to your "SATAFIRM S11" drive.
: The drive displays a capacity of 0B, 20MB, or 30MB instead of its original size.

Find the firmware binary file matching your NAND configuration determined in Step 1.
You will need to source specific utilities developed for this controller architecture:
. When the firmware detects critical metadata corruption or excessive NAND errors, it re-identifies itself to the BIOS as "SATAfirm S11" Because this is a firmware-level corruption rather than
The firmware plays a crucial role in managing the flash memory, controlling data transfer, and ensuring device compatibility.
The PS3111-S11 is a single-core, DRAM-less controller designed for 2.5-inch and mSATA SSDs. PHISON Electronics Corp. Performance
Firmware is not universal . You must get the update from your SSD’s brand (OEM), not directly from Phison. | Firmware string | Typical NAND | Improvements
⚠️ Incorrect firmware can brick the SSD permanently. Only attempt if you have a full backup and the correct .bin files.
Use chkdsk /f /r X: (replace X with your drive letter) to check for bad blocks saved by the new firmware.
First introduced around 2016, the Phison PS3111 (also known as the S11) is a dual-channel, DRAM-less SATA III 6Gbps SSD controller. Despite having only two channels—a departure from the four- or eight-channel designs found on higher-end models—the S11 delivers surprisingly competitive performance for its class.
The SSD is typically detected in BIOS as "SATAFIRM S11" instead of its actual brand name, and it often reports a near-zero or incorrect capacity (e.g., 20MB or 0GB).
