Your SSD appears as 'SATAFIRM S11' with 8MB capacity instead of its real name and size.
SATAFIRM S11 is a notorious firmware bug affecting SSDs with certain Phison controllers. The drive's firmware crashes and it reverts to a basic state showing wrong identification and capacity. Your data is still in the NAND but inaccessible through normal means.
SATAFIRM S11: Critical Warnings
- ×Do not use manufacturer firmware update tools
- ×Do not use generic SSD repair utilities
- ×Do not initialize or format in Disk Management
- ×Do not use low-level format tools
- ×Do not attempt MPTool or similar utilities
Why this matters: The wrong repair attempt can permanently erase the drive's translation tables, making data recovery impossible. SATAFIRM S11 requires specialized handling.
Most Likely Causes
Firmware Crash
The SSD's firmware crashed due to bug, power failure, or corruption and entered safe mode.
Translation Table Loss
The drive lost its mapping tables and can't locate data in NAND.
Controller Malfunction
The Phison controller entered fail-safe mode after detecting errors.
Safe Diagnostic Checks
These checks are non-destructive and safe to perform. Follow them exactly as written.
