Some SM3271AC drives use fake capacity (e.g. 64GB from 8GB NAND). Test with H2testw or ChipGenius . If fake, only MPTool with capacity setting can fix (set to real size).

The device also includes advanced air quality monitoring, providing users with real-time data on their home's air quality. It can suggest improvements and even activate air purifiers or ventilation systems automatically to maintain a healthy indoor environment.

: Designed for "Chip-on-Board" (COB) designs, which allows for extremely thin (approx. 2.3mm) and waterproof devices. Performance and Reliability

Yes, but only if the controller is still functional. If the controller is fried (short circuit, no LED), recovery is nearly impossible because the NAND is encrypted or interleaved in a vendor-specific way. If it’s a firmware issue, . For data recovery, do NOT run MPTool. Instead, use DMDE or TestDisk on the raw drive before any flashing.
