Error 3: "Cannot format after double"
NAND flash has spare areas (over-provisioning) for wear leveling and bad block replacement—typically 7-20% of total capacity. The SData Tool V100 can reduce or eliminate this safety buffer, reallocating those physical blocks to the user-accessible area. A 128GB card might indeed have 140GB of raw NAND (the rest reserved for redundancy). By exposing the reserved space, the tool gives you "double" relative to the advertised capacity, but at the cost of drastically reduced lifespan and data integrity. sdata tool v100 double usb or sd card space exclusive
To understand the claim, one must distinguish between actual physical capacity and reported logical capacity. The SData Tool V100 does not magically add memory chips to your device. Instead, it uses three possible techniques, depending on the drive’s controller: Error 1: "Drive not compatible with Exclusive Mode"
