Today, Nand Flash Tracer (NFT) has launched an updated version, delivering improved support for the full lineup of SanDisk、JmSD TF cards, memory cards, USB flash drives and SSDs.
Combining NFT’s previously released "block attribute configuration" feature and the newly launched native data analysis capability for SanDisk and JmSD devices,
NFT achieves an extremely high accuracy rate in parsing stored data. Manual adjustments to analysis results are generally unnecessary, delivering performance comparable to direct reading via the original manufacturer’s firmware.

Take SanDisk as an example:
all legacy software relies on LSN for data sorting. Due to the device’s storage strategy,
numerous data blocks in the chips share identical LSN values,
resulting in a large number of redundant backup blocks at the same logical location.
Users must manually verify and replace these blocks, which is extremely time-consuming.

With optimized algorithms in this NFT release, the tool directly reads the manufacturer’s table data to accurately locate the latest data blocks without manual intervention.
It truly enables one-click reconstruction to generate the image.







Ver3.26.10.12
1. Added manufacturer L2P table analysis for the full range of JmSD products and most SanDisk TF cards, UFDs and SSDs.
Operation steps:
a. Set block attributes — configure SLC blocks
b. Check the option for native L2P during sector sorting
NFT retains the legacy algorithm. If the native L2P lookup fails, uncheck this option to perform sector sorting using the old scheme.
2. Added sector sorting algorithm for PS2251-11/B.
3. Added LDPC error correction support for SM-SD.
4. Added LDPC error correction support for SM2259XT.
5. Fixed known bugs.

Hi, maybe start a thread under the "Software and hardware tools" section so all your updates can be in one place, not sprinkled through the flash section. doing great work, cheers

Yes, good idea!
