Subject: LDPC NAND recovery in practice: real cases, not announcements Hi all, I’d like to introduce our lab, RATUJ-DANE (Poland). For the past months we’ve been focused on one thing: monolith and chip-off NAND recovery on devices that use LDPC, where classic hard-decision correction is no longer enough. We work on our own hardware, designed specifically for this purpose. It reads at the raw, pre-ECC bit level with soft-decision LDPC decoding. We don’t rely on generic ReadRetry tables. For each NAND family we re-develop ReadRetry from scratch so that it works as effectively as possible together with LDPC correction. Highlights: full LDPC recovery from real customer devices: USB drives, microSD cards, monoliths typically well below 1% of pages left uncorrectable after ECC, often a fraction of a per mille practically 100% of data recovered intact, including video files on SanDisk media recovery of usable data corrected read speed of 12–20MB/s besides BCH and LDPC, we have reverse engineered a third ECC scheme used in current NAND devices Our completed cases are posted on our Facebook page as they happen. What we offer We take on difficult NAND flash cases: LDPC controllers, high bit-error dumps, damaged dies, monoliths. If you have a case that’s stuck at “it’s LDPC, can’t be done yet”, send it to us. Service centers and fellow labs get 50% off the first case. This offer is for B2B only, not for individual customers.
