Today we got a counterfeited PNY Elite-X 128GB SD in for data recovery. When we read the card it showed as 128GB filled with 0xFF’s. At first we thought maybe the FTL (Flash Translation Layer) was corrupted and that by…
Most silicon motion controllers use the same spare area data structure. I ran into a 32GB Lexar Professional 1000x using a different data structure. The value in block function ranged from 0x90 to 0x9F. Unknown contained 0xEF. LBN (Logical Block…
Verbatim Store 'N Go 8GB with a Phison PS2251-68-5 controller. Off-chip recovery with 15 pages per sector and bad byte columns — wrote our own tooling to strip the columns, correct bit errors, and reassemble from spare area markers.
Industrial 16GB Extreme CompactFlash card with a dead Phison PS3006-T controller. Read the NAND directly and used debug markers in the spare area to reassemble the image — 100% recovered.
A SanDisk Ultra Flair 1TB became the first 1-terabyte flash drive to come through our lab, and we recovered every byte using advanced read-retry algorithms.
SanDisk Cruzer Glide 16GB (SDCZ60-016G) with a broken USB connector — circuit board repaired, all data recovered. Notably, SanDisk used a refurbished 32GB NAND chip with 2:1 overprovisioning to sell the drive as 16GB.
SanDisk Cruzer Glide 128GB (SDCZ60-128G) with severe NAND Vt drift causing uncorrectable ECC failures. Recovered 100% via Vref calibration and multi-read soft-decision combining.
Sadly we were only able to get a partial raw recovery in this case which is typical, but usually we're able to get a better recovery by modifying block numbers however the block number markers made no sense, only high…
We have a high resolution X-Ray machine now for identifying internal faults inside IC's. For example this Lexar Monolithic Flash Drive (FC1178 Based) had a short at the controller preventing us from reading the flash memory chip using standard pin-out…
