The three day Flash training offered by ACE Lab is a must in this very complex business of NAND device data recovery. The instructors know their product because they use it on a daily basis. In three days they cover the theory of NAND data storage and retrieval, key indicators of the algorithms used by the controllers. Then they provide practical exercises where you can apply what is learned and receive immediate feedback on problem areas experienced. The training is intense but well worth the trip.
The 2 day advanced HDD Course is an excellent course to attend. They covered Seagate drives and how to restore them to functional condition so data can be recovered. If one want to know how to become a better data recovery engineer, then this course is for them. I have a better understanding of Seagate drives, their architecture and data recovery methods.
