Then we create a task with 1 physical chip (for CE0), set pins in the software and read it to the dump. To do this, we will set the Spider Board pin to CE0, while CE1 will stay inactive. We need to read the first part of the 128 GB monolith. So, all the preparation steps are completed, and we can move on to the program part. Put the monolith to the Spider Board pad with double-sided adhesive tape, connect the power wires and set all the pins according to the scheme. Let’s solder the power wires to the pins of the monolith according to the mSD Type 1 pinout scheme. Next, we need to strip the top layer of the monolith with a medium-hard fiberglass pencil.Īs we can see after stripping, we were right and the pinout of the monolith matches the Type 1 pinout scheme. Most likely, it corresponds with Type 1 pinout scheme from the monolith database in the Global Solution Center. So, let’s start working with the monolith. Because of the difference in the capacity of the parts, we will need to read each chip separately in different tasks to combine them into one later. What makes this monolith special is that it has two crystals, one of 128 GB and the other of 64 GB. Very capacious mSDs were put into top-end cameras and smartphones. In this article, we will look at SanDisk’s 200 GB solution.Īt one time, such drives were a technological breakthrough. 128 GB cases and above will be supported only by the translator. Service Area marker includes only 2 bytes without a bank marker, so the maximal number of sorted blocks is around 64 GB. Without a translator, it’s impossible to assemble an image with a Block Number if the case capacity is bigger than 64 GB. And again, the only way to recover it is to use a translator. Videos are also connected with the File System, and they are seriously fragmented between blocks and subblocks. For recovery of the F older Structure, in 90% of cases, we need a translator. That’s why when we apply image building with Block Number Type 1, we can get only a partial File System or even an empty image. The SanDisk controller is using subblocks for updating the file system. The only way to recover SLC cache is to use a translator. If the Flash drive becomes damaged during the writing process, most likely the File System and the latest recorded files will stay in SLC and their recovery will be impossible. The main idea is that with the SLC recording type, SanDisk is using around 20-30% of capacity for cache, which makes writing operations much faster than usual. On MLC/TLC memory, the controller writes down data in SLC mode, and then in the background transforms it into TLC/MLC. SanDisk is using SLC cache to store the latest recorded data. Usually, they have a lot of additional issues and features that are typical only for SanDisk modifications. Nowadays, SanDisk Flash drives are one of the most complicated cases. Such cards were released a few years ago and remained the mSD cards with the highest capacity for years until the 256 and 512 GB modifications replaced them. Today we are going to talk about the monolith cases produced by SanDisk, namely presented in the variations of 200 GB and 400 GB models. ![]()
