When I started to record this video I noticed that Sandisk SD and microSD cards can sometimes get recognized as 30.6MB instead of their proper capacity (32GB, 64GB, 128GB, etc).
This is caused by the physical disconnection of the memory from the controller. On surface mount devices this problem can be addressed by reconnection of broken traces or solder joints. However, when we are dealing with a monolithic device, such as Sandisk SD and microSD cards - reconnection is nearly impossible. Sometimes traces can still be repaired as we did in this stunning work - • microsd with worst damage , but if the disconnection is not on the top level of the circuit, then it becomes very difficult. In such cases, we recover data from SD and microSD cards using a traditional "chip-off" recovery method. Traces corresponding to the NAND protocol on the card get physically wired up to a specialized adapter, which then gives us access to the physical image of the device. Once we obtain the physical image, correct as many bit errors as possible, and remove all data conversion mix elements, we create a logical image. The logical image gives us access to working files. So if you have a device that gets recognized with 30.6MB instead of the real size - then give us a call or contact us from our website.

30MB represents 15 of the disk packs that the Data General Nova used. So it could be useful, but that is presumably beside the point.

@pickelsvonbrine Год назад
@@Ualik123 You should see what it takes sometimes to get info on hard drive recovery. The data recovery industry is very tight lipped on hard earned knowledge or you pay thousands for a class. I recently needed to repair the firmware on a samsung drive. I spent about 6 ours looking for data and did not find what I needed. Ended having to reach out to some old contacts and pay a bit of money to have someone ELSE do it for me because they wouldn't tell me. Note, I still do data recovery on the side as a side gig but haven't been in a lab in a while.

developers of tools like Acelab and Rusolut offer schematics with continuous updates. That's one way of getting them. Tools like PC3000 flash are getting smarter to semi-automate the process. I just started to work on pinout developments. It's a tedious process :)

Did you also try the ISP mode instead of the SD mode, which you mentioned at the start of the video? Would that give the same result? Also, wouldn't raw recovery skip fragmented images?
@hddrecoveryservices
@hddrecoveryservices Год назад
fragmentation is not a big deal for memory cards and photos. ISP would not help here. The reason 30.6MB shows up is because controller does not see the NAND. ISP is still going to use controller to communicate with NAND.

Well, you started kinda like one of them fools, have to say I was wrong. You do know your shit :) (Do have an electronics and IT background myself for the record, but haven't dedicated myself too much to data recovery). Thanks for the video, seems I may need a couple tools sooner or later (though I will need to get stuff more for SAS disks...) If you have info on SAS data/disk recovery *for me most of them just want to make them visible again, data is only a concern in 1 disk truth be said (waited too long to swap a disk on a raidZ pool...)

There is not much play with SAS drives. Tools and capabilities are limited down to 2 tools PC3K SAS and Deepspar SAS imager.

@hddrecoveryservices
@hddrecoveryservices Год назад
If NAND is not connected to the controller, the device will fall into a "SAFE" mode, aka "ROM" mode. If this was a surface mount device - the issue could be solved much easier :)
