So, the flash memory wasn't built into the terminal, it was a 2.5-inch SSD drive that I yanked out of its plastic case to fit into the terminal's SATA slot.
Once unplugged it, I dumped the disk image using the dd command onto my computer, and then I worked on that image to recover the data.
No, half of the file system sectors were corrupted, but I was able to recover all my files. I'm still wondering how my files survived exactly on uncorrupted sectors....
The device was already protected by a UPS, but it failed and shut down.
I will no longer use this device, rather I will throw it away, because I will have no more use for it.
Unfortunately, I didn't have a backup, but I still managed to recover ALL the important files from this server, even with half of the file system sectors damaged. God, thank you. This is another lesson for the future to regularly make backups!
Unfortunately, I don't have another power supply with the same specifications on hand, as this thin client is the only Dell device in my home π. Replacing the motherboard is not cost-effective for such old hardware. I'll just buy a new thin client.
Alright, I'll give it a try. Thanks for the suggestion!
This is a thin client. It does not have a removable TPM module, so I cannot physically "pull out" that TPM.
Yes, this is exactly the Dell Wyse 5060 with an AMD GX-424CC processor. This thin client is already old, which is why I decided to purchase a newer one with a better processor.
Anyway, thank you for your analysis! I learned a lot of new things. I will try to get it running with your advice and let you know how it goes.
However, this server will probably no longer be needed, since half of its cores are damaged. Previously, its computing power was fully utilized (the load was almost always 4.0), and it handled my tasks very well with four cores. Therefore, I cannot imagine using it with only half of its power available π
Good point - I've fixed it
Yes. UEFI is working
Thanks!
