TerraMaster Forum

Good day all,
I had a TerraMaster f2-212 or something like that, well the unit just died on me I had moved over a few folders to it so I could reformat my PC I had not gotten to the TNAS to put local copies back on my computer yet. The TNAS unit completely failed, no boot, no initializing when I did get it to boot. Just a brick. I now have a newer model and I want to get the data off my drives, the new unit wants to format the drives. I have a decent USB HDD reader, the computer recognizes a drive has been seated, but not that it's actually there. Nothing in disk management, under my computer in explorer, nothing. I looked and it seems that the TNAS I had used TOS 5 or TOS5.1 as it's operating system. Is there any way I can get those folders? (I know I should have redundant backups but I just started my home network setup and hadn't gotten very far yet.)

Thanks for any and all response's

OS: Windows 11 Professional.
TNAS: f2-212 (after researching I verified model)
Custom PC.

Hello, what model is your newly purchased NAS? If there are extra slots, you can use another hard drive to install the system. After installing the system, insert the old hard drive to read the data.

It has 2 slots, I did not think of this... Thank you I will try.
