I/O error on WD_BLACK SN770M 2TB

marianomaldevida · October 13, 2025, 3:02pm

Hello. My usual sysctl config regarding dirty pages is as follows:

        "vm.dirty_bytes" = 48 * 1024 * 1024
        "vm.dirty_background_bytes" = 16 * 1024 * 1024

However, when I go higher than this, system shits itself and this is what I can find on journal:

I’ll try the stupid suggestions but this is not a good look. Now this happens regardless of buffer size.

Forgot to mention, this is shoved inside a Steam Deck.

For anyone stumbling upon this, if this happens to you, your SSD is defective.

I tried installing Windows to check out the Sandisk dashboard but after installation it would constantly BSOD with WHEA_UNCORRECTABLE_ERROR.

Try Windows 11 and use Seatools to check the SSD with SMART checks
