NVME problem

[chaoskampf]

I've installed (as described in wiki) Intel SSD 6 660p Series 1024Gb (SSDPEKNW010T8X1). Booted several times. Everything was fine. But next day after booting pbp there is no NVME disk at all (no disk in fdisk and lsblk output). Maybe I can check smth else to debug this problem if disk is not dead? Thanks in advance!

Did you have to fold the ribbon cable from the main board to the adapter, at all? Pinches on the ribbon cable can cause it to disappear.

I was able to do this without folding the ribbon. It looks like ok. Just ordered nvme to usb adapter to check if the ssd is broken.

UPD1:
After I secured the ribbon with tape I was able to get nvme work after boot once. But after next reboot it is not available anymore.

UPD2:
Smth wired. The nvme seems to work only after poweroff but not after reboot.

UPD3:
After adding the following line to crontab issue is probably solved (because save switch is not supported).

Code:

sudo nvme set-feature /dev/nvme0 -f 2 -v 2

The battery was lower 15% today for the first time after I've installed the ssd.
