Hello Chris
New System76 Galago Pro laptop with Linux Mint 19.1, no windows with:
250G m2 SSD and 1TB drive:
Filesystem 1K-blocks Used Available Use% Mounted on
udev 8118408 0 8118408 0% /dev
tmpfs 1630180 1432 1628748 1% /run...
First I get a libparted warning: Error fsyncing/closing /dev/sdb: Input/output error.
Input/output error during read on /dev/sdb
When I first ran gparted sdb2 did not appear, only sdb1.
I have run a number of commands to try and solve this problem but to no avail. Please see attached file which also contains a print out of all error messages in dmesg.
