Hi
Does 8.0.0 have the ability to do fsck at boot? Or even badblocks?
After the flaky problems I'd had a few weeks ago, my LMS PCP finally
died yesterday and so I installed an Ubuntu VM so I could finally check
the sd card.
Code:
--------------------
sudo fsck -fv /dev/sdc2
fsck from util-linux 2.34
e2fsck 1.45.5 (07-Jan-2020)

Pass 2: Checking directory structure

But then I thought there may be an issue with the card itself so I found
the linux equivalent of chkdsk /r :
sudo badblocks -v /dev/sdc2
Checking blocks 0 to 31092735
Checking for bad blocks (read-only test): done
Pass completed, 0 bad blocks found. (0/0/0 errors)
After all that it complained at boot:
[ 83.647774] FAT-fs (mmcblk0p1): Volume was not properly unmounted.
Some data may be corrupt. Please run fsck.
I couldn't get fsck to work but then I realised that being FAT I could
use good old chkdsk from Windows and then it was fine, and everything
seems to be working again.
Is badblocks or similar available via PCP? It'd be really handy to do
all the sd-card diag stuff from PCP without having to pull the card and
use two different OS.
