Re: Filesystem errors on armv7 -current

disk might still be corrupting

it could corrupt it's internal system sectors too

i have one like that

it corrupted even it's smart data and eventually failed to start and just clicks

i yet have to repair it which last time i checked costs 200 eur. apparently i had too old backup and i never got time to mirror it which was planned

now i mirror all my disks :)
