not sure, if this a KDE thing … (or Ubuntu?)
since two or three days, my KDE neon setup does file system checks before mounting any external USB disk device. this is not a big thing for smaller USB “sticks”/“pens”, but for a 4 TB disk with literally hundreds of thousands files in backups and similar, where this check takes about an hour.
Anyone with the same experience?
note: all these file systems have been cleanly unmounted beforehand.
tested with: two ext4 disks, one exfat pen.
I can’t verify, but this might be related and help you solve your problem:
The Disks & Devices widget now lets you mount a disk without checking for errors, or manually check for errors without mounting. These can be useful for huge disks full of stuff where you know everything is fine, which otherwise take a while to check for updates while mounting. (Bohdan Onofriichuk, link)
thx Philipp! i’ve really tried to find an appropriate bug report there, but failed.
the bug report has all the observations i made my self!
i’m normaly using the device widget (see screenshot) - sometimes Dolphin,
but with no different behavior.
what i have done so far … (and will copy it later to bug report)
attached the disk to another OS instance (ubuntu mint) and did a fs check there (without fixing!) with the expected result: no errors in fs
rebooted to neon and attached the disk the usual way .. Immediate mount!
rebooted again into neon, trying to mount again .. same result as before: looong check.
this all makes me thinking wild … is the problem a not marked clean superblock due to inproper unmounting?
edit: Linux Mint mounted the disk immediatly as neon did before. has the default action “Mount and Open” been changed lately and forces checking now everytime? (and therefore would ignore a clean flag?)
