This is prob gonna be a difficult one, considering I’m a super noob.
But since I reinstalled my computer, I’m having trouble with my external hdd connected to my RP4.
First I could only read my files but couldn’t edit them through file sharing.
I tried some chmod’s, only to find out that I logged in with the wrong username in file sharing.
Somehow after this my external hdd doesn’t show up at all anymore and I also can’t log in as the root user in file sharing.
In drive manager it’s toggled as read only. I tried changing this in fstab, but automount keeps toggling it to read only.
Also with changing fstab and without opening drive manager, the external hdd still doesn’t show up.
If I connect my hdd to my computer directly, I can read, but that’s it.
Hope it’s a bit clear, but I have no clue what happened…
Try to run an file system check, fsck
Most likely there are some errors detected which force the partition to be mounted read-only to avoid further corruption.
Yes in case of filesystem errors, the drive is often automatically mounted read-only. But since you can still read files, you can copy/backup the partition to another drive at least. Copying will fail on the corrupted files as well of course, hence they will be missing, but very likely they are “only” a few system files, hence nothing that urgently needs to be backed up. If really personal data/settings are effected, you could have another look into /lost+found/ where files are parked which lost there inode, hence the their path, filename and attributes and such. The file size in such case might give a hint what it is and opening it with a related program could verify .
