After formatting a ssd , I can not add a new folder to it.
It it connected using a Star-Tech usb disk device for parallel & serial drives.
I formatted the complete drive as a partition with ext4, and separate partitions for backups & general saves.
When I try to add folders to it from file manager(dolphin), the ‘new folder’ option is greyed out.
Anyone know why? I gave not had this problem in the past.
Depended on the tool you used for partitioning, the owner of the partition is now root. This is a common “issue”. Change the ownership of the partition to the user or mount it available for your user.
It’s not so much the partitions, the folders created inside them. Create them as root, then change the ownership (and/or group) and set the permissions
It is the mount point, or else you would need to change the permission for each newly created directory (after you created it as root) seperately.
Depended on the use case, it makes sense to give the full ownership of a drive/partition/mount point to a particular user. That is why you can set the user flag when you mount the drive/partition via fstab. Or simply change the ownership of the mountpoint.
I don’t use Dolphin, so don’t know whether lack of being mounted would nevertheless leave an unmounted but available filesystem showing, thus disallowing putting anything on it. Did you remember to mount the new filesystem after formatting it?
