I've build a new system running Slack64-current with a UEFI mb. Everything is running fine except that, even with normal shutdowns, the vfat partition (/dev/sda1) always has the dirty bit set on the next boot. In syslog it says that the vfat file system was not shut down properly and I should run fsck. When I do it says the dirty bit is set. I clear that but it returns on the next boot. Does anyone know a fix for this?

Where is the vfat partition placed on?

The first partition of the main disk - /dev/sda1

Can you post your setup?

Where are which data stored?

Partitioning and data on these partitions.

So I can better understand your problem.

OK here it is -
