Permission to write in partition comes and goes

Since I upgraded to 22.04 from 20.04 I have problems mounting my second drive (only read). I've tried a lot of things, probably just to mess up things.

This is my /etc/fstab line:

LABEL=warehouse /mnt/warehouse auto rw,user,uid=1000,dmask=007,fmask=117,nosuid,nodev,nofail,x-gvfs-show 0 0

The fact is that since I changed the fstab, when I star my machine I can write in the drive, but afer a while, it changes to read only, and I can't write :(

I guess it's a problem of permissions, but I'm lost. I'm sure that if you wan't to help me you'll need more info, please ask whatever is relevant and I'll try to post it.

Thanks in advance!
