Additional Information (if applicable)
- Software title | (EG: Nextcloud)
not really a software title issue imho, but e.g. Nextcloud, Urbackup, Syncthing - Was the software title installed freshly or updated/migrated?
Yes, Urbackup - Can this issue be replicated on a fresh installation of DietPi?
Well - not really…

Steps to reproduce
- Start reading writing anything to or from an external Western Digital HDD
Expected behaviour
- Write read and write speeds of ~70-100 MB/s of sequential read/write speed
Actual behaviour
-2-4 MB/s of sequential write speed
Extra details
-I have the exact same issue on 3 identical dietpi installations which are almost 100% identical in terms of hard- and software. 2 of them are running at my sister-in-law’s place one is running in my own home. The issue is not persistent. Sometimes i recovers for a couple of minutes.
I had the filesystem unmounted and checked - no issues. It contains the dietpi_userdata because it has to. I am using nextcloud and nextcloud stores its userdata underneath dietpi_userdata. And since i dont want to use a terabyte SD card… I checked the filesystem by shutting the system down, plugged the hdd into another server, mounted it and performed the check.
I can confirm that it ran quite fine on the other server. It seemed also to work fine when forcibly unmounting the drive and mounting it to a different mount point.
I am running into issues like these every now and then. E.g. i have a NUC9i9QNX here which has plenty of USB ports. I added a lot of USB 3.5 inch drives to it (with additional PSUs). And all of them work fine most of the time… Like 150-300 MB/s R/W speeds. Only one drive does 20-30 MB/s read speeds. While the rest if working fine. Of course i unmounted and checked the drive, used another USB Port etc… none of that worked. Only changing the mountpoint seems to solve it for a while. However - having to work with 2-4 MB/s R/W speeds at the above mentioned raspi installation is a showstopper. Please help me mitigating it.
[EDIT] Forgot to mention: i already omitted the the external harddrive from /etc/fstab and added it manually again (without using dietpi-drive_manager). That also changed nothing [/EDIT]
