This is a follow-on from my question a few days back:
How can I stop constant HD journaling?
Setup is now:
- Windows 10 Pro on SSD
- Xubuntu 22.04 on SSD: partitioned as 1. /root (ext4) 2. /home (ext4) 3. /swap
- One internal SATA 2Tb HDD drive partitioned into two, both NTFS
- Boot is GPT
Problem/issue:
Running Windows I can access the Windows SSD partition, internal HDD and any USB-connected external hard drives or USB drives.
Running Xubuntu I can access the SSD partitions and I can mount the internal HDD partitions and external drives are automatically mounted.
I am transferring backed-up data from external HDs to the internal HDD using Thunar or Dolphin. Transfers are executed without issue. However, a short time later the HDD is subject to continual read or write access. I cannot identify what process this is but it seems to me to be indexing of some sort because eventually it stops.
The problem occurs when I unmount the HDD but the read/write disk access continues. If I shut down Xubuntu then restart the read/write access starts again, still with the HDD not showing as mounted. How can this happen?
Possibly associated with this is an error I received on one shutdown while access was occurring began:
GDBus.Error: freedesktop.DBus.Error.InvalidArgs: Type of message...
then it disappeared.
Main query is the accessing a drive that it not mounted. Does anyone have an idea of how this is possible? Is it a problem, aside from annoyance? Customer support from the computer manufacturer admitted they knew very little, 'nothing actually', about Linux.
