Upon transferring some files across server disks I lost connection and the server crashed. Plugging in a Screen showed no response at all. I had to reset the Server, which then boots normally. At first I thought it was Samba, but I verified today that it also happens when issuing move commands via SSH. I'm running Ubuntu Server (x64) off a stick on an Asus C60M-I with 2GB non-ECC memory. I did recently switch the Realtek Ethernet drivers (r8168) from the default ones. (r8169) But I doubt that that has anything to do with it.
Before this all started, SMB transfers would start fast between server drives (30-38MB/sec, one drive is SATA, the other is mentioned below is eSATA), but would then slow down to an unreasonable speed, at which point I canceled the transfer.
After reboot it also appears that I'm getting permission denied errors on all my disks. (when non root) Deluge also cannot write files anymore because of this even tough the mount and all contents are owned by nobody with full access. (ext4)

Here is the Syslog, which seems to point the finger at the first and only partition (ext4) on sdd:
Then I've checked this drive with SmartMonTools which aside from having had a high temperature at one point (still within the max of 60°C), seems to be doing ok:
I'm pretty new at this.
