There's a similar thread in the system management section. My unit is brand new with 2 x Seagate 2TB drives in RAID1. It reboots itself often, only seems to happen when I have the DSM web interface open. Pretty poor for a brand new device, and seems fairly common.
I have seen the same issue. My new DS212j disk station keep reboot with "System booted up from an improper shutdown" once a day, which is quite annoying. What should I do, wait for a help test, or just return the damn unit.
I am wondering whether this is a software issue or a HW failure.
I just bought the DS212j and have had it running for about 3 days and am seeing the same thing multiple times a day. Sometimes the frequency is every 5 - 10 minutes. Usually it will not reboot if I don't use access it via the 5000 port.
What does not have an impact is whether the UPS, or external USB drive is connected.
Here is the message in the log after it reboots: "System booted up from an improper shutdown"
This has caused a format of a disk to fail and now the disk is unusable.
My impulse is to return the DS212j. I have looked through the forums and don't see any progress yet on this issue although many people are seeing it.
