I have an LS-ZH1.0T, connected to my wireless router. I have a laptop running Win7 x64. It worked fine for about 6 months or so, but now I'm having some strange problems.

After powering up, I can connect to the drive from my laptop, through Windows Explorer as a network drive. But, NAS Navigator cannot see it on the network. I can still access and transfer files on the drive through Windows fine. So I was fine with that, except then the drive keeps "shutting down" -- after a couple of minutes (of drive boot), the drive just stops responding, Windows cannot find it anymore either. All the drive lights are on and it's powered on, but just somehow there is no connection. If I power the drive off and on, the same process repeats.

I cannot do a firmware update either, because the update software cannot find the drive on the network either (even when Windows can).

Connecting the drive directly to the laptop using an Ethernet cable also produces the same results. So in short:
- Windows can find the drive, but NAS Navigator or firmware updater cannot find it.
- Even Windows loses the drive a few minutes after drive boot-up.

Any thoughts on what's going on, and how I can fix it?
Thanks.

Are you willing to share your firmware revision number with us,
or is it a secret?
Are you running the box in "on" mode or in "auto" mode?
Do you have root access to the box via Telnet or SSH?
If yes, run "top" after startup and look for suspicious processes
just before the "disappearance".
If not, try to connect via acp_commander to the box. Is this failing
too (just after boot and after "disappearance")?

Sorry for the delayed response. Was out of town and then hammered at work.

No secret, but how do I find that out? The only thing I can access are the drive folders via Windows Explorer, and that only for a couple of minutes.

Box is in "On" mode.

Not sure how to access via Telnet. I'm not very tech-savvy as you can probably guess.

Okay, I was able to access the drive via the browser.

Firmware: 1.34 (DTCP-IP:1.40-20110204)
Is there a way to update the firmware from the root access?

Restored drive to factory settings from root access, but no change.
NAS Navigator or firmware updater still cannot find drive on network.

Edit: even after the drive disappears from the network (cannot connect via Win Explorer or root access), it still shows up on my router's DHCP client list.

What about acp_commander? Can acp_commander see the box after
"disappearance"?

Never used acp_commander before, so let me know if I used it correctly. Ran this after the drive "disappeared" from the network (still shows on the router DHCP list):
Code:
java -jar acp_commander.jar -t 192.168.2.3 -f
Returned Found 0 linkstation(s).

You should try something like this:
Code:
java -jar acp_commander.jar -t 192.168.2.3 -ip 192.168.2.3 -pw password -c "ls /"

Replace the "password" with the password you use for user
admin and the web interface.
You ARE sure that 192.168.2.3 is the right IP address? (and
it is NOT automatically the right IP address because your
router displays this address in his DHCP leases; a router will
keep leases for days (3600 minutes))

The IP address is correct because I'm able to get root access via browser when the drive appears on the network.

Running acp_commander right after the drive boots works fine (with that IP address) -- it can find it on the network.
But once it disappears, acp_commander fails:
Code:
A SocketTimeoutException usually indicates bad firewall settings.
Check especially for *UDP* port 22936 and make sure that the connection to your LS is working.
ERROR: Exception: SocketTimeoutException (Receive timed out) [ACP Send/Receive (Packet:8020 = ACP_Discover)]
So at first read it looks like something with the firewall settings. I'm running AVG Internet Security. But to test, I turned off AVG firewall completely, and I still cannot find the drive on the network, either via Win Explorer, acp_commander, or NAS Navigator.

If you can connect via Telnet or SSH right after the boot, then do this
and run "top" to see which application is the last one running before
the LS disappears. Maybe this gives a hint.
