Hello,
I have installed the new firmware (1.74) that was released, today. I can see the new SMB option to specify which version (Auto, SMB1, or SMB2) to use. I have tried selecting AUTO and SMB2.
When attempting connections, the problem issue remains exactly as previously described. The same temporary "work-around" (toggling the setting) still works until the next NAS reboot.
Best Regards,
Bob
This is for all of you who are having problems:
Since SMB 2.x works with the toggle until a reboot: then just don't reboot the nas or shut it off. That said, just don't do anything to the nas- that would make you need to restart it, or shut it off.
That's all that can be done right now (besides installing linux), until if/when Buffalo fixes the problem.
If something else on the nas doesn't work, to where you have to reboot. Then don't use that feature for now.
If backup jobs are throwing errors that can only be cleared with a reboot, then don't use them. Do manual backups from a pc for now.
If the sleep timers are acting up and not working right or causing loss of drive access, then don't use them for now.
NAS were meant to be left on 24/7 pretty much anyway. People shouldn't be rebooting their NAS daily, or even many times in a week- outside of seldom config changes.
These LS220D units were designed to be low power (The power supply is like 65W or so). At 10 cents per kilowatt- it's less than 5 bucks per month to leave it on 24/7.
Honestly, I don't know why some people are even using sleep timers with these, or shutting them off at all- to save what- 2 dollars? It is best to just leave the NAS on and let the drives spin. All the constant on/off just puts more wear and tear on the disk motors, with all the spin up and spin down. Any power saved is most likely a wash because the spin up eats up a bunch of power alone.

The only other suggestion I have - is to create a Virtual Machine and access the NAS with SMB 1.x, don't use the vm for anything else. If you're super concerned, then block the vm from accessing outside networks. If you want to make a VM, get Oracle VirtualBox (it is free) or something similar.
You could do the same with an old pc too. But don't use that pc for anything other than accessing the NAS. If it has windows firewall, then just block the system from accessing outside networks.
I have a low risk machine for this purpose (Win 10 with SMB 1.x enabled), as some of the older buffalo terastation units- don't even support SMB 2.x.
If your PCs are behind a firewall (which most of them are these days) You're probably not going to have SMB 1.x problems anyway. You just have to be cautious in what you are using and accessing outside of your local network. Use good judgement. Something has to be accessed outside the network, for SMB 1.x attacks to happen.
