I'm trying to use DOpus 8 to restore some backup files from my PC to my Amiga over a local area network. It's worked fine before, but now I get the following error message and the copy doesn't work any more.
Copy Error - Directory Opus
An error occurred copying 'Games':
A device attached to the system is not functioning. (31)
Retry Skip Skip All Abort
The weird thing is, if I try and copy the files using Windows Explorer, the copy works just fine.
Can anybody suggest what might be going wrong and what I can do to fix it?
I haven't made any system changes on either machine that I can think would give me this error.
Unfortunately these reasons don't seem very plausible.
"The network link has gone off line for some reason. Bad network link?"
The LAN is set-up using a Netgear combined Firewall/Ethernet Switch/Router/Print Server (FR114P) and thus also provides very reliable internet/email access for 5+ machines (some via a WiFi Wireless Access Point and the FR114P) - including the PC in question and the Amiga. There is no way the network link for either machine would go down (even temporarily) without me knowing about it.
"AntiVirus - worm blocking ? Any use of Zone Alarm... "
The Amiga isn't using any AV or firewall s/w. The PC uses Blueyonder PCGuard AV/Firewall. The PC firewall is usually on as I sometimes have foreign machines connected to the LAN. The PCGuard firewall isn't very configurable so I have to turn it off to allow drive shares to be accessed across the LAN. It's been off when this error message comes up.
Like I said in my original post, Windows Explorer manages to do the copy just fine. The reason I'm not using Windows Explorer to do the entire copy operation is that the network link on the Amiga is not the speediest and a few Gb has already been copied and DOpus has the ability to skip over existing files (one of the reasons I bought it) while copying while Windows Explorer doesn't.
Is there any low level debug I can turn on to get under the root cause of this problem? It does seem to be DOpus specific. I've not seen anything remotely like it with any other software on either machine.
You could try running FileMon to see if Explorer and Opus are copying files in a different way.
It's quite possible that the Amiga-side driver only implements the subset of the required interface which (the current versions of) Explorer uses, since that would be good enough to get basic file copying via Explorer working, but Opus (and later versions of Explorer, and other programs) may rely on more parts of the interface which it doesn't support.
BTW, you're not running Win95 or WinNT4 on the PC side, are you?
Also, if the Amiga is running a port of Samba, check the log files that it is generating on the Amiga side. The error message you're seeing is one which happens when Samba decides there's a problem and gives up. The logs should say what it thinks the problem is if that's the case.
Some problem with the virtual file system you are using then I suggest. What are you running on the Amiga end - Amiga Forever explorer? This does not work correctly with Opus. It will work with drag and drop at times but not always. You'll have to use Windows Explorer if you want to transfer lots of data.
