Volume Copy - Load from file failed with file on share

[inexorabletash]

Running Ciderpress on a Windows VM, with an HDV file residing on a network share mounted on Z:, the "Load from file" functionality trying to write to a volume on a CF card hung Ciderpress with no progress then after several minutes crashed (Abort/Retry/Ignore) with some "file not found" error.

Copying the HDV file to a local drive and retrying worked.

The HDV file was created directly on the share from Ciderpress, so the other direction works.

(Apologies for the vague details.)

I'm guessing something went wrong with reading from the network drive, though I don't know why it would fail in CiderPress but work elsewhere. The disk image copy code does a bunch of retries on failure to deal with the case where you're reading from physical media with errors, so that's probably why it stalled out for so long.

Whatever the case, it should be putting up a polite "copy failed" message rather than crashing.

What version of Windows are you running in the VM?

Win7

I should note that the network share is not remote per se: it's provided by the physical machine hosting the VM. Still, there could be a timing issue, or something about how the name is processed.

At some point I'll try to repro, but the failing write effort had trashed the volume on the CF so I was just happy to have found the workaround. If I can get another CF card to play with I'll try again and see if I can find any other clues.

At one point I set up a VirtualBox VM with Win7 on it, but unfortunately I don't have a separate key (I'm running Win10 as an upgrade from Win7), so the key activation stuff gets cranky after 30 days. At least I got the system configured, which is more than I was able to do win WinXP.

The part I don't get is that, if it were going to fail anywhere, I would expect it to fail on the write-to-device side since that's where the "weird" stuff happens. The read side is just opening a file read-only.

Just to make sure we're on the same page, the case which failed for me was "read from HDV file on a share and write to physical CF card", using the "Load from file" option in the UI.

(To me, that would be a "write-to-device" operation, but that would contradict your summary....)

[fadden]

I think we're on the same page -- if the write-to-device side were fully broken, your subsequent attempt with a local copy of the file would have failed, which is why I'm assuming it's a read-side problem. But maybe that's a bad assumption, and it's the combination of "read from virtual network" and "write to physical device". Perhaps having a USB device open for writing interferes with the virtual network?
