Ah, I did a ATE relay matrix once using a ISA board. Yep, I guess lots of shift registers and something to feed them.

The relay matrix being the current project.

Then you would not be dependent on the PC hardware. I also understand that it would be a large undertaking and would use your talent resources that should be spent on your products.

To give everyone an idea about my pain, there are on this machine two particular drivers for two different pieces of hardware. One won't install on anything after Windows 7. The other one requires windows 8.1 or 10. Fortunately the driver which requires windows 7 to install works just fine on the latter versions, it just won't install on them. I think it uses some functionality that isn't shipped with windows after 7. So a rebuild involves installing windows 7, installing this driver, and then upgrading to Windows 10, at which point everything else can get installed. A lot of the problem with much of the test equipment and physical machinery seems to be that it was designed with a specific age of computer in mind, and requires that system to run.

Unfortunately, due to the fact that these machines are not really 'servers' or 'workstations' but instead 'automation/test platforms', that is not really a possibility. The OS on these machines need direct access to the hardware. Often, the drivers/software are doing horrible things under the surface to windows to make it work. Adding a VM layer just isn't practical in this case. National Instruments describes it best: "NI hardware is not supported on VMs due to communication challenges and the possibility of incorrect data.Virtual machines generally cannot access the PCI bus. As such, PCI- and PCIe-based instruments are inherently incompatible with VMs, as are MXI connected PXI and PXIe chassis. Modern VMs often allow access to USB ports (known as USB pass-through). Given the hosted nature of the VM, the variable speed of data transfer associated with USB pass-through may cause errors when communicating with DAQ devices." My experience is that even pci or pcie passthrough which is supported in some VM's still isn't enough to permit this stuff to run reliably - it's a lot like the USB-passthrough issue described above. In my experience, failures are usually going to be software or disk, not the underlying hardware. If the underlying hardware fails, I realize that I'm stuck unless I have identical hardware. Knowing this, I often actually have an identical motherboard and/or server setting as part of the spares. And by identical, I mean exact version, often bought at the same time, or from the same batch.

Now if you can put all your stuff in a VM, you're set. Put it in Dropbox for a cheap smart (bit change only) backup.

I want to make sure I don't lose data. I have a couple of computers now which I really would hate to have to rebuild due to hardware failure. These are generally computers which run a machine, such as the automatic test system and the pick and place machine. These machines area all typically single-drive (non-mirrored) mostly off the shelf hardware running various versions of windows. I'd like to take a full image, and have at least a reasonable chance of putting it back on similar hardware (probably same motherboard, maybe different storage medium) and it just work. It used to be that the tool for this was Norton Ghost. But that's been discontinued (and I understand it was going downhill before that). So I'm looking for whatever the current modern version is. I know there's a few tools out there which do this (Macrium, Acronis, etc). But the reviews are all littered with failures. Unfortunately it's hard to tell how much of this is lack of clue and how much of this is broken software. I'm wondering if anyone has experience with using these modern equivalents? Preferably something which runs on a range of Windows OS'es, and can dump the image onto NAS. -- Forrest Christian CEO, PacketFlux Technologies, Inc.
