Nick,

The vhd file is never mounted, unless you explicitly request for it (the Attach functionality).

No Save of Settings will take place at Shutdown, unless you confirm it upon asking of XXHighEnd (answer with No, and nothing happens (the vhd file never was mounted in such a situation).

Might you once in a while Save Settings to it, that is still harmless. It is not the OS. Nothing changes further but that small portion of the file (say 1000 bytes in the midst of 25 million). It could do something, very far sought.

Where it goes definitely wrong, is you using the files as the OS. I mean, you just told you do that by means of *not* booting from RAM. So now continuously things happen, and it happens fully automatically (like OSes are).
Whether you do that in MinOS or Normal OS is regardless, but doing it in Normal OS is more devastating because the OS is 10 time more "wild / active" in there.

So all cleared up.
Btw, on top of all I suggest that you even might leave it booted from the vhd for complete days - just because you did not care (springing from not understanding that this could happen).

The upside of it all is clear : very good that you posted about it because now you know. And others maybe too.
More upside for you as a person : I myself always suspected this (degradation) and when preparing a Mach III I always boot into normal OS quickly to wee whether it works (but the RAM OS Disk *has* to boot into that by default because of OS initial settings for people). Then boot into RAM OS, to see whether *that* works, quickly followed by booting into/from RAM where I finally am at ease because from there nothing can happen to the file. It is just impossible, as explained. And indeed, I won't even save settings so the disks (the full PCs) are as much equal to each other for everybody. So … you confirmed unintentionally that this matters indeed (and obviously this is nothing to explicitly test, so I never did that).

Last thing : Don't be hyped about this, please. It will be able to take a few boots from the vhd file (a 100 too). Nothing will noticeably degrade (says me). It starts to go wroing when you leave all unattended and let the OS do its thing when it notices all gets idle. This is how I referred to "a whole day". So that would really be bad in one go. This is still theory just the same, but it always has been and again, you seem to have proven just that.

Kind regards and happy listening !
Peter

Peter hi,

These are really interesting insights and guidance on what to do for the best usage, thank you. So get into RAM OS asap and only dip in and out of non-RAM boots quickly. I may not always able to do this for a while longer but for now I can always just restore the file when needed.

Thanks for the help and kind regards,

Nick.

I could postpone 2.11 for a while longer by putting in my ToDo a means to automate this copying …
Or maybe I can't keep this promise because I would let this go while booted from RAM, and the Mach II/III owners may find their Mach's running (too) hot during the process. I just don't know that. So mind you, as we know, copying the file to RAM takes a minute or two, but copying from disk to disk (SSD to SSD) will take (way) longer. Not CPU intensive at all, but … well, I just don't know.

Kind regards,
Peter

Peter,

If it helps copying the Vhd file from a usb 3 attached hard drive to my RAM OS SSD takes 3 - 4 mins for a 20Gb Vbh file whilst in WIN 8 BASE. I don't get any heat issues on my C621 PC whilst the copy takes place. A copy from SSD to the same SSD is going to be quicker.

My feeling is copying the file manually is straight forward. Knowing that this is an occational housekeeping activity and keeping an ear out for a gradually loss of SQ should be enough.

All code for looking forwards to 2.11 as soon as your ready  Wink
