My Snow Problems

Thanks Grant

I will certainly try to find the adapter you suggested .... however what I am trying to do is using Snow Leopard with FCP7 and I didn't make this clear enough probably.

I want to reuse Snow Leopard as Final Cut Pro X doesn't read the previous versions files, and Snow Leopard was the latest OSX system working properly with FCP7

Booting from Snow Leopard however I get a message telling me: you need to boot from Lion to see this disk. The disk I have is a EL Capitan disk with several files I used and not to be able to see them makes me wonder.

Both drives are formatted with GUID partitions and with the extended format.

This only happens if I boot from Snow Leopard, which read Yosemite disks quite properly, therefore I don't undertand what is the problem, but is really annoying. I could certainly buy another external drive and copy every file I have in the El Capitan drive as the are standard Quicktime ProRes Files, readable in SL

I wonder if this is a problem in my already old Snow Leopard installer disk, or something else

Since you mention a problem with El Capitan using two different video slot, is the same problem happening with SL?

Thanks for your patience and regards

Heelo Grant ... sorry it took me awhile to do the screenshot as it only lasts a short amount of time and I had to be quick as I had to disable everything else to appear at startup first, and "LEARN" the best way to get this screenshot.

This message is the very first to appear on the screen just after booting

Here it is finally

I think it will be useful to boot pressing CMD V but I am not experienced enough to save it or I dont know if it goes to the log folder

However indeed the El Capitan disks works just file and all files are still there but I need to boot at least with Mountain Lion to see the disk on the finder

Also is there a USB3 card you recommend for Snow Leopard? My Sonnet Card only supports OSX after Mountain Lion, but again most files are on my USB3 external disk, I can use them of course as my Mac Pro has several ports, but I loose the speed

I bought a Caldigit with Snow leopard drivers, but it's quite buggy and often the disks go to a "sleep! mode

As the content of the files is my video clips I worry the disk gets damaged and it will be a total disaster.

Any Ideas?

Thanks

I googled with not much look.

AS I moved from Snow directly to Mavericks I don't know much about Mountain Lion. Does FCP7 performs well with this system? If the answer is Yes all my problems will go away although I will not be able to use the software I personally did using Applescript as most commands were already deprecated in Mavericks

Any Ideas?

Thanks

Yes it is ... is 3 GB

Thanks Again Grant,

well before installing anything I erased with 1 pass the whole thing, so, as I installed EL Capitan the drive should have been totally empty.

I am not too technical and I don't know exactly what "coreStorage Volume and coreStorage Group" are.

In my opinion, but is only a personal thought, Snow is too old, and probably other users don't have a set up as mine and maybe they never needed to use anything EL Capitan, booting with SL. But is only a thought probably untrue,

If I restart the MACPRO in a Target mode, my PowerBook with a working Snow Leopard boot, will see the disk without problems.

I wonder if the PCI cards are also creating this problem .... I don't know.

Still I wonder if you could suggest a graphic card I could use to increase the Speed with Snow Leopard and a USB3 card, as the one I have with SL drivers is buggy and puts the disks suddently in pause

I fear loosing my film takes if the Hard Drives resents these sudden stops while working

Regards and thanks again

As I said earlier I could Boot using cmdV but I dont dont know if is possible or how save this file to disk

Regards again
