You're welcome, and you're close. You should be able to copy your Core data and Armory data over to the external drive. (Make sure they're copies!) Cash should do a large reorg and reset the blockchain, downloading only the data starting from the split. The Armory wallets will work as-is but you'll want to use copies since the wallets themselves (and the Armory DB) will split once you use the coins.
Are you running Armory and Core at the same time? What exactly is happening?
This is what I was running up until yesterday.
I have 2 SSD:s, one 500GB with Windows etc. installed and one 250 GB with both Armory and Bitcoin Core installed.
The bitcoin core folder is about 160 GB and the Armory folder is not even 100 MB. I don't know how this works because if I've understood it correctly the Armory folder should be about as large as the bitcoin core folder (and it would not fit in my 250 GB SSD if that were the case). But somehow this was how it was installed before (I followed a thread here on Bitcointalk to make it work).
What I had to do before to access my bitcoins and send them:
1. Start bitcoin core and let it sync.
2. Without closing bitcoin core, start Armory and let that finish. Then I would see my BTC balance in Armory and could send my bitcoins wherever I wanted.
If I did it in any other way (i.e. starting Armory without first having Bitcoin Core opened) I would not see my BTC balance in Armory and could not do anything.
Yesterday I installed the newest version of Armory and when I do the exact same thing Armory gets stuck at "Preparing Databases" and nothing seems to happen. In the right corner it says offline and I can't see my current balance.
So I don't really have alot of Armory data, should I have it somewhere? Should it be about the same size as the bitcoin data (i.e. approx 160 GB)? If then, should I maybe uninstall both Bitcoin core and Armory and then maybe install Bitcoin core on my 500 GB drive and only Armory on my 250 GB drive and let them sync? (I have a fairly fast computer, i7 quad core) and 1 Gbit/s internet, so it should not take more than a day or two, right? I also have a armory paper wallet, so I should be able to retrieve my BTC, right?
I have an external HDD with 320 GB (is that enough or do I need more space?), should I install Bitcoin ABC on that one and copy the bitcoin core blockchain files into that folder and then let it sync?
If I start Armory and path it to the bitcoin core, then I would see my BTC balance, right?
And if I start Armory and path it to Bitcoin ABC then I would see my BCH balance, right? (or am I completely lost now?)
(Since the fork I have sold approx half of my BTC, but none of my BCH, so I should have different amount of them).
Send the Bcash coins first. Cheaper fees, and they're the ones you want to move anyway.
Yes, will do when I get it to work
No clue. Presumably a bug in the logging code somewhere. Don't worry, goatpig isn't after your coins.
I can take a peek around the coins and see if I can figure out what's going on.
Okay thanks!
And thank you so much for your help! As you've probably understood by now, I'm quite the newbie and need very specific instructions
