Greetings! All help is greatly appreciated.
I store Bitcoin Core wallet on an external hard drive. All the files related to the wallet live on the hard drive (as far as I know). Whenever I need for it to catch up on transactions I connect it to one of my computers (always same one) and it updates.
Sequence of events:
Bitcoin Core wallet lives on an external hard drive with no issues for a while.
For an unrelated reason I reinstall Windows on the computer. (Including this in the timeline, so you understand the computer is in a factory reset condition right now)
I connect the Bitcoin Core hard drive to that computer as usual and run the wallet. It starts running as brand new (inquires if the program is being run for the first time and offers to choose where to store the loaded data, starts to catch up from the beginning). No transactions reflected. No addresses stored. I don't know how to properly open the wallet.dat.
I run a Litecoin Core from same external hard drive. Also shows the window as if the program run for the first time. I set the directory to the same folder it used to be (within the litecoin wallet on the same external hard drive). Happy ending, wallet catches up, all funds there.
I haven't let the Bitcoin Core catch up yet. Should I? All advice greatly appreciated, I am still in the middle of my education.
Here is a case that I found to be closest to mine. Except there isn't a reason why my wallet.dat would be reset (because the wallet lived on an external hard drive, not connected to computer).
