Reindexing after initial download of bitcoin core I recently downloaded bitcoin core. Took about 1+ week to download 80%. One day I checked, it got an error message. When I closed and reopened the bitcoin core, it started reindexing. Any idea how long this will take? Turned it off after a day of "calculating indexing time". Was trying to mine low to no fee transactions as I start getting into bitcoin.

Well, I figured this one out. Running a full node on my other computer with internal hard drive is much quicker.

Believe the original problem that I had was that I downloaded the application on my internal hard drive but saved the blockchain itself on an wireless external drive. Having the external drive disconnected even once I think would cause some issue.

Given the size of the blockchain, not sure what the plan is once it reaches 1TB?
