Copy BTC Bitcoin Blockchain Using an External Hard Drive and Transfer to Another Computer

GAI: can you use an external hard drive to copy btc blockchain and transfer to another computer?

You can use an external hard drive to copy the Bitcoin blockchain and transfer it to another computer. You'll need to locate the data directory containing the blockchain database, then copy the entire directory to the external drive, and finally transfer the drive to the new computer. The data directory's default location is C:\Users\<YourUsername>\AppData\Roaming\Bitcoin on Windows. Make sure to shut down the Bitcoin Core wallet on both computers while copying the files to prevent data corruption, according to the Bitcoin Wiki. 

Here's a more detailed explanation:

Testing a 2 TB Hard Drive That Errored Out When Downloading the Bitcoin BlockChain

This disk failed in 2 attempts to download the BTC blockchain.  Ubuntu Linux was installed on this disk and it worked normally.  I still do not know why it would not work with Bitcoin core

Note:  What is "reindexing"

-reindex:

  • wipes the chainstate (the UTXO set)
  • wipes the block index (the database with information about which block is where on disk)
  • rebuilds the block index (by going over all blk*.dat files, and finding things in it that look like blocks)
  • rebuilds the chainstate (redoing all validation for blocks) based on the blocks now in the index

-reindex-chainstate:

  • wipes the chainstate
  • rebuilds the chainstate using the blocks in the index you had before

The latter should be strictly faster, as it does not need to rebuild the block index first. Perhaps the progress bar during reindex confuses you: that progress is only for the rebuilding of the index. The recreation of the chainstate happens after that rebuild is completed.

You should use -reindex only when you were running in pruning mode, or if you suspect the blocks on disk are actually corrupted. Otherwise, when you only suspect corruption of the chainstate (which is far more likely), use -reindex-chainstate
