Topic: Setting up a Node - fatal internal error (Read 206 times)

USB drive has bad blocks. Will replace the drives.

Cheers

Thank you. I've deleted the data as per suggestion and restarted but the error happens again - much quicker this time.

I'm currently running chkdsk on the external USB drives but suspect you're correct. If it's a hardware fault I'll get it sorted asap as I want a node up and running.

Cheers

Seems the Bitcoin Core is having trouble reading a particular block from your drive... possibly a corrupted database file, or your disk might be faulty.

Delete the blocks folder from here: F:\Program Files (x86)\New folder\Bitcoin\data

And try starting Bitcoin Core again... if you get the same issue occurring, it is most likely going to be a hardware fault.

Complete noob here wanting to run a full node but having errors.

Bitcoin Core: v0.151
Operating System: Windows 7 Ultimate 64bit
PC: Intel Core2Duo 2Ghz, 4Gb RAM, C:\ 14.3Gb free, D:\ 255Gb free, E:\ (DVDROM), F:\ 353Gb free (External USB - Bitcoin Core and data are installed on this drive), G:\ 809Gb free (External USB drive)
Problem: dialogue box "Error: A fatal error occurred, see debug.log for details"

This error came up one first run of the software when synching the blockchain. It has come up again after re-booting and restarting.

First run debug.log from line above the error:
