Oh and I am ordering myself a nice big SSD to put this on later.
Newegg running a good deal on this -

Also what version of bitcoin are you using? 0.12 and above seems a lot more robust. (or I've been lucky not to have had such problems since).

Thanks! You have been a great help!

I'll figure that command out.

Downloading chain now, AGAIN, onto SSD....sigh

How do I tell the core what path to use if I move over the files?

To get it on SSD I will need to start fresh and tell it /appdata/blah blah blah

But if I move the files to c:/users/appdata how do I tell the core that?

Use -datadir command line option. e.g. bitcoin-qt -datadir=D:\Blockchain\BTC - or there is a registry setting you can change, but I'm not using windows right now to look for you.

NOTE: The -datadir command line option overrides the registry setting. You could run regedit and look for it. Something like HKEY_USERS_SOFTWARE/BitcoinCore or something like that. Look for a string which relates to the data directory.

I have a 120gb SSD I suppose I could empty. Guess i will try. You are correct the 1 TB HD is a WD mechanical

Blockchain is about that size, so not an option I suppose. Unfortunately bitcoin database resilience is not the best. Could always use it to get a head start, close bitcoin cleanly, then copy the blockchain over to the mechanical HD and finish the job.

Sounds like your index got corrupted during the unexpected shutdown. The reindex is not downloading all the blocks again, it is just reindexing them. After experiencing this issue a few times on a mechanical hard drive, it may will have been faster just to download again rather than reindex!

Looking at the download times, it sounds like you have a mechanical hard disk, and that is your bottleneck. It really is that bad.

Consider getting an SSD to store the blockchain on. Then you will be CPU bound, probably will be done in around 24 hours.

Ok last week I lost my HD and had to rebuild the BTC chain. After 24 hours a days and 7 DAYS LATER (YES 7 F&^%$ING DAYS) of solid downloading 8 years of this thing from scratch I got to 36 hours left and the damn PC shut down.

No way am I doing another 7 days !!!

Gotta be a way to recover?

I got some error message about something and the core wouldnt load at all.
I executed the --reindex command and realized this was a restart.

All my blocks and chain are there from the last 7 days.

Oh and if your wondering, 8 core cpu, dedicated 30 mb Comcast connection, AV off, Indexing off, Onedrive off, everything off.
Tons of space on 1 TB drive and plenty of free RAM.

Please someone give me some ideas so I dont have to go 7 days again of no PC. I cant use it while this thing is downloading so I don't risk a crash (funny huh, it crashed anyways)

Thanks
