So I pressed reset settings and now the blockchain is loading again...

(Using Bitcoin Core,) I had previously downloaded it in full and my wallet was synced, after I did this it started loading from the start. Any way to fix this? I don't want to wait again for the whole blockchain since I downloaded once laready... I have a somehwat slow connection and it could take up to a week.

Did you try restarting Bitcoin? I'd guess that it forgot where your block database is. It's probably still on disk somewhere.

I did, and yes it is. How to I make it detect where this folder is?

"reset settings"?

I doubt you are redownloading, check your bandwith useage. Its most likely doing a rescan of the existing data. A single core with 1 Ghz and a slow 5400 RPM HDD will need ~24 hours for that IIRC.

Scratch that, it's "reset options" in the US version. That's the button I pressed.

I don't really know why that would happen, but I'd try give this a try: Shut down Bitcoin, then find your data directory and rename bitcoin.conf to bitcoin.old.conf. (If it turns out that your data directory is not in the place listed on the wiki article, then that in itself is probably the problem.)

I wonder if this could be a bug in Bitcoin Core. Are you doing anything unusual? Are you using the Bitcoin Core release from bitcoin.org? What OS?

I doubt that these settings are stored in the bitcoin.conf as this file is not existant by default and has to be created by the user.

I did a bit of digging in the source. I started at the button pressed [1] and ended up at the walletmodel.cpp [2] which stores your "cached balance" (among other data). Thus I still think my initial hunch is correct. OP is not redownloading, but rescanning the locally available blockchain.

3 clicks (Help -> Debug Window -> Network Traffic) should confirm this.

Ok I found out theymos was partially correct. The link to the wiki was extra helpful. Everything was fixed after I did

Code:

"C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe" -datadir=E:\Bitcoin

I had bitcoin core installed in my HDD while windows are installed on my SSD. Pressing the reset options button made the blockchain redownload but this time in my C drive's appdata.

Maybe resetting the setting also includes reseting the directory. Although at no point was my default directory in C:\Users\YourUserName\Appdata\Roaming\

Bug? I'm not sure. Annoying? Yes.

Thanks for the help.
