Blocks Corrupted in Wallet

[JPoet]

Opened my Bitcoin wallet, got an error message that the chain was corrupt. Tried to fix and each time toward the end it havan I/O error.  When I got to bitcoin.org none of the buttons work to download a new wallet. Any clues why this happened just a few days before everything was ok.

Possibly because your hard drive is failing and files are getting corrupt.
Redownload Bitcoin Core, it works for me. Or do rescan or reindex.

Thanks, any idea how big the block chain is?  I freed up space (had 9 gigs).  Trying again.

And make sure you have at least one wallet.dat backup

I do, made it to five weeks and crashed with I/O error again.  Used the wallet just the day it broke then all of a sudden I relaunched it and I can't sync do to this error.  Well i'll try again, I have my wallet.dat backed up, thanks.

Do you have the private key?

I would suggest using an electrum wallet like Multibit so that you don't need to download the entire blockchain.

Sounds like your hardware is failing. Get a new hard drive and I recommend at least 50G space for the blockchain as there are no truncation options nearing completion in the next 12 months so you will need the space. 50G from a stock standard 2TB drive is not much, heck, a lot of decent games come close to that amount.

Yep. You can get a new SSD just for Bitcoin, or get something like a huge 2TB HDD, which will be more than enough.
As I and Cranky said, your drive is definitely failing, otherwise stuff wouldn't get corrupted randomly.

I am running on a SSD on a surface pro 2 so I cannot replace it.  I think the drive is ok.  Tried to re-load the entire bit core got to 12 weeks before the I/O error showed up.  My luck its all running good till I need it for a payment.  I'll need to try an external drive I guess. I have over 50G free.  Off to buy more stuff

Can I do an external USB drive?

The wallet is encrypted is that what you mean?
Can I safely backup a Multibit wallet ?

My internal is SSD and not replaceable, I'll try external.  Must be a space issue, I hope.

Trying on a big external my only hope.  Thanks

Can I do an external USB drive?

If you have a USB 3 port in your computer then 64 GB or 128 GB USB 3 memory stick should be large and fast enough. In fact it is also possible to install the bitcoin client into same stick: https://bitcointalk.org/index.php?topic=41581.0

I'm referring to your addresses Private keys - You should be able to import them to Multibit, assuming you have them.

You should be able to back it up - I've never personally used Multibit, but I'll look around for you.

So I guess I am confused. I re-downloaded the entire block chain pointing to an external.  It worked fine.  So I bought a dedicated external and re-did it again it was done on seconds. So the external has the wallet and takes no space.  The block chain seems to be under
The ..user/appdata/roaming on the PC. 

So I can't figure out where the issue with the disk is, as now it's fine.  Wallet on external few megs the rest on my PC 23gigs.  And I still have 50 gigs.


Thanks for all your help I seem to be up and running any clues to why or how I would appreciate.  If my SSD is corrupted why is it working maybe a surface pro 2 limitation?

Thanks if you see my next post I am completely confused now.  Running but confused.
