I have spent over a month download the blockchain for BitCoin in Bitcoin-QT. I am only three weeks from being synced; but, now I am recieving an error and then Bitcoin-QT crashes.

The error states that it is a "Database I/O error". I have restarted it multiple times and it will run for a few minutes before the error reappears and the software crashes again. On one occasion, during startup, the software asked me to rebuild.

I really don't want to start over; as I may have some bitcoins waiting for me and it has already been over a month since I started downloading the blockchain. I have read, that rebuilding may not do any good; and before I begin, I wanted to hear from the experts.


Thank you

Hello; I am new to Bitcoin. I would like to set up a way to have my website visitors to be able to make a donate. I have generated an address in my wallet (I use Bitcoin-QT); and have generated a QR code.

Can I use the same QR code for multiple donation/transactions? My website is very basic HTML (with some javascript)



Thanks for your assistance.

Brian
