Followed by

"error: failed to connect best block"

Then "bitcoin-qt has failed".. etc, windows error. After closing I checked debug.log:



2015-07-28 11:16:21 Corruption: block checksum mismatch
2015-07-28 11:16:21 *** System error while flushing: Database corrupted

2015-07-28 11:20:59 Corruption: block checksum mismatch
2015-07-28 11:20:59 *** System error while flushing: Database corrupted

Before this its just all "2015-07-28 11:16:18 UpdateTip: new best=".... type of lines.

What can I do? No way im going to re-download the entire thing again.. HDD is new and in good condition, same for RAM.

Im using 0.10.2 (was too lazy to update to 0.11 to be honest)
