I'm getting this message from the client: "Corrupted block database detected.
Do you want to rebuild the block database now?"

Anyone know what's going on? I don't want to have to re-download the entire blockchain :/

Add

Code:

checklevel=2

To your bitcoin conf file

http://sourceforge.net/mailarchive/message.php?msg_id=31380906

Thanks! However, how exactly do I go about doing that? I'm not a coder.

Shutdown your bitcoin-qt then go to the directory which is based on your operating system...

Code:

Windows %APPDATA%\Bitcoin\ (XP) C:\Documents and Settings\username\Application Data\Bitcoin\bitcoin.conf
(Vista, 7) C:\Users\username\AppData\Roaming\Bitcoin\bitcoin.conf
Linux $HOME/.bitcoin/ /home/username/.bitcoin/bitcoin.conf
Mac OSX $HOME/Library/Application Support/Bitcoin/ /Users/username/Library/Application Support/Bitcoin/bitcoin.conf

Then open or create bitcoin.conf, add the

Code:

checklevel=2

to file save it.

Then start up bitcoin-qt

Do I type that in the terminal or in the finder after first executing 'SHIFT COMMAND G'?

I know that to get into the Bitcoin data files I first execute SHIFT COMMAND G in the finder and then type in ~/Library/Application Support/Bitcoin/
and that takes me to the data files but I don't see andy conf. files.

Then create the file bitcoin.conf and add that line to it.

So I've only just started using Ubuntu very recently. I basically have no idea what I am doing, and I definitely don't know how to install this new version of bitcoin. (Ubuntu software centre apparently still has the older version.)

Anyone care to give me an ELI5? Would be much appreciated.

(I prefer not losing my coins over losing my coins.)

A shame. I can deal with waiting four days to access my coins or move my wallet to an uber fast machine if needed, but not everyone can. If my I5 machine is taking this long, how long would this take on a core 2 duo with 2GB ram?

Hm? reindex shouldn't take longer than an hour or two. What kind of media is this on?

1 TB 5400 rpm laptop hard drive. System is not sluggish otherwise. I am not the only one reporting very long re-index times.

Ok. This prevents it from failing but does not seem to make it go faster. Now at three days running machine non-stop. 15 weeks left to go.

It isn't expected to make it faster. The checklevel refers to only the brief startup sanity check that covers a few hundred blocks.

Would deleting everything and downloading a torrented blockchain be faster or would it still need to re-index?

For the sake of completeness, I should mention that my upgrade on OSX 10.7.5 from the 0.8.3 version to this new 0.8.4 triggered a re-indexation of my blockchain files (OP mentioned only 0.7.2 or earlier).

Same. Unfortunately the re-index has been going on for two days. I have an i5 CPU and 8gb ram, tons of free disk space so I am really surprised it is taking this long. It looks like another day to go.

Anything I can do to make this go faster?

See other threads. re-run with "-checklevel=2"

Gavin or anyone else, still curious about this:

Checkpoint at block 250,000 to speed up initial block downloads
and make the progress indicator when downloading more accurate.

What does this mean? Does it contain or download a truncated version of the blockchain (well, the first 250K blocks) or...?

There seems to be a major bug in the Mac version, it keeps showing and error in the database and makes me re-download the blockchain everytime I try to open the client. I had to revert back to the old version to be able to download the blockchain and access my wallet.

Most likely explanation is one of your blockchain data files is corrupted, but the old version doesn't care. You might be serving up a corrupted blocks to anybody who downloads from you, but you wouldn't notice that either.
