Fatal: extra db err: leveldb/storage: corrupted or incomplete CURRENT file

[actuallymentor]

What I did:

Download geth 1.0.1
Put gets in the chocolatey\geth-stable\tools folder

What happened:

Geth/eth pair mining setup worked fine for a while
Computer crashed (full freeze, no BSOD)
Upon restart trying to run geth any way gives a "Fatal: extra db err: leveldb/storage: corrupted or incomplete CURRENT file"

The contents of the CURRENT files in C:\Users\Mentor\AppData\Roaming\Ethereum* is: "0000 0000 0000 0000 0000 0000 0000 0000"

EDIT: OS Windows 8.1, AMD r9 290, git bash console, previous crashes without repercussions occurred when geth+eth mining.

Your database is corrupted. You can fix this issue by removing the databases and syncing again.

[fjl]

Just delete the blockchain, state and extra folders in your datadir.

Issue solved.

May I suggest adding this to the error? Or make deleting these folders part of the 'geth recover' protocol?

[fjl]

geth recover can recover some errors, but not this kind. We can't really detect this. Genuine corruption like this doesn't happen very often.

Hi,
may you say me where are the blockchain, state and extra folders ? what are the directories ?

The exact location is OS dependent and can be overwritten if you specify a custom datadir. You can see where the default location is with geth -h and check the default value for the datadir flag.

Keep in mind that this datadir directory also contains the keystore for mainnet and testnet. If you want to keep these keys don't delete the keystore sub-directories (each net has its own keystore).

The safest way to delete data and keep keys is to run geth removedb. This asks you what to remove but leaves the keystore intact.

ok
i will be care

@actuallymentor hello, out of interest how you resolved that issue?

[actuallymentor]

@ijunaid8989 please see @fjl's answer.

@actuallymentor Actually, I am not using geth, I am using the only leveldb and my manifest and LDB files are corrupt.
