Title: bitcoin-qt failed to read/write block Post by: skyvahaerie on February 16, 2014, 10:29:25 PM As the subject states i have trouble to download the blockchain with bitcoin-qt 0.86 and 0.85 and 0.84 (did not try previous versions, think it won't work either). Always get the failed to read/write block error after a while. I already tried the following:
- started bitcoin with -reindex - reinstalled wallet - deleted block data and directory (did a backup of wallet.dat) - downloaded a bootstrap.dat There is enough free space on my harddrive, i even tried it on a freshly formated disk. System: Win 7 Pro x64 Any help is appreciated. Debuglog: Code: Unable to open file E:\Bitcoin\Bitcoin\blocks\blk00000.dat Title: Re: bitcoin-qt failed to read/write block Post by: rmines on February 16, 2014, 10:32:29 PM Did you check your HDD/SSD's smart status, are there any reallocated bad sectors?
Do you have the same problem on another pc? Title: Re: bitcoin-qt failed to read/write block Post by: cp1 on February 16, 2014, 10:34:06 PM Is your disk full? (when you say there's enough room, is that on C or E, or both?)
Title: Re: bitcoin-qt failed to read/write block Post by: skyvahaerie on February 16, 2014, 10:36:37 PM I have only one pc, so can't check with another. But i have 2 HDD's and one SSD in my rig, i tried it on all of them. I did not check smart status of the disk yet, will do this next. But i don't think all my drives are damaged/dying, quite unlikly. One of the HDD's is not even two days old, bought it last friday.
On all disks are at least 120 GB of free space available. Title: Re: bitcoin-qt failed to read/write block Post by: rmines on February 16, 2014, 10:39:07 PM Are you using Trend Micro Antivirus?
If so try disabling it and downloading the blockchain again https://bitcointalk.org/index.php?topic=171891 Title: Re: bitcoin-qt failed to read/write block Post by: skyvahaerie on February 16, 2014, 10:41:56 PM No, i don't use Trend Micro Antivirus, at the moment i use bitdefender free edition and comodo software firewall. Will try with one/both disabled.
EDIT: Same issue with bitdefender free edition and comodo software firewall disabled, tried it with bitdefender alone and then with comodo alone, same result: Failed to read/write block. Thanks for your input so far. :) Title: Re: bitcoin-qt failed to read/write block Post by: rmines on February 18, 2014, 10:30:27 AM I was wondering if you are still facing the same problem?
If you managed to solve the error, could you post the solution here? Title: Re: bitcoin-qt failed to read/write block Post by: skyvahaerie on February 18, 2014, 01:51:46 PM Did not find a solution. I tested smart status of all my drives and they are good. I have migrated to multibit at the moment, but will keep trying to find a solution, although i have no clue where to look for now.
Title: Re: bitcoin-qt failed to read/write block Post by: Olly_K on February 18, 2014, 02:08:47 PM I had issues with my bitcoin client recently, after upgrading my RAM. After a memtest (google) it turned out I had a faulty module. The client seems to be quite RAM intensive.
Title: Re: bitcoin-qt failed to read/write block Post by: skyvahaerie on February 20, 2014, 03:00:22 PM Tested my Ram now, it works fine too.
I updated my java and i thought that did the trick, as i could download nearly 50% of the blockchain, but then the errors came back. Title: Re: bitcoin-qt failed to read/write block Post by: cp1 on February 20, 2014, 03:10:15 PM Have you tried it just using your C drive, not E?
