bitcoin-qt failed to read/write block

[skyvahaerie]

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.

Did you check your HDD/SSD's smart status, are there any reallocated bad sectors?
Do you have the same problem on another pc?

[cp1]

Is your disk full?  (when you say there's enough room, is that on C or E, or both?)

[skyvahaerie]

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.

Are you using Trend Micro Antivirus?
If so try disabling it and downloading the blockchain again https://bitcointalk.org/index.php?topic=171891

[skyvahaerie]

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.

I was wondering if you are still facing the same problem?
If you managed to solve the error, could you post the solution here?

[skyvahaerie]

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.

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.

[skyvahaerie]

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.

Have you tried it just using your C drive, not E?
