   I downloaded bitcoin core 0.13.1 after starting the program gives me an error:

   According to the message (translated from italian) this is an I/O error. This likely means there is a problem with the harddisk.

   thanks for your quick answer, what should I do now? do I have to check the hard disk or something else?

   Yes, you could try running some disk checks/diagnostics. If the disk is broken the only safe course of action would be to replace it.

   I run a disk checks/diagnostics. Everything seems ok. But, when bitcoin core start again , after a while it stops. the log debug writes:

   @Bitoma Make a backup of your wallet.dat if you’re worried about your bitcoins - this error refers to LevelDB, which is not the DB used for wallet.dat so probably no need to worry - you should backup your wallet.dat anyway as harddrives don’t last forever.

    ​Good to hear. Make sure to backup your wallet.dat regularly in the future as well. Also, feel free to close this issue if everything is resolved.
