I downloaded Bitcoin Core 0.13.1. After starting the program it gives me an error:
2016-11-09 18:38:17 IO error:
C:\Users\PC\AppData\Roaming\Bitcoin\chainstate\304129.ldb: Impossibile eseguire la richiesta a causa di un errore di dispositivo I/O.
2016-11-09 18:38:17 *** System error while flushing: Database I/O error
The error seems to translate to English as "Failed to execute request due to a I/O device error."
You may want to check the state of your disk to make sure there are no issues, also, that your data directory has the correct permissions set.
I hope this helps! :)
Impossibile eseguire la richiesta a causa di un errore di dispositivo I/O.
Apparently means something along the lines of: "The request could not be performed because of an I/O device error."
There is likely an issue with your hard disk. You should create a backup of your wallet.dat, then run disk diagnostics, and perhaps replace the disk in the near future if the diagnostics indicate a problem.
