This would be a Hard Disk error - this is usually caused by improperly shutting down the console.
I would advise you to back up all your important shows to USB immediately, as HDD errors can cause loss of data.
It is very important to use the Shutdown command from the Heartbeat screen, and not to simply 'turn off' or unplug the console.
This is because the console accesses the hard disk to update operating-system files (among other things) at random intervals, and also requires a short amount of time to 'clean up' after running to ensure a fast and error-free startup the next time.
If the console isn't allowed to do this, then corrupted files can result, especially if power is lost in the middle of updating something!
However, the Check Disk utility (CHKDSK) is provided with the console - this can repair the majority of errors without significant loss of data.
If you can call us on +44 20 8896 1000 I can talk you through the procedure - it usually takes ten to twenty minutes.
In the event of serious hard disk errors, the drive can be wiped clean and/or replaced and the console software re-installed, but this is a drastic measure and will erase all your show files.
