Certainly looks like whatever system SKY+ uses to calculate HS capacity and useage has been corrupted.
At times like this after a simple reboot has failed to correct the error a Full System Reset would be the next step. This of course will wipe the hard drive and reset it to it's native state when would solve the useage issues.
Hi Blagmeister,i had that too,sorry,but the ONLY way is to do a full system reset,as already mentioned.Here is how to do it,just in case you don't already know...Go to Services...then hit 4..0..1..Select
Then select option 7.... FULL SYSTEM RESET..Should take about a minute,and it will shut itself off,but do not worry,usually comes back on in about a minute or so.Hope that helps.
I had to unplug my box anyway to move stuff around and when I plugged it back in the prob seems to have corrected itself, which is nice. Though I'd have to do the housekeeping malarky, and there's neve a good time to do that.
