It does sound like a possible hard drive problem.
You could also have a full hard drive, you can check by going to,
Recordings > Recorded > View all > It will say in the top left hand corner on this screen
If it's near to 100% you could try deleting an old recording to see if it makes any difference.
If that doesn't work you could try a factory reset selecting the keep recordings option.
You can either call Virgin on 150 from a Virgin phone, mobile or landline, or 0345 454 1111 from any other phone to report a fault, or wait here for one of the forum team to pick this up which might be 2 to 3 day's.
When phoning choose the option to report a fault, then ignore all the options offered and you should then be placed into a queue to speak to someone.
