Sounds like your hard drive has become corrupted,which happens over time with these boxes, which I'm assuming is a YouView box and not the 4k Netgem box.
Have you tried a soft reset? To do this hold the power button on the front for around 10 seconds and the box should restart. Alternatively, you can turn off from the back and power back on.
If this doesn’t work then have you tried a YouView Maintenance Reset (https://community.talktalk.co.uk/t5/Articles/How-to-find-maintenance-mode/ta-p/1429347)?
Try the Factory Reset keep recording option.
You will then need to reset your personal settings (such as parental controls / Set antenna Out to On in Settings: Picture and Sound / Surround Sound etc.) and also reset your scheduled recordings (might be worth taking a note of future recordings before doing this so you don’t miss any).
If all else fails then try a full factory reset from the settings menu. You will lose your recordings but you may be asked to do this before the Support Staff look at other alternatives.
Please note that if you are eligible for a new box, TalkTalk now only supply non-recordable ones or with very limited recording functionality via a usb stick and on one tuner, so it's best to try all alternatives if recording is important to you.
Hope it works but if not then please let us know as you are in the staff's queue for a response.
For a quicker reply can you please ensure you have your personal information up to date in your profile including your TalkTalk landline phone number so your account can be traced. Link here - https://community.talktalk.co.uk/t5/user/myprofilepage/tab/personal-profile:personal-info
If you are unsure of your phone number, you can find this in My Account or dial 17070 from your landline phone and this will confirm the number for you.
