Frequently Asked Questions

Why does my Fios DVR show Error 5101 when I have deleted recordings?
The DVR may need time to update its storage calculations, or there could be hidden system files taking up space. Restart the DVR after deleting recordings and wait 10-15 minutes for the system to recalculate available storage.
How much free space should I keep on my Fios DVR?
Keep at least 10-15% of your DVR storage free to prevent recording errors. This ensures the system has enough buffer space for recording management and prevents Error 5101 from occurring.
Can I upgrade my Fios DVR storage capacity?
Verizon offers different DVR models with varying storage capacities, but you cannot upgrade the hard drive in your existing unit. Contact Verizon about upgrading to a higher-capacity DVR model if you frequently run out of space.
Will I lose all my recordings if Verizon replaces my DVR?
Yes, all recordings stored on the DVR will be lost if the unit is replaced due to hardware failure. Verizon cannot transfer recordings between DVR units, so watch important shows before requesting a replacement.
How do I prevent Fios Error 5101 from happening again?
Regularly delete watched recordings, manage your series recordings to avoid duplicates, and keep at least 10-15% of storage free. Set up automatic deletion of watched episodes if your DVR supports this feature.
