In the USA this feature is not in any model. But from what I can tell it's not 100% reliable. So use USB 2.0 drives that are 500MB or less and format them from time to time. Sorry but it's a known support tar pit. Hope you get out of it.
I have this recurring issue with my D6500 TV were timeshift crashes complaining about "read failed"
I blamed and changed my hard drive to get the exact same issue with a brand new one.
Did anybody experience (and fixed) this symptom?
For clarity, the drive passes the speed test.
