Error 51

I would like to confirm that once you have an error #51 there is no other option but clear and delete everything or 51killer if the box is already modded.



C&DE - all recordings lost but unit will work again



51killer - recordings will work if previously modded





My kids said their Tivo didn't work so trying to solve the problem with a quick 10 minute swap, I took the drive from their S3 OLED tivo and transferred it to another S3 OLED tivo before backing up or looking online to see if there would be a problem. :(



After getting the error 51 on the drive with their shows, replacing it in the original has resulted in the same error 51. I don't recall if I modded either unit although I think both drives were upgraded previously.



What is the easiest way to see if the unit was modded so 51killer can save the recordings?



Can the recordings be saved externally and replaced after the C&DE? (I think I already know the answer but figured I'd ask)



Is there any known way to see the recordings again on the original box if it was not modded?



I don't see any newer similar threads on a search, the last few are several years old now.



Thanks!
