It was a Seagate ST2000VM003 Pipeline HD 2TB 3½” from Amazon at a reasonable GBP60. Fitting was straightforward, simply removing the original and replacing it with this new one, and formatting carried out by the box. Other than the problem described, it has functioned 100% since installation and is only occupied to 25% i.e. about the same quantity of programmes as the original which declared itself 95% full.(500 MB).
I have the same drive, never lost any existing recordings other than deleting them manually or after deliberately filling the disk to check auto delete.
