My Bush-branded T7650 has been faultless for the 2-3 years I have had it but yesterday it wouldn't do anything but show the "need to reformat message". Even the displayed option to reformat later wouldn't work so with trepidation I pressed reformat now option. As expected I lost Library and Timers. The disk had been about 35% full. I started it again and it has since recorded a program with no problem. Interestingly I didn't have to re-scan for channels.

A freak one-off event or is the had disk on the way out?

I might suggest that there's nothing wrong with the hard drive. My own personal experience with this suggests the main board is on it's way out. Been there myself unfortunately. I managed to get a reconditioned box and swapped the hard drives over and watched the recordings. Might be time to think about a new box though....

Cheers. Tom

The need to reformat message has now been replaced with:

"Hard drive initialisation failed. Recording and playback functions are disabled".

As such the box will not record or playback but it will support live TV and features such as Guide are working. I recall seeing some time ago that the answer to a similar problem was to replace the power supply unit and this restored recording and playback.

Any comments/thoughts, please? Should I just bin it?

I'll try that myself later but when we managed to find a replacement box and swapped the hard drive over, using the same power supply, it worked fine. Leading me to think that there was some issue with the main board.

Cheers. Tom

Thanks for trying this. Just out of interest, is the lead on your T7650 threaded through a small rectangular object (5cm x 2cm) with grooves for the wire to pass through? Mine came refurbished and has such an attachment whereas I have seen the exact same psu on a new T7655 but without this extra attachment - puzzled as to what function it has.

The original one (new box when purchased) had the small black box but the other one that I used (from a new 7655 box) didn't. I've also managed to find a reconditioned 7650 box and tried the power block from that, it also has the square black box.

Cheers. Tom

The small black box on the power cable is a ferrite core. It is meant to guard against interference and RF noise, but in my experience it doesn't make a lot of difference.

I concur with Tom. It is likely be a mainboard failure rather than the HDD - the error message comes up because the box has trouble reading the drive (SATA interface issue), and mistakenly issues the error message about formatting. Usually it will fail to format also.
