It is easy to replace a failed hard drive in the Youview DTR-T2110 (BT Branded DTR-T2100)
Yesterday morning my BT branded youview box wouldn't get past its loading screen ("Almost Ready..."), and using the maintenance mode to try any reset options resulted in "Failed". Maintenance mode is reached by holding "Down" on the top of the box from Off (red light shown).
This box is 18 months old, and not under any BT contract. BT would replace it if I signed up for a new 12 month contract, but that was not a good deal.
It is straightforward to take out the four screws on the bottom (one under a warranty sticker), and the screw above the SCART connector to lift the top off.
The hard drive is plainly visible, but is screwed in from underneath.
You then need to remove two screws holding the board down, and can then flip it over.
Remove the four screws holding the hard drive in. There is enough space below the lower RF shield/heat plate so that you don't need to remove it to unscrew those four screws enough to remove the hard drive.
Now simply remove the hard drive, and plug in your replacement.
Trying to mount the drive in windows or Linux found only a single 4GB partition, and using the lovely TestDisk software to search for partitions threw up read errors at every sector.
My box had a 500GB hard drive, but I only had a 250GB 2.5" SATA laptop hard drive handy, so that's what I used.
Screws back in, re-assemble, and plug in. I didn't expect it to work without maintenance mode, so I went straight there. I used the "Internet/USB Recovery (Delete Recordings)" option, and about 5 minutes later, the box rebooted, and went to first time setup (Enter post code, scan for channels, update the software, etc).
It has been working fine and recording since yesterday.
-No need to mimic the partition table of the old drive, the box will do it for you. My drive had a single exFAT partition
-I used a smaller drive, not larger, just due to what I had handy. I would imagine a 1TB would work as they sell 1TB models, but larger than that might not work.
-If I hadn't mucked about trying to get the partition table to apply to the new drive, this would have taken 5 minutes total.
