Hard Drive Question Dear All, I ordered two matching 4TB drives to use as raid1. I inserted them into a new raid caddy. They did not show up in the windows directories (which I established was down to them not being initialized and no volume yet created). I then found the drives using the disk management button (windows 10). After a couple of dead ends trying to initialize them with both in the caddy I decided to initialize them one at a time. So I took one out and got on with it and it seems to have worked. It shows the correct storage size and I have initialized it and formatted it successfully. I have loaded a test file onto it and all is fine. The second drive when inserted on its own is showing in disk management as as 7451GB (i.e. double what it should). It then gives an I/O device error when I press the initialize button. I have looked up what I/O device error means but these seem to suggest faulty cables or sockets but clearly the raid caddy is fine as one has worked ok. The other solutions were far too complicated to understand and seemed design to solve other I/O problems anyway - not one where the disk shows as double capacity. Any ideas folks ? TIA. T. | |

I'm going to suggest rethinking the use of Raid1. My guess is that you are thinking "It's an auto-backup, how convenient". It's not really though. (It's intended for fault tolerance) So if a backup is your goal it would be better to just periodically copy the files you care about over to the other dive (ideally on another machine). | |

Hi Pinkerton, It is Icy Box IB-RD3620SU3. They have got one the same here: https://www.scan.co.uk/products/2-bay-ic...via-usb-30-esata?v=c It is a model that I have used successfully with other drives for sometime. The HDD is : Western Digital 2TB WD Blue Hard Disk Drive/HDD WD20EZRZ WD Blue, 3.5" HDD, SATA III - 6Gb/s, 5400 RPM, 64MB Cache, OEM of which one has initialize fine. The other, as I say, comes up in disk management at double the proper size. Hi Jade - manually backing up or other system doesn't work for me. it is this or nothing ! T. | |
