I recently bought two 2TB western digital caviars for bluray rips. I had to buy a pci-e sata controller card as I used up all 6 on my motherboard.

I initially setup a striped volume within windows 7 disk management, all was well until I tried to write to the disk... it would give a write error. I then googled for a solution and someone said to check it for errors and that would solve the issue. It did temporarily, however upon a restart the issue would arise again. It was pretty incosistent, however annoying.

I decided to setup a proper raid 0 on the disks using the controller cards interface at POST. I have just done this no problem, however when back in windows it is only detecting one drive.

I definitely setup the raid array correctly... it's not exactly difficult. The drive can't be faulty as it was working before hand.

I have been getting bluescreens ever since I installed the drives and card... I'm not too sure it's connected however, after diagnosing the problem it looked to be more to do with my soundcard drives, however I'm not ruling anything out at the moment.

Anything I should try, any tips?

 
The size is wrong for RAID1 though. A single 2Tb drive (or 2x2Tb in RAID1) should show as 1862GiB, not 1687.

Start by taking both drives out of the RAID array and checking that, individually, they show the correct sizes. Probably worth running WD's Data Lifeguard against them too.

Exactly... it's very strange, when they are out of the raid array... they display the correct capacity.

I was looking for WD lifeguard yesterday and couldn't find it. I'll have another look just now.

Update Edit*** It passed WD lifeguard.

Well that seems to be it sorted. Thank you very much for all your help especially the last two responses. I had initially used the drivers off the disc I got and they seemed to be fine initially. However after updating I could then fully see the correct capacity.

Then it was just a case of going into disk management and creating a new volume using gpt instead of mbr and all was well.

I hope I don't receive the stupid write error now.

Cheers guys. :D
 
They have exactly the capacity that the manufacturers advertise.

The manufacturers quote capacities in Gigabytes (10^9 bytes) which is a correct SI measurement. Windows on the other hand uses Gibibytes (2^30 bytes) but incorrectly uses GB rather than GiB as the symbol.

To go from Gigabytes to Gibibytes simply multiply by 1000 three times to get bytes then divide by 1024 three times to get Gibibytes.
