Windows 7: 2 HDD = 1 C Drive question

2 HDD = 1 C Drive question

Hi there,

I have an HP Envy 17 that came with 2 1TB HDDs. In windows they appear as a single 2TB C Drive.
How does this work? Is there a way to make them 2 separate drives without reformatting?

It appears the drives are used in a RAID 0 array. Data for each file is stripped across both drives. The drives cannot be separated without losing all data.

That's a good guess, but I would reserve final judgement after we had a look at Disk Management.

Ok so, my problem at the moment is that one drive is giving me warning messages so I was wanting to move all data to the healthy drive and replace the seconadary one... Then maybe looking into RAID1 instead of RAID0... is this not possible?

Yes it says RAID0 in the 'Intel Rapid Storage Technolgy' which is currently giving warnings for one of the drives...

You can only use the array as a whole. I suggest you backup your data to an external drive. Then you can replace the faulty drive and restart at square1.

I would, however, not raid the 2 drives again. If you want OS performance, add a small SSD for the OS. That is a LOT faster than a couple of raided HDDs. Then the user data can go on the HDDs.

The purpose of RAID 0 is to improve performance, which it does. But the rather modest gains under real world conditions are usually not worth the problems it causes. A big one being if one drive fails, you loose everything. And there is more.

I see. In that case - There is a recovery partition which I would need to use in order to restore windows. How do i know which physical disc this is located on, and if it is on the faulty drive what do I do then? Is there a process for backing up the recovery partition?

Is your system still functioning? If yes, it might be easiest to take an image of the OS and reinstall that on a single disk.
