I have Ubuntu installed on an external drive and Windows installed on my primary "C:" drive. I've been dual-booting this way for years.

Recently, I upgraded my single SSD C: drive (where Windows resides) by adding a second SSD in Raid-0. Now, my existing install of Ubuntu no longer detects my C: drive.

Does Ubuntu not natively detect Raid drives or do I simply need to reinstall Ubuntu?

Must Ubuntu also be on the Raid to detect it?

First: Upgrade. 13.04 is out of support. Upgrade to 14.04 and you won't have to upgrade again until 2019 if you don't want to.

Secondly, you haven't said what sort of RAID this is.

  • FakeRAID (most onboard motherboard RAID controllers) can be detected by dmraid but this needs installing. This is documented and we have older questions about it too.

  • Windows software raid is something else completely. My Google Fu is lacking this morning but everything I find suggests it can't be read from Linux.

  • Real RAID controllers usually work but sometimes need drivers installed. This really depends on the controller.

Usually this is not the case as I have 2 servers and I installed Ubuntu on them, one of them asked during installation if I wanted to activate the RAID drivers, so I'm pretty sure your RAID will be recognized.
