Right this has been giving me a massive headache for a while now.
I've just built a brand new system for myself using only one component from my old computer. The backup hard drive which i stored all my program installers and music/pictures etc.
Now i've done this before so i would have thought it would work fine but it won't register in the new system at all... previously the system would only notice the SSD which i've got for the OS but i then had a go at swapping out the SATA cable for the HDD previously mentioned and voila suddenly the 2 HDD's i bought for RAID appeared... but still no backup HDD.
As for my old system... now that i've removed the old HDD it doesn't recognise the 2 HDDs in RAID 0 as a legitimate boot device... neither does it see them when attempting a reinstall of the operating system...
Old system spec:
Asrock extreme3 am2+ mobo
gtx580 twin FrozrII
AMD phenom II 1090t (i think...)
2 x 4gb Ballistix 1866mhz
2 x 700gb HDD in Raid0 (Sata 2)
Sabertooth x79 Mobo
16gb 1600mhz corsair vengeance
OCZ Vertex 4 128gb SSD
2 x WD Red 2tb in Raid0
power supply is a corsair HX1050
Any help would be much appreciated
