Specs: Win7, 4GB
I managed to make a raid0 but ctrl I does not appear once there is a sata DVD drive attached?
I have LSI_1068e_SAS drivers but non are recognised by the install.
There are lots of 'non compatible' LSI 1068 drivers on the usb stick,IBM,dell and others.
no idea which one to use though?

next step is to try an IDE DVD if I can find one or/and make the usb stick bootable and put my win7 on there and try to install without the sata dvd.

I though once you made a raid from 2 discs then those discs were 'erased'?
one disc of the raid had my installation on it and when I tell the bios there is no raid this installation boots up fine?

Both discs are SSD's.

Any help or pointers or things to try etc etc most welcome as I am lost right now??????

Thanks

First thing I would do is forget about RAID 0, it will achieve nothing, especially with SSD drives. RAID 0 is supposed to speed up disk access by splitting the data between the two disk so half is written to one disk and half to the other. In reality the speed up is minimal unless you are reading and writing extremely large files on a regular basis. Because there is no head seek times on an SSD drive, that problem is eliminated.

The upshot of this is that if one disk should fail there is no chance of recovery.

The fact that you can boot when you tell the BIOS that there is no RAID indicates the then entire operating system is on one drive, not split between the two. Once you have enabled RAID O you need to do a complete re-installation to configure the RAID.

I would leave things as they are and use the second drive for storage.

Cheers StuartS

The problem is/was that the raid disappears once there is a sata DVD installed?
Going to try a different sata DVD drive.
There was also a dodgy cable involved :(

I have HDD sata drives for storage,the ssd's are for the OS.

You missed StuartS's point so pay attention.

With RAID 0 there is no redundancy. No redundancy means should one of the disks in your RAID 0 array fail, you lose ALL data on both disks. Gone, fini, done!

Also, your system is down until you can replace the defunct drive. Then you have to reinstall. Or, if you have a good backup, restore it. In either case, it's still not worth it.

If you have a particular reason for RAID'ing your operating system drive, use a RAID 1 which does provide redundancy. With a RAID 1, if a disk fails, you replace it, the RAID rebuilds and you do not lose any data and there is no down time. Your system stays up and running.

If you're a gamer and some other gamer told you a RAID 0 will make your games run faster, he/she is an idiot and knows nothing about hard drives and RAID arrays. Take it from a computing professional who's been working in the IT field for close to 20 years, and has been an avid gamer since before video games were invented (I started playing pinball at a very young age) a RAID 0 does nothing to improve the performance of games on a computer. The two things that can and will are a good video card and RAM.

My gaming rig has a highend video card and 32 GB's of RAM The reason for all the RAM is, that's where your games run once loaded....not from the hard drive.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
