Windows 7: Newby problem - Windows 7 and RAID 5

I'm sorry mate, I didn't mean for you to do a "clean all" (Step One) on the HDDs, I just meant for you to see how to boot to diskpart (Method One) so you could use diskpart to do the partition creation before you started the install.

I like MadTownIdiot's suggestion. Make the drivers signed and install as suggested.

It's typically not recommended to install an operating system to a RAID 5 array. Since it has to calculate parity on each write, you suffer some performance penalties on the drive that the OS is installed to.

Typically, you run a RAID 1 mirror or a RAID 0, 10 stripe for the OS..and then RAID 5 for a data partition.

Yep. RAID 5 for my servers. RAID 1+0 for workstations. I just run RAID 0 b/c I like striping and all data is backed up on server. I'm not quite sure why you'd want to run RAID 5 on workstation unless it truly is mission critical, is hot swappable, and you can't afford it to be down.

BFK - not to worry, the HDD cleaned whilst we were asleep! I then created a 100GB partition as per tutorial, and continued with installing Windows 7 - and got the same result - it refused to install to the partition.

That was using the original driver taken from the Gigabyte DVD. I have downloaded the Intel SATA RAID Driver 9.6.0.1014 suggested by Gigabyte and Lemar. When downloaded, it then self extracts to a file named iata_cd. Clicking on that reveals nothing to my untutored eye that resembles a driver! When I try to load this file as the driver, Windows 7 installer says it cannot find signed drivers.

I am now contemplating usinf Mad Town Idiots suggestion of trying to sign the iata_cd supposed driver. However if someone could have a look at this driver for me and see if it is, or contains a driver, I would be much obliged.

I also note the comments about the in-advisability of loading Windows 7 to a RAID5 drive. Since I only have 4 HDDs, I take it that I need another one (!) if I want RAID0/1 for Windows and RAID5 for data.

A feeling of weariness is descending on my shoulders, and I wonder if I should just load Windows 7 on a single HDD and see if it will talk to a - HDD RAID 5 for data. I've spent a week trying to sort this out, and my wife asked who I was this morning!

I am really grateful to all for their help with this matter.

Hello again Quelle.



Maybe as an experiment you should break the RAID and install to a single HDD to confirm that the machine has no other issues and will in-fact function as intended.

If so just leave a single HDD connected to the mobo for the install; you would have to set the "storage config" in the BIOS back to AHCI, best setting for a single HDD.

A wipe would not be needed but create a single 100GB partition to install to.

Then you would have an install of Windows 7 to "play" with while you research the best RAID config to pursue if that is indeed where you want to go.

Don't enter an activation key when presented with this dialog box during the install, this will give you 120 days to sort how you want to proceed.

shift+f10 will work at anytime before the actual install process starts, but the best time to do it is before clicking "install windows now"
also if you really have to have a redundant RAID setup, and you have (or can get) 4 identical HDDs, why not consider RAID 10?. It will be much faster than raid 5 and just as reliable if you have good hardware to work with, but the problem with RAID is it usually doesn't work very well unless you're using enterprise class HDDs and the motherboard has a good, built in RAID controller. Most of the problems I've seen with RAID have been as a direct result of trying to set it up on hardware that wasn't designed for it, using a PCI RAID controller or worse, software based RAID.
IMO.. the more trouble you have getting windows installed, the more likely it will crash in the future

Dear BFK and all others who have helped me with this

Many thanks for all your help - sorry for the 24+ hour radio silence - car purchase got in the way!

Anyway, in the interim I have had a communication from Gigabyte. They tell me of a new BIOS I should download, and a different RAID driver download. They also tell me that a bootable RAID with an O/S on it is limited to 2 TB - so I was snookered from the outset!

Also in the interim I have unconfigured the RAID 5 and loaded Windows 7 successfully on a 100GB partition on one of the four 1TB HDDs.

Enter my son, visiting from the south of England last evening, who took over the whole shaboodle, and has now given me four separate named drives and downloaded stuff I didn't know I wanted....!

So I am not quite where I wanted to be with my new PC build, but having something constructed and having learnt a lot and increased my confidence has been very good. A really good experience has been the tremendous help you guys have given me - for which I am deeply indebted.

Now I go into a state of deep meditation and work out what to do next...RAID 10? Who knows!
