Why Windows needs RAID driver?

From: Nime on 21 Jan 2010 03:04 While in DOS level all drives are visible/accesable why Windows cannot use RAID disks and asks for necessary drivers? Especially during Windows installation. If I format a RAID partition as FAT I may install DOS : ) What's wrong with Win?

The RAID chipset (and the BIOS firmware that supports is) offers one of the four operation modes. 1 - RAID 1a - AHCI (for SATA) - http://en.wikipedia.org/wiki/Ahci 2 - ATA / Native IDE / Legacy IDE / Compatibility 3 - Automatic (RAID/AHCI or ATA?) The first modes 1/1a utilizes the RAID chipset and its performance and security features, but needs windows drivers. The others will work OK without drivers or the above benefits by emulating the command interface of ATA. -- Adrian C
From: Nime on 21 Jan 2010 06:02 I wonder why Windows cannot use generic RAID driver if it's necessary like video card. Then it may update the specific driver. Imagine that a mouse recognized in DOS but not in Windows. Isn't it silly?

It does ask for drivers during installation (Press F6 if you need to install a third party SCSI or RAID driver): http://pcsupport.about.com/od/operatingsystems/ss/installxpnew1_3.htm What's wrong with watching and following directions when you install? :-) I have not - as of yet - had any major issues installing Windows (2000, XP, Vista, 7, 2003, 2008, etc) on various RAID setups. I wouldn't expect (or want) some generic driver that *might* work with somehting as complicated as the Windows operating system anyway - I would prefer (in all cases) to have the latest and best driver the actual manufacturer (*and supporter) of the product in question had. -- Shenan Stanley MS-MVP -- How To Ask Questions The Smart Way http://www.catb.org/~esr/faqs/smart-questions.html |
