Changing Hard Drives
Keep the context:
snip The actual drives and the interfaces are of course hardware, but the logics behind splitting data between disks can be handled in both software and hardware. /snip As an MVP you (at least should) very well know that 'interfaces' refers to I/O controllers in the machine, be they plain and simple IDE, SCSI or purpose built controllers. 'Logics' referring to some sort of intelligence that handles the data in the proper manner, given the RAID implementaion used. As an MVP you (at least should) also very well know that, given a couple of regular (dumb) IDE controllers (without any purpose built raid logic incorporated in them) and some plain disks, Windows systems (since the dawn of NT) support fault tolerant RAID implementations. And while were at it, it also supports, non-fault tolerant, but performance oriented RAID implementations. Windows natively can implement this through *SOFTWARE*, i.o.w. a purpose built piece of coding called a driver. The hardware has nothing special to do here, but it's job: accept data presented by the driver and present data requested by the driver. Now, if you are saying: "RAID is a hardware solution.", meaning I've never used it any other way but fork out the extra cash for the hardware unit with the purpose built chip that takes care of all that, then that's an entirely different discussion. purposeful snipping just helps to take things out of context to prove a debatable point. george "Mike Hall (MS-MVP)" wrote in message ...

George
Hardware RAID cards are produced that will work with Win 9x as well as later OS'es.. the hardware variety is undeniably more expensive, but is regarded as generally better, although not in every instance maybe.. software RAID is harder on the cpu.. but you know this already.. My opinion.. hardware raid is the way to go.. reliability has a price, unfortunately.. That said, all this talk of RAID is not helping the OP any.. he is in enough trouble already, having copied, by means unknown, the 'entire' contents of his C drive to DVD in the hope that he can just copy them back.. -- Mike Hall MVP - Windows Shell/user http://dts-l.org/goodpost.htm "george" wrote in message ...

RAID is a hardware solution... I run several system with RAID configs. Apparently RAID is not solely a hardware solution as you can do 'software RAID' in Windows 2003 without the use of a hardware RAID controller. This is news to me, learn something new everyday I guess. Rush http://www.bythedrop.com |

Mike,
Personally I agree with your take on this 100%: Hardware RAID is the way to go, if you need the best in performance, reliability, continuity etc. and can afford the price. I was commenting on your unqualified statement (no disrespect intended): RAID is a hardware solution, that was totally forgoing one of the nice Windows disk storage features for the 'small wallet'. Apparently MS seems to think that too, otherwise they would have dropped that support going from NT4 to W2K when they decided to exchange their own support for it with the Logical Disk Manager from Veritas, that AFAICT probably needed adapting to that feature. :-)) george "Mike Hall (MS-MVP)" wrote in message ...
