Don't know if it is an apples to oranges thing but: I have 8 drives on an LSI MegaRaid Controller. In order to set up the config I wanted - I created 4 striped sets of 2 (Raid 0), Then I paired 2 sets into a Raid 1. So I wound up with 2 raid arrays in an equivalent Raid 10 configuration.
When bringing them into windows I created four logical drives on 1 array and 1 logical drive on the second array. Nothing at the windows level lets me see an individual drive. Now with Power Console Plus an raid management tool from LSI I can see the individual drives and the arrays. But this tool is for management of the drives in the array. No other software in my systems sees past the Arrays. The only real difference at the windows level, drive management under Windows shows my array with 1 logical drive as a Dynamic drive with a gold bar above it, the array that is broken up into 4 logical drives is shown as a basic drive just like the single drives normally found in a system. And just in case you are wondering why I configured this way - speed for the primary reason, and I am happy to say that this is a much more robust configuration than my previous Raid 5 config. Also the raid 10 is more redundant - the degree to which depends upon which drives decide to die first. But I have had this config for more than 6 months I am very happy with it. The only drawbacks are cost. In a R5 with 8 drives @160g each you would have roughly 960GB with R10 you wind up with 640GB. But since drives are only about @120 each it's not an absolute Killer. Anyway, it works for me. lol -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Thane Sherrington (S) Sent: Wednesday, April 19, 2006 1:23 PM To: The Hardware List Subject: Re: [H] Ghosting a striped RAID setup At 12:26 PM 19/04/2006, Wayne Johnson wrote: >At 09:35 AM 4/19/2006, Thane Sherrington (S) typed: >>I've got a machine with a screwed up Windows install on a striped >>RAID setup (four disks, ranging from 4.3GB to 80GB.)

Windows shows the RAIDed drives as four separate drives, each the size of the physical drive. Acronis shows them as five separate Promise 1+0 Stripe/RAID 0 - I've never used RAID 0 - is it reasonable to assume that the drives are striped, but that there is a C: drive that has the Windows and programs on it, and then a D, E, and F that have data? If this is the case, and all I want to do is reformat the drive holding Windows and reinstall Windows, then I assume I just have to figure out which of the drives holds Windows and make a backup of that drive (in case there is data on it.) Am I right? T
