What will happen if I convert my ops disk in a array to dynamic disk?

What do you mean by your ops disk? Your system disk? You can do this, no problem. See the following article: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sag_diskconcepts_10.mspx?mfr=true I quote: "Boot and system partitions. You can convert a basic disk containing the system or boot partitions to a dynamic disk. After the disk is converted, these partitions become simple system or boot volumes (after restarting the computer). " "Mirroring the boot and system volumes. After you convert the disk containing the boot and system partitions to a dynamic disk, you can mirror the boot and system volumes onto another dynamic disk. Then, if the disk containing the boot and system volumes fails, you can start the computer from the disk containing the mirrors of these volumes.

Hi Big Teddy, I want to convert my system disk to a dynamic so that I can create a mirror set. But when I start with the conversion I get the following note : after you covert these disk to dynamic , you will not be able to start other OS. Is it save to convert? Will I loose data? Will my boot partision become corrupted?

I quote, again from the Microsoft literature: "Other operating systems. If you convert a disk with a partition that contains an operating system other than Windows 2000 or , you will not be able to start the computer from that operating system after the conversion. " This is what they are talking about. Yes, it is safe to convert. Make sure your file system is clean first: Run chkdsk, and if it tells you it can't continue, run chkdsk /f. No, you won't lose data (I've done this myself, so I know) No, your computer will boot normally after conversion to dynamic. REMEMBER: You will do this in two steps: 1. Convert your existing boot disk (I assume drive C:) to dynamic. This will make it a simple dynamic volume. (after a reboot) 2. Install a second drive of the same size or bigger, and mirror the existing simple dynamic volume to create a mirrored dynamic volume. (I've done this too, a number of times, so it's definitely ok to do it.) Anyway, the MS lit. says you can, and I've done it many times, so as long as your disk is healthy, DO IT!If you found this post helpful, please give it a "Helpful" vote.

Thanks Teddy, will try it.

Maybe you should have tried it before marking my thing as an answer :-)If you found this post helpful, please give it a "Helpful" vote. If it answered your question, remember to mark it as an "Answer".
