How to clone exist RAID to an upgarded RAID?

February 8, 2011 at 04:24:24
Specs: Windows 7 x64 Pro, core2duo-3ghz / 8gb
I have installed a new 2x 1TB RAID zero partition. I used EASEUS Partition Master H.E. to copy the existing 2x 512GB RAID C:\ partition to D:\ RAIDzero2T. I set the partition to active in the control panel after copying. I set up new boot parameters using EasyBCD. I changed the BIOS to boot from D:\ RAID channel 1 instead of channel 0 = C:\ . Windows won't boot. Can I make the copy a bootable partition. Part Master would not copy until I turned off boot partition by un-allocating the new RAID. I tried 2 other drive clone programs also. Acronis would not recognize the Western Digital drives in the nVidia RAID. Then I tried Clonezilla, It took 9 hours and it only copied one physical disk of the RAID, useless waste of time.

I think you didn't copy the boot loader. Might be able to use repair tools by booting to W7 DVD.

JoeMomma where to begin:

"1TB RAID zero partition"

Raid0 has no fault tolerance and you only put data there you don't care about. If you are storing data that is important to you Raid1 is the bare minimum.

"I set the partition to active in the control panel after copying."

A correctly done clone already has the partition set to active. A disk clone captures not just files but those things that are not files like the mbr and boot info

"I set up new boot parameters using EasyBCD."

Again not needed

" it only copied one physical disk of the RAID"
That would be correct. You would never clone each disk separately.

When you look at this disk array in Windows Disk Management do you see two drives? No, you only see one. You would never clone each disk. This is because you need the raid controller doing this.

Think of it this way. You have 4 oil drums each representing a drive. You have a dual oil loader which means you can pump oil into two drums at a time. This oil loader is your raid controller. You have a big tank full of oil you need deposited in the oil drums.

Do you take the oil direct from the tank to the drums? No because they would not fill correctly. Remember now, if you break that raid0 set you have LOST ALL DATA WITH LITTLE HOPE OF RECOVERY.

The point being is you have to clone while both raid arrays are active and you will see this only as one drive being cloned to another.

After that take the power away from the drives in the old array and set the new one as the boot in the raid controller and you should be fine.

Answers are only as good as the information you provide.
