Hardware RAID 0 Failed, but both disks are operating, says one of the disks is not a member.

One of my techs tried to transfer data off of a hard drive for a customer that was part of a RAID 0 configuration. Without realizing it was RAID 0 Striped, he took the drive out and connected it to a usb adapter, and plugged it into a windows machine. Windows obviously did not recognize it. When we plug it back into the original machine, the raid fails. It is staiting the the drive that we tried to take the info off of is a Non-RAID disk. All of the data is still on the disk, is there a way to force the RAID program to recognize this disk, and save the info?

I took both RAID hard drives out of the computer with the problem, and connected them to one of our shop computers. I then went to use the raid recovery utility from runtime.org (on the shop CPU), and realized that windows is seeing both raid hard drives combined as one complete hard drive. I then found hope, and thought I would be able to access the combined hard drive through windows explorer, and be able to access the saved info. Unfortunately, when trying to open the hard drive, it tells me that the drive is not Formatted. So it looks like the RAID is somewhat in tact still.

I am working on contacting intel (RAID Manufacturer) and seeing if they offer a utility or suggestion.

Thanks For the help, and let me know if you have any other ideas.

If you break a RAID set it will go offline by default. It is considered broken and the integrity is also breached.

Some RAID controllers allow some flexibility to rebuild a RAID set without initializing it (means wipe) and you might be lucky and get it operational without any major problems. You just connect make a new RAID-0 and say no to initialize. If your RAID controller allows you to do that consider yourself lucky.

Many RAID controllers do not allow you to build a set without a initialize... in that case you have to revert back to your latest backup.

Good luck!

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
