I am a data recovery engineer and have a clients W700ds with a failed RAID 0 drive. I can get the data back for the client by building the RAID externally with software, but the client has a massive amount of software on the laptop he does not want to lose, so we are trying to get the Laptop to boot. Both drives have been cloned successfully, but on installing the clones I get an 'unknown disk' warning. I presume this is because the drives serial numbers are different to the drives meta data for the original drives.
The system recognizes there is a RAID there because if I try to create a new RAID the error message says there is no room to create a new RAID (the RAID 0 volume was the entire disk size), but does not show the RAID volume as a defined RAID. Is there a way fo force the RAID to either boot or to ignore the 'unknown disks'?

Have you tried deleting the old RAID0 array in the BIOS and then creating a new RAID0 array using new drives in the ThinkPad W700ds, and once that is built doing an image copy of the original/recovered RAID0 array to the new one? It sounds like the old one first has to be removed.

Perhaps pulling the CMOS/RTC backup battery will reset the RAID option to factory default?

From my experience I have never been able to re-boot a cloned RAID 0 from an originally failed RAID 0, although the data is still there.
The next best option may be to manually extract the license files embedded in the registry, or license files scattered over the driver.
Unfortunately, this is one of the risks of using RAID 0.
If this was a RAID 1 it may have been a different story.
