I'm afraid that's not possible. all are fragmented at the moment the result would be most likely a bit of what you see in Frankenstein . 
Dear Sir/Madam: We have been configured RAID 5 to one of our Dell PowerEdge R720 server, few days ago one of the hard drives failed and red color light (Warring) was appearing, when I replaced only the failed hard disk drive, the error message "No Boot Device Available" now appears. However, the remaining hard drives are online and look good. I have checked the boot order options, boot sequence option, checked cables inside the server and also installed the failed drive back same as before, still did not solved the problem! How can I get or copy the data inside the remaining hard disk drives? So, then I could go with a clean windows installation. Regards,
Dell PowerEdge R720: "No Boot Device Available".
