We have 2 raid 5 arrays that need looking at. Array 1 – 4 x 500 gb disk array, one disk failed possibly due to overheat. We cannot get the array to rebuild. I have a new disk for replacement.
Array number 2 – 4 x 500 gb disk, Working OK but 2 drives accidentally removed while machine on. 2 drives still up, 2 drives OK but not online. Drives in both arrays Seagate Momentus 7200.4
What are my options in recovering the files from these raid 5 arrays?, based on us delivering the HDDs and whatever other kit you need, and 2-3 day turnaround? We are a located in Manchester
One of the raid 5 disks is a hard drive was from an external enclosure, has since been removed as I thought it might be the enclosure causing the problem. The hard drive used to show for a couple of seconds on Windows but then became unresponsive and ejected itself. The hard drive does turn on and spins and is detected by windows but will not show up in the disk manager. We consulted raid data recovery company Data Clinic in Manchester (Bury) and discovered that plugging the hard drive directly into my motherboard froze the PC at boot completely. Connecting it to the raid 5 array for data recovery purposes has a similar effect on the raid and we can not access any of the files stored on it.
The raid 5 arrays use the same hard drives – HGST HTS541010A7E630. When we take these hard drives out of the raid array and connect them to a computer some are recognised, others are not.

Can anything be done to recover data?
