You have a RAID 4 array with four data disks and one parity disk. One of the data disks has failed. While the RAID controller is rebuilding the data on the new disk, a second data disk fails. What is the status of your data now?1.0 Marks Data is recoverable from the remaining disks.Data is intact, no loss.Data on the failed data disk is lost.Data is partially lost.All data is lost.

Solution
The status of your data after a second disk failure in a RAID 4 array would be that the data on the failed data disk is lost. RAID 4 can tolerate one disk failure, but not two. When the second disk fails while the first one is still being rebuilt, the data on the second failed disk would be lost because the parity disk can only recover data from one failed disk at a time.
