Author : Creative Team Updated on February 14, 2017

If you find that one of your drive's file system has been changed to RAW, do not run 'CHKDSK' for repair as often recommended. 'CHKDSK' will repair a corrupt partition table in most cases. But if this doesn't happen, you run the risk of losing data on the drive. Stellar Phoenix Partition Recovery 7.0 can be a far more reliable option here. The software allows searching for lost or deleted partitions on your Windows-based drives and helps you recover data from RAW External drives as well 'lost' volumes.
