Each data recovery, file recovery, undelete, RAID recovery, disk recovery or disaster recovery case begins with a free evaluation to determine the potential for recovery and to provide a firm price-quote for your review. Initial diagnosis determines whether the media is accessible to our lab equipment. If so, the first priority is to create a raw image of the data so that logical analysis can determine the nature of the data loss situation. If the media is inaccessible our lab will test the components and closely examine its internal health to determine the extent of physical damage.
Logical recovery uses the raw image by examining the low-level data sectors and determining what fixes to file system structures are needed to get access to the important data. Sometimes the existing file system structures are missing or damaged so much that data has to be extracted directly from one or more fragments of the raw image. Once a recovery has been successfully performed, file lists are created and data validity is checked.
