Recovery Success Rate

Data recovery is no black magic. It is rescue attempt based on highly specialized and technological know-how to recover data from damaged media under adverse situation. Inevitably, there are cases whereby data may be unrecoverable. For instance, if the read write head crashes right onto the data platter where serious scratches have been created due to the abrasive force.

Data may also be unrecoverable if it has been totally overwritten and replaced magnetically by a completely new set of data, this is different from common deletion where the deleted data is just marked "deleted" by the operating system and the data contents are still in the data media.

In cases where the data is partially overwritten, a large amount of data may still be recoverable. For instance, if the disk clone "ghost" utility is used with wrong target disk setup, after cloning, data in target disk may be still recoverable as frequently, not all original data is overwritten completely, though complete recovery may not be possible.

There may be other more complex types of hard disk failures which may be unrecoverable. This could be due to lost of critical native firmware original to the hard disk.

One commonly heard about recovery rate exceeding 90% by some recovery vendors. Actually this is never completely true. Recovery rate depends very much on types and models of disks, the failure mode and also types of users’ attempts after disk failure. Some situations could yield recover rate exceeding 95% but others may be just a meager 20% or even less. So, such claims on success rate should be taken as just marketing-hypes.

If ADRC fails to recover your data, no body else could. The capability of ADRC is proven.

Unknown to most, some time the data is still recoverable, if given enough time and resources. However, as data could be time critical and budget is never unlimited, at some point in time it may no longer be feasible to continue such recovery work. The job is therefore treated as unrecoverable, though technically it is still possible to recover the data. For instance, it may take tremendous time to crack a secured file systems with lost passwords or it may take too long to copy a large amount of data from a badly damaged media with deteriorated performance..
