So how long does hard drive data recovery take? How much data can be recovered from a drive? How much physical damage did the hard-drive experience? These are all important questions to ask yourself when considering hard drive data recovery. The amount of time it takes to retrieve lost data greatly depends on many different factors. If you are recovering only a handful of important files, the small size of each file probably plays a big role in your recovery time.
The bigger the file, the more time it will take to fully recover. The amount of data that has been deleted or lost is also a major factor in the recovery process. Deleted files never really leave your computer and can only be retrieved using the correct software. When you have deleted a file, there may be no way for the hard drive to track it down and retrieve it.
Data loss due to logical errors during the hard drive data recovery process is also a possibility. Logical errors occur when a file is opened twice in succession. This usually results in data loss, because each time the file is opened, Windows must read it once. This also makes it necessary to determine which read error caused the problem and then correct the problem.
