Usually, Deep Scan scans just the empty space of your hard drive for lost data. However, there are cases when a disk is not readable in a usual way, and you can’t even view some non-deleted files (due to partial file system corruption, for instance). Or perhaps you’re unsure which partition your lost data was in, or you suspect one of your partitions is missing.
In this case, it’s important to know that with Disk Drill you can scan the entire disk when needed — both the empty and the occupied spaces. Just select the main disk name (instead of one of its partitions) and click the Recover button. The disk will be treated as having raw file system, and will be analyzed completely. Disk Drill will search for lost partitions and then Deep Scan the entire disk. This means:
- A longer scanning time.
- A much longer list of recovered files to go through (since it includes both deleted and undeleted files).
- The possibility of recovering files from the space which is marked as non-empty.
- Knowing for sure that your lost files will be found, in cases where you weren’t sure which partition your data existed in.
- The possibility of recovering files from partitions that were lost.
Note: It is much quicker to Deep Scan just one partition than an entire drive, so if you know which partition your lost data was in, we recommend you try just scanning that partition first, before you resort to scanning the entire drive.
