Deleted Files Scan looks through the free space of a volume for files based on your Windows Mac's file patterns. By scanning only the free space it allows the Deleted Files Scan to specifically detect any files that were deleted.

Deleted Files Scan should be used when your drive is working properly but files were deleted by the operating system, another program, or by you via the Trash

The Deleted Files Scan usually takes up to three minutes per gigabyte of free space available on the volume. This makes the Deleted Files Scan faster than a Deep Scan since it is not scanning any known used space on the volume.

Once files are deleted through the Windows operating system, there is no more reference to their original directory structure, file name, or date created/modified. Data Rescue will not be able to detect the original information of that file in the directory structure. Instead, Data Rescue will rebuild any files that it detects based on its file patterns. The results of the Deleted Files Scan will be provided with generic filenames and organized by category in the Reconstructed Files folder.

Deleted Files Scan can utilize FileIQ for finding additional files.

The Deep Scan is a comprehensive data recovery scan that provides the most results possible.

The Deep Scan is a two part scan method. It detects existing directory structures on your PC Mac, and scans the whole hard drive for any file patterns to rebuild the raw data of any recognized files.

The first part of Deep Scan can detect multiple directory structures while scanning the hard drive with more than one volume. This will provide you with results from each found volume, with their original directory structures and file names.

The second part of the Deep Scan searches the entire hard drive for any files based on file patterns. Data Rescue detects over 150 major file types based on the files’ raw data (Deep Scan can utilize FileIQ for finding additional files).

These found files will not have their original directory structure or filenames since Data Rescue is rebuilding the files based on their file design. Instead, these results will be provided with generic filenames and organized by category in the Reconstructed Files folder.

The Deep Scan usually takes up to three minutes per gigabyte. With large capacity hard drives, it may require several hours to complete a scan. Physical issues such as bad blocks on the hard drive may slow down the scan process even longer, but the scan will immediately speed up once it has overcome the bad blocks. Allow adequate time for the scan to finish.

Deep Scan can be used when no volumes or partitions are detected on the drive, when a hard drive is formatted, or when a Quick Scan did not provide expected results. Its comprehensive scanning can return files that the other scan methods cannot.

The purpose of Data Rescue's cloning function is to copy a hard drive or volume to another hard drive or volume, so that the copy may be scanned, reducing the wear-and-tear on the original hard drive. This frees the hard drive from use while preserving the data that was on it for later scanning. Cloning with Data Rescue seeks to transfer all the data from the source to the destination, making a perfect one-to-one copy when possible. In some cases, due to disk errors on the source, copying can be hindered to the point where getting a perfect 100% is not possible because of the huge slowdown in read rate caused by errors; then the goal becomes transferring as much of the source data to the destination as possible within a certain time period.

To use the Clone feature, a spare hard drive is needed with the same or larger capacity than the original hard drive. The Clone feature makes a single pass copy of your hard drive onto another hard drive or into a disk image. Please note the cloned hard drive will be in the same logical state as the original hard drive. This means if the original hard drive is failing to mount or boot, the cloned hard drive will have the same failure to mount or boot. The purpose of the clone is to help overcome any slow reads or possible hardware failures that exist on the original hard drive.

Clone should be used when your drive is presenting hardware problems, such as clicking noises or slow reads and writes. Scanning a drive that may be going bad can potentially decrease its life faster than normal.

Data Rescue has extensive support for RAID drives. If your RAID appears in the source list, you can scan and clone it as a normal drive. However, if the RAID has become misconfigured, or each individual member appears as its own drive, Data Rescue has the ability to create a virtual RAID to simulate the hardware RAID. The following configurations are supported:

• RAID 0 (Stripe)
• RAID 1 (Mirror)
• RAID 5
• JBOD (Concatenated)

Once the virtual RAID is constructed within Data Rescue, it is treated like a regular drive and can be scanned or cloned. Please note that due to the large volume of RAID drives a RAID recovery can take significantly more time than recovering from a single drive.
