![]() ![]() Data Rescue II requires temporary space on a disk or volume other than that from which files are to be recovered. ![]() ![]() From another Mac on which you installed Data Rescue II, with the affected Mac as the target disk in FireWire® Target Disk Mode.Do not install Data Rescue II on the drive, volume, or partition from which you will attempt to recover data as this may result in the overwriting of data you hope to recover.If one uses Secure Empty Trash, the space is overwritten immediately with "ASCII garbage" random ASCII characters or zeros and hence the files are unrecoverable.īefore using Data Rescue II, thoroughly read and understand its documentation.

Your greatest chance of recovering a file intact is to stop using the Mac immediately and try to recover the files with Data Rescue II. It all depends on how this now-free space is distributed on the disk and what write operations you have the operating system perform thereafter. The space may be overwritten immediately, but it may also be days or weeks before it is overwritten. However, the space once occupied by a small file may also be used to save part of a large file. If you delete a small file, the space it occupied may not be overwritten until another file of equal or smaller size is to be written to the disk. When this space will be overwritten depends on a variety of factors, such as how this space is distributed over the drive: large files are frequently distributed over the disk, not written into contiguous space. However, the bits that comprised your data are still there. The space the files occupied is now, from the hard drive's perspective, "free space" "Available" as seen in Get Info that can be overwritten at any time.

If you have implemented our comprehensive backup and recovery solution, the need for data recovery would be minimized. Derived from the "Data Recovery" chapter of our book, Troubleshooting Mac® OS X, this is one FAQ we hope you never have to read.
