| - | Note, that when using ddrescue on a partition like this it is important that the destination partition is at least as large as the source partition. Also, the directories for this partition will have all kinds of problems once the process completes (even if it finishes successfully) and you will want to perform a file level copy of all recovered data onto another partition before proceeding further. | + | When using ddrescue on a partition like this it is important that the destination partition is at least as large as the source partition.

| On OS X systems, you should first try another file level restore tool such as Carbon Copy Cloner as it may be that the files located on bad blocks are not important to your recovery attempts. Using Carbon Copy Cloner or even just rsync will typically be faster than using a tool such as ddrescue. However, when needed ddrescue will make every effort to recover files from a drive with bad blocks. | On OS X systems, you should first try another file level restore tool such as Carbon Copy Cloner as it may be that the files located on bad blocks are not important to your recovery attempts.
