Recover Mac data in case of error - You have inserted a disk containing no volumes that Mac OS X can read

Target Disk Mode or in short TDM is a unique boot mode in Macintosh computers. This boot mode helps you connect your Mac system as a firmware mass storage device and access the data from it. The Mac system booted in Target Mode can be connected through a FireWire port to any Mac or Windows system.

This is extremely useful, in case your Mac system containing all your precious data has failed to boot. However, if you try to boot your Intel based Mac system in Target mode, it fails. Moreover, at times, the Mac volume or drive becomes surprisingly corrupt and becomes completely inaccessible. In such situations, you require any good Mac data recovery software to recover the data back.

You can boot your Mac machine in Target mode by continuously pressing the 'T' key from the keyboard, while starting-up the system. The hard drives connected in TDM can be partitioned or formatted as usual. Users even connect their CD/DVD drives and other such peripherals to the host computers using Target Mode and the resources are easily shared. The problem arises only in case of Intel based Mac systems. Intel based Mac systems, while opened in Target Mode, the operation fails and flashes error message as below:

“You have inserted a disk containing no volumes that Mac OS X can read”

Though, in some versions of Intel Mac, TDM works, still in most of them it fails with the above error message. In such situation, the error dialog box opens with three options – 'Initialize', 'Ignore' and 'Eject'. Here, you must only opt the options, 'Ignore' or 'Eject'.

There are situations, when users do not exactly understand the functionality of an option and perform the operation with curiosity. If by mistake you choose the option, 'Initialize' then the drive will get initialized, leading to the loss of all your data in it.

However, be it the case of your formatted Mac hard drive or any corruption to the drive while booting that in TDM, you can retrieve all your data with the help of any Mac file recovery software. These Mac data recovery software are developed with many innovative techniques to retrieve all your deleted, formatted or inaccessible data back from the Mac hard drive or volume. Moreover, these recovery utilities are completely read-only in nature and with highly interactive graphical user interfaces, quite easy to use.
