Mac OS X operating system can read the hard drive in various ways, and TDM (Target Disk Mode) is one among them. TDM is a boot mode for Mac system that enables it to work like an externally attached FireWire storage media.





The operating system is not loaded on the machine in this system. The FireWire drive can be accessed through the host machine to copy files from and to the concerned volume. However in some cases Mac cannot read the disk and thus data loss problem occurs. This behavior requires Mac data recovery to be resolved.





As a practical example of this issue, you may run across the below error message when you try to mount the Intel-based Macintosh machine in Target Disk Mode-





"You have inserted a disk containing no volumes that Mac OS X can read."


You may encounter this problem when you try to mount the hard drive volumes from an Intel-based Macintosh computer in target disk mode. However, you may see the disk as expected if you try to access the hard drive on a computer having same version of Mac OS X operating system. The error window contains three options - Initialize, Eject, and Ignore. You can opt for either Eject or Ignore.





If you need to format your Intel-based Mac OS X hard drive volume and use it like a boot volume, the host computer must also be an Intel-based Mac computer. However, it is required only if you want to enable Target Disk Mode. Disk Utility can be used to format or repartition the disk volume in such a configuration.
