Error: "Type 10 Error" in Mac OS


Type 10 Error encountered while using a FireWire or USB drive in a Mac.


According to Apple, this is an attempt to execute an instruction that does not exist in the CPUs repertoire. Basically, the machine on which it is being run does not support the command (for example, a 68020 instruction execution attempt on a 68000).


Apple suggests that you try copying the file to another drive. In addition, you should use disk recovery software, such as Disk First Aid to examine the disk. You can try rebooting with all extensions off as this may allow you to read the data.

More details are available from Apple. Search for Apple Article 55743.
