2.2 Drive letters

The meaning of the drive letters depends on the target architectures. However, on most target architectures, drive A is the first floppy drive, drive B is the second floppy drive (if available), drive J is a Jaz drive (if available), and drive Z is a Zip drive (if available). On those systems where the device name is derived from the SCSI id, the Jaz drive is assumed to be at SCSI target 4, and the Zip at SCSI target 5 (factory default settings). On Linux, both drives are assumed to be the second drive on the SCSI bus (/dev/sdb). The default settings can be changes using a configuration file (see Configuration).

The drive letter : (colon) has a special meaning. It is used to access image files which are directly specified on the command line using the -i options.

Example:

 mcopy -i my-image-file.bin ::file1 ::file2 .

This copies file1 and file2 from the image file (my-image-file.bin) to the /tmp directory.

You can also supply an offset within the image file by including @@offset into the file name.

Example:

 mcopy -i my-image-file.bin@@1M ::file1 ::file2 .

This looks for the image at the offset of 1M in the file, rather than at its beginning.
