- I don't have a technical specification for the Iomega vendor specific SCSI
- commands; all my coding is based on Unix source code. The following values
- can be returned by Zip_Status for disks which have been protected on RISC
- OS. It's possible that newer devices and/or Jaz drives may implement more
- 3-bit protection codes. My Zip drive returns target errors for all codes
- except thos listed below:
-
- Base 10 Binary Meaning
- 0 000 The disk is not protected.
- 2 010 The disk is write protected, no password.
- 3 011 The disk is password write protected.
- 5 101 The disk is password protected for both reading and writing.
