jaztool 1.1 ----------- Iomega JAZ/ZIP Tool for Linux Usage: jaztool <dev> <command> where <dev> must be the full name of a scsi device, eg: /dev/sdc, note that you must not specify a partition on the device. <command> can be one of: eject ejects the disk in the drive ro puts the disk into read-only mode, and ejects rw puts the disk into read-write mode, and ejects status prints the read/write status of the disk If the disk is in a password protected mode, you will be prompted for a password when you attempt to change the mode. This version of jaztool does not officially support putting the disk into the password protected read-only mode, but the command 'PWRO' will do this if you are really sure that you want to. REMEMBER: if you forget the password, you will not be able to put the disk back into read-write mode. NOTE: The JAZ/ZIP drives also support a protection mode 5 'PWNR', under which the disk is neither readable nor writable until it is unlocked with a password. This program could not previously unlock a JAZ disk in mode 5 - as Linux 2.x is unable to open a disk that is not readable. To support this feature would require patching the Linux kernel. (And therefore, there is no command to put a disk into this mode, either.) However, as of 2019, and Linux 4.x USB ZIP drives are able to be unlocked from mode 5 using this program. Whenever you change the write-protection mode, jaztool ejects the disk. This is done to ensure that Linux will recheck the mode before it attempts to use the disk again. There is a switch -n if you prefer not to eject the disk after the operation. * (c) 1996 - Bob Willmot bwillmot@cnct.com http://www.cnct.com/~bwillmot/ adapted from work for the Iomega Zip by Grant R.
