| - | ====== Mounting Attached Devices ====== | ||
| - | This page is dedicated to the development of systems to mount attached devices. The hope is that this page will result in a variety of tools which will be able to assist pre and post action scripts. | ||

| - | The script below supports mounting attached USB devices by name volume name. There is support for FireWire devices and non-removable drives commented out. This code should work. The script requires improvements in various areas. Improvements are welcomed [[http://www.lucidsystems.org/contact|via email]]. | ||
| - | \\ \\ | ||
| - | The script below is a work in progress. Even though it works it is certainly not an ideal solution. | ||

| - | # WARNING : This code is quite speggitfied. Assistance with tiding up it would be great. | ||
| - | # | ||
| - | # This is a script to detect attached but unmounted volumes by Volume name and mount them. | ||
| - | # Tested on the following versions of Mac OS X : | ||
| - | # - 10.12.6 intel | ||
| - | # | ||
| - | # | ||
| - | # | ||
| - | # Knowen Issues : - If you rename the disk then somtimes the partition will not be detected. | ||
| - | # If this happens re-partition the disk and try again. | ||
| - | # | ||
| - | # Version 0.3.2 | ||
| - | # | ||
| - | # | ||
| - | # Version History | ||
| - | # 0.3.2 - Added support for USB-Hubs and macOS 10.12.6 - made it a bit messy | ||
| - | # | ||
| - | # Note : Using a (list of) UUID('s) is generally a good approach to mounting devices. | ||
| - | # That is not how this script works. This script mounts volumes via the volume name. | ||
| - | # This approach allows you to add additional devices into a rotation set without | ||
| - | # altering this script or the way you call this script. However, it is extremely | ||
| - | # important to be aware of the potential problems which may arise by using the | ||
| - | # volume name to mount a device before you use this script in any kind | ||
| - | # of production setting. | ||

| - | # Note : it would be better to use xml - | ||

| - | # with the built in RUBy XML system. | ||
| - | # It requires parsing a Mac OS X .plist | ||
