The Psion Organiser II
Flash Datapak Formatter Instruction Leaflet

Note that this is the text of the 1990 edition of the instruction leaflet. It does not include information about how to handle Flash packs that contain a different version of the flash driver. This important information can be found in the 1993 edition of the Flashpak Instruction Leaflet.




The Flash Datapak Formatter should be used whenever you wish to re-format a Flash Datapak, erasing all data on it. It is suitable for use with any Psion Organiser II, except model CM. It cannot be used to format conventional Datapaks (which require a Datapak Formatter), or Rampaks.

Before formatting a Flash Datapak you may wish to copy the undeleted data it contains to another pack. Follow the instructions in your Organiser manual to do this.

You may wish to use a mains adaptor while formatting, in order to conserve your Organiser's battery.

Warning! after you have formatted your Flash Datapak, all the information it previously contained will be lost forever.


Turn off the Organiser before inserting or removing packs. To erase a Flash Datapak. both the pack itself and the Flash Datapak Formatter must be fitted in the Organiser at the same time.

When the packs are inserted, turn the Organiser back on. With the main menu displayed, press ON/CLEAR an extra time. The menu item 'Flash' should appear near the end of the main menu. Selecting 'Flash' will offer a new menu from which you may choose to format the Flash Datapak. Select the slot in which you have fitted the Flash Datapak.

You are then given one last opportunity to abandon the formatting procedure. If you continue. the Organiser will indicate the progress of formatting, which may take a few minutes. (Should you wish to interrupt the formatting process, press ON / CLEAR. Your Flash Datapak will then require formatting later.)

When formatting is complete, you may remove the Flash Datapak Formatter, and begin to use your fresh Flash Datapak.

Error messages will be displayed if you attempt to format any pack other than a Flash Datapak, or if you remove the pack too soon. You should in any case never remove or insert a pack whilst the Organiser is switched on.

Note: A freshly formatted Flash Datapak has about 7K of space reserved for the program that enables an Organiser to fully access it. This program is automatically copied onto the pack when it is formatted, and it is thus quite normal for a newly formatted Flash Datapak not to appear completely empty.
