USB Drives

We strongly recommend the SanDisk Cruzer USB drives.  These have proven to be, by far, the most efficient and effective USB drives of all that we have tested.  Additionally, they typically cost less than most USB drives!  Below is a list of USB drives that have been tested in the PlotWatcher and proven to perform to the rated specification of 25,000 frames on a single set of alkaline batteries. We recommend that you purchase a 4Gb, an 8Gb or a 16Gb USB drive if you want to insure that you have adequate memory space to last as long as a full set of alkaline batteries. With the extended battery life that you will get with the new firmware, anything less than 8Gb of memory may fill up before the batteries expire. If a USB drive fills up before the batteries expire, it will begin to write over the oldest files on the drive.  (Note: In our User Guide, we state that you can only use a 4 or 8Gb drive.  However, since that Guide was printed, we have improved the firmware in the PlotWatcher and 16Gb Sandisk Cruzers have proven to work effectively in the PlotWatcher.  You may have to format the 16Gb drive before it will work properly, however.  See the information at the bottom of this page explaining how to format a USB drive.)

If your USB drive has been used before, or you are having having trouble with one of the above USB drives, use Windows to format the drive before using it in the PlotWatcher. This can be done by right clicking on the USB drive in “My Computer” and choosing “Format”. Choose the “Fat32 and select the “Quick Format” option.
