If possible, remove the board from the case and the battery from the board. Dry the board completely using a hair dryer. If the board was exposed to salt water, rinse the board with fresh water and then dry the board. You may try inserting a new battery and downloading the data. If you are unable to access the data, or see any sign of corrosion or tarnishing on the board, contact the place of purchase for a return number. The data may be retrievable, and the logger may be repairable. Charges will apply and are dependent on the amount of damage.

Open HOBOWare, plug the logger back in, then click on Start->Settings->Control Panel->System. Click on Hardware->Device Manager and look for the logger listed under: Other Devices or Human Interface Devices — there could be a minus sign beside one of the categories or a yellow exclamation point through the device. The description listed should indicate if it is a HOBO or not. If it is not a HOBO, do not uninstall it, as it may be another USB device. Delete the "other device," then unplug the logger, wait 15 seconds and plug it back in.

There are two common reasons for data loss:

1. Relaunching a logger before the data has been saved
2. Technical problem with the logger itself.

The following section discusses data loss and its causes; it also discusses methods of retrieving lost data, and how to insure against data-loss problems.
