Erasing Flash Memory Data
When disposing the computer or transferring the ownership, erase all flash memory drive data in order to avoid data leakage. Even if you erase the data
or initialize the flash memory drive using normal Windows commands, the data can be read with some special software. Use the flash memory drive data
erase function to erase the data completely.
Note that transferring of the ownership without uninstalling the commercial software will be a violation of the software's license agreement.
Erasing Flash Memory Data
The flash memory drive data erase function erases data using an overwriting method, but there is a possibility that due to malfunctions or other oper-
ational errors, data may not be completely erased. There are also specialized devices that may be able to read data that has been erased using this
method. If you need to erase highly confidential data, we recommend that you contact a company that specializes in this process. Panasonic Cor-
poration will bear no responsibility for losses or damages suffered as a result of the use of this function.
