Sony has discovered a problem in the Cyber-shot® DSC-H2 causing the camera to not recognize SanDisk Memory Stick PRO Duo media cards. This problem does not affect use with Sony® Memory Stick Duo media cards.
Although the problem has been corrected, a small number of affected units have reached consumers. Affected units have serial numbers in the range from 3500001 through 3534250. The majority of the units within this serial number range have already been corrected and include an identifying leaflet.
Sony has created a free firmware update to ensure compatibility with SanDisk Memory Stick PRO Duo media cards. However, to download and install the firmware update, you must use a Sony Memory Stick Duo™ media card. If you are the owner of an affected DSC-H2 camera and have an available Sony Memory Stick Duo media card, download and install the DSC-H2 Firmware Update.
IMPORTANT: Owners of affected DSC-H2 cameras who do not have a Sony Memory Stick Duo media card should contact Sony Support at 1-800-222-7669 (U.S. customers) or 1-866-215-6663 (Canada customers).
