Sony has discovered a problem in the Cyber-shot® DSC-H2 which results in the camera's inability to recognize SanDisk® Memory Stick PRO Duo™ media cards. This problem does not affect the camera's use with Sony Memory Stick Duo media cards.
Although the problem has been corrected, a small number of affected units have reached end users. To be an affected unit, the serial number must fall in a 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 upgrade to ensure compatibility with SanDisk Memory Stick PRO Duo media cards. Owners of affected DSC-H2 cameras with Sony Memory Stick Duo media can download the firmware upgrade from:

Note: Owners of affected DSC-H2 cameras who do not own Sony Memory Stick Duo media can contact Sony Support at
