Sony — Non Functional Memory Card

Address:

Dehradun, Uttarakhand

I had purchased a SONY SD-HC 4 GB Memory Card from the Market. My Camera Canon Power A 530 did not recognise Memory Card and error message came " Memory Card Error".
I thought there may be a problem with my Camera or Camera May not be able to support this Memory Card.
I tried to read this Memory Card on my computer through and extension devise ( Card Reader USB Connection"
Here also it stated " error I/O Error.
I submitted Online complaint on the Sony website. After submission of the complaint, I hoped that some one will call up. After waiting for 4 Days, when there was No response, I went to Service Center of SONY on 30.10.2011.
They kept the Card and asked me to come back after 4-5 Days. After 5 days, I again checked up. I was told to come later. I was informed on Phone on 09.11.2011 that I can come and collect.
I went after 45 Minutes of Wait ( Time taken by them to search where the item is lying) I checked the Card on my Camera. Same Memory Card error sign came. The service Center Man inserted that Card in his SONY Camera and It gave remaining memory Picture number. Hoping that it is My camera Compatibility Problem, I came Back. I again Tried to read the card through the Card Reader on my Computer. Again it stated I/O Error. On the same reader my other 256MB Memory Card is reading. I tried to reach Sony Call Center. They stated Again I have to visit SONY Service Center only and they Can not help.
I feel that SONY SDHC Card may be compatible oNLY with SONY Camera's and can not be Used any where else.
I wish to bring this information to the Knowledge of all concerned.
