I just bought a new HP laptop. It has a built-in SD reader. Every time I put in an SD card, the drive can be found. But when I try to open the drive, OS always says that the SD card is not formatted. I follow that and format the card. But some error messages about I/O errors are shown, and formatting cannot be finished.

I have installed the lastest driver version 2.0.0.6 from HP official site. The problem remains. I also tried the old version, still the same problem.

I am sure the problem is not cards. I have 3 cards, all of them have the same problem as above. When I try them on USB card reader, everything is OK. All of them work in my digital camera, too. Two cards are 128MB from Panasonic, and one is 256MB from Lexar. So the problem should not be because of the size.

Could any1 provide some information about this error? I use windows XP.

Many Thanks

Well, it seems more a bad reader in my opinion. Did you contact HP about it?

HP says it is the problem of drivers. But I have tried almost all versions, none works.
