I am getting a corrupt file message whenever I try downloading my pictures from my SanDisk Extreme III SD card (that I use with my Nikon D80) using the built-in card reader on my HP 9262 desktop (i do not hook up my camera to the computer. I take out the SD card and insert it into SD card reader directly). Same thing happens with my other sd cards (SanDisk brand as well). Never had this problem with my previous XP-based machine. I checked my cards with my old machine, they work fine. I'm using Windows autostart program (picture viewer) to download, not any other proprietary software.
Basically, the files start transferring with no problem. The computer recognizes the card, even calls out which camera the card belongs to, and file transfer begins. But every so often (about every 15-30 pictures) I get a message saying that file so-and-so is corrupt. I get the option of trying to transfer again, cancel or do not transfer any corrupt files. I hit try again and the file transfers fine with no corruption at all. So the files do end up transferring in the end, but I have to baby-sit the process, which is not acceptable when I am trying to transfer hundreds of images.
Brand new HP 9262 (Intel i5-750, 6 gb RAM) with built-in card reader.
Windows 7 Home Premium
SanDisk SD cards (Extreme III and Ultra II). These are standard SD cards, not SDHC
Nikon D80 and Panasonic Lumix cameras (Extreme III card is formatted for the D80, and the Ultra II card for the Lumix)
Any advice/solutions would be greatly appreciated!
