I have some old photos on the SD card in my Sony A57. After importing into Lightroom, there are horizontal artifacts on most of the imported photos. This is a screen grab of Lightroom displaying one of the photos.
I have tried this import multiple times with the same result. I shoot in RAW + JPEG. The equivalent JPEG image also doesn't seem to render properly - it just cuts off drawing a certain amount vertically.
The import spans multiple shooting sessions across months, so my guess is that the corruption is occurring in the import process. The photos seem to render fine on the camera display.
I just imported some newer photos yesterday and didn't notice this.
What could be the cause? How should I go about troubleshooting? Is this a bad SD card? Bad data cable?
Should I assume the data on the card is bad (i.e. photos are not recoverable)? Or is this most likely a problem in the import process somewhere?
Should I stop using this SD card at this point?
Update: It is not the mini USB cable that I was using. I cannibalized one from a PS3 controller and the import still had the same symptoms.
