Hmm. You do not confuse two situations, do you? In the past few days I made two devices work. One was a Feiya 5-in-1 CF / SM / SD card reader (Vendor Id: 090c, Product Id: 1132, Revision 1.00). It returned a capacity that is one too large, and becomes very unhappy if one tries to read a sector past the end. So, a flag was needed to tell that the result of READ CAPACITY needs fixing. The other was a Travelmate CF / SM / SD card reader (Vendor Id: 3538, Product Id: 0001, Revision 2.05). It became unhappy when MODE_SENSE asked for too much data. A patch on sd.c solved this. Andries
