Yes. I got your point. But can this be made to through few I/O errors and stop instead of resulting in I/O errors for the rest of the data? In the case where data copied is huge, for eg 500MB, the I/O errors are quite lot. > > > It seem not to work very well consistently. > > Vague handwaving comment with no useful information.

Details of few things I noticed is listed below stepwise and to start with card is detected and mounted on mount point /mnt/mmc dir. 1. Start copy of data. 2. Removed the card in the middle of transfer. At the controller driver level this generated card removed interrupt. The mmc_detect_change fn called. 3. I/O Errors generated. 4. Reinsert the card. This generated card inserted interrupt. The mmc_detect_fn called. But the card does not seem to be reinitialized correctly. cat /proc/partitions does not list mmc partitions. The attached log shows that out of 3 trails, it seem to work fine correctly 2 times and failed the third time. So my question is for the above scenario does the MMC/SD core need to take care of anything explicitely or should this be fixed at the controller driver level? Regards, Madhu
