SDMMC_OCR_ADDR_OUT_OF_RANGE Error on L4

I noticed that fatfs when performing single readblock_dma operation occasionally ends up with error 

SDMMC_OCR_ADDR_OUT_OF_RANGE when issuing command:

SDMMC_CmdReadSingleBlock(hsd->Instance, BlockAdd);

Any advice on to why this is happening? In theory this error would trigger if I'm trying to access out of range sector within sd card. But it looks like sector is somewhere at the beginning of the card, far before the end sector. I'm using recent HAL drivers. Could this be a symptom of sd card failure????
