I can't answer your question directly - but from my USB flash card I see that 
hdparm is not reading it as a hard drive.  I can only assume that the CF 
controller chip is not compatible with the hdparm IO for IDE chip drives:

# hdparm /dev/sda

/dev/sda:
 readonly      =  0 (off)
 readahead     = 256 (on)
 geometry      = 1023/32/61, sectors = 1997312, start = 0

# hdparm -i /dev/sda

/dev/sda:
 HDIO_GET_IDENTITY failed: Invalid argument

# hdparm -I /dev/sda

/dev/sda:
 HDIO_DRIVE_CMD(identify) failed: Input/output error
