I have install a hard disk on a PC, this hard disk has had a file
system on it , it had been partitionedˇ˘formated under Windows , and
has many files on it. So , I can see the files by printing "@ls "/
ata0a" " in the Shell. Now I want to see the partitions' information
by typing "usrFdiskPartShow" in the Shell, of course, this funtion
need a pointer of "BLK_DEV", But how to get this "BLK_DEV"? There is
no need to implement "ataDevCreate" again, because there had been a
"BLK_DEV", how to find it ?
