I do think, that you need a number as you find the following code in hdparm.c
case 'U':
if (!*p && argc && isdigit(**argv))
p = *argv++, --argc;
if(! p) {
fprintf(stderr, "expected hwif_nr\n");
exit(1);
}
sscanf(p++, "%i", &hwif);
unregister_hwif = 1;
break;
isdigit
Returns true if and only if the parameter is a digit in the range 0 through 9.
Or am I wrong??
To the question from greg:
>Why do you care if IDE1 is recognized and registered?
You have already read my thread about “Move kernel to RAM” at
http://lists.debian.org/debian-user/2004/10/msg01086.html
I just need to rescan the IDE-Bus and the only safe way, that really rescans
the bus and works 100% of the time, that appears to me is to make modules
moving them in and out (I hope that insmod “IDE” rescans the bus; some more
research has to be done here). But I also want to experiment with hdparm
(although it might not be what I am looking for).
