The -q flag is not supported by busybox, even though it is mentioned
in the usage.
$ busybox hdparm 2>&1 | grep -- '-q\W'
-q Change next setting quietly
$ busybox hdparm -q -c1 /dev/sdb
hdparm: invalid option -- q
/dev/sdb:
setting 32-bit IO_support flag to 1
I tried to write a patch, but it doesn't make much sense. Theres over
200 places where printf() is used throughout miscutils/hdparm.c.
The easier way is to remove the line from the usage, and me
redirecting output to /dev/null...
Patch attached.
