Subjectide.c question!

I'm willing to write a little tool for Linux. I noticed, that I can swap Ide
drives on-the-fly, i.e., umount drive, turn off the power of particular
drive, pull of the cable, and it's ok for Linux. The same way I can insert
drive, but.. only the same drive.

So, question: now do I implement a re-probe of devices? So I can insert
drive of new type, and for example:

$ rehashdrives
hda: WDC AC2700F, 696MB w/64kB Cache, LBA, CHS=708/32/63
hdb: OTI-SCYLLA, ATAPI CDROM drive
$

Well, is it possible to call do_probe or any of these procedures in ide.c by
implementing another ioctl? Is it ok for kernel? If so, which exactly
function I should call and how (I know, we'll need to BLKRRPART after
calling reprobe)?


Another question: I have an old buggy maxtor drive - 40 megs. It works, but
not under Linux: "No ??Q after issuing write". What can I do with it? :-)
Maybe, the best interface for this drive is wall, but.. ;-)
