I use the "hdparm -b 0" and "hdparm -b 1" commands to facilitate hotswap of IDE hard drives with Fedora Core 1 with the 2.4.22-1.2115.nptl kernel containing Alan Cox's hot swap additions. The code seems to have a bug somewhere, either in the kernel or in hdparm; the disk geometry tables are not getting rewritten by the "hdparm -b 1" command. I can work around it by using the sfdisk command then control-C'ing out of it, but that seems dangerous. Is anyone else using this new feature? Is anyone else seeing the problem? I will submit a bug to bugzilla when I localize this a bit better, but other eyes might help.
