8. IDE Hot-Swapping
12 Mar (3 posts) Archive Link: Ide Hot-swaping?
Pozsar Balazs asked if it were possible to hot-swap IDE drives. Jeremy
Jackson replied, "read a recent man page for hdparm and you will see
kernel allows remove/add ide interface. scripts with correct parameter
usage are in contrib directory of hdparm source. IDE maintainer has code
to electrically turn off (tristate) ide channels on most PC ide chips, but
is waiting to demonstrate at an industry conference before releasing to
public." And Andre Hedrick replied to Pozsar simply, "I have not made
public that code until more clean ups."
This is a part of the man page for hdparm v3.9:
-U Un-register an IDE interface. Dangerous. The com-
panion for the -R option. Intended for use with
hardware made specifically for hot-swapping (very
rare!). Use with knowledge and extreme caution as
this can easily hang or damage your system. The
hdparm source distribution includes a 'contrib'
directory with some user-donated scripts for hot-
swapping on the UltraBay of a ThinkPad 600E. Use
at your own risk.
