My friend has an external sata hard disk, and likes the hot-plug feature.
However, that works only if the appropriate sata setting in the motherboard
bios is set to AHCI (IDE compatibility and RAID are two other options, but
hot-plugging doesn't work with them). The machine has WinXP atm, while Linux
is about to be installed in the following couple of days.
Now, on wikipedia I read that AHCI is supported starting from kernel 2.6.19
and later, while current CentOS 5.2 has 2.6.18. Is it possible to make AHCI
work under 2.6.18 or should I install Fedora instead?
Fedora will become obsolete in a year or so, and I will not be around to
reinstall it again for him, so I would prefer a long-term solution (CentOS).
But I need to be sure that it can be made to do all that fancy
hot-plug-auto-mount-sata-ahci stuff without too much hassle.
Oh, btw, I am talking about hot-plugging using the sata cable --- usb
connection of course already works, but this is a hard disk and speed
increase is highly nontrivial when using sata connection compared to usb.
Any suggestions?
Thanks! :-)
Marko
