Status of ESATA in F13 ?

[linux guy]

I am wondering how ESATA devices are supposed to work in F13 these days.

Does F13 support hot plugging of ESATA devices ?
Are they only recognized at boot time ?
Are they supported at all ?

Thanks

I haven't had any problems hot plugging regular sata drives so long as
the hard drive and BIOS support it. Be sure to have your SATA BIOS
settings to AHCI and not IDE. I've done this frequently with failing
drives to minimize their "ON" time so I could rescue as much data as
possible.

No problem at all. One caution - I don't run nautilis, so there may be 
an issue there.

From reading this, it seems that this is dependant upon the hardware 
and which driver gets used.

On my laptop,
I have external drives connected via esata to my pcmcia
esata adapter. I can unmount the drives and unplug them
and re-plug them and re-mount them while system is up.
Ditto with USB drives.
The sata ports on a motherboard are no different.
I am  not so sure about PATA though. I thought those have
to be detected at boot only. Hot swapping PATA (IDE) drives
could lock up or crash your system.

Not always correct.  Internal ports will not be expected to have to deal
with hotplugging, and may not support it.  (You've heard of
manufacturers cutting corners, and not adhering to specifications,
before?)  The host has to support it.

Or electrically damage it.
