I have an external eSata disk drive that I want to use on my desktop machine occasionally. I have powered it up and connected it and absolutely nothing seems to happen.
I've done a bit of Google'ing and there doesn't seem to be a very consistent result, I've found everyting from "doesn't work at all" to "works perfectly, just pops up when plugged in". I've searched for it specifically with Ubuntu 10.04 as that's what I'm using.
Has anyone here had success (or otherwise) with hot-plugging eSata disks?
I have had the disk working on another system but I can't remember whether that was hot-plugged or present at power up. I will try rebooting the dekstop with the eSata powered and connected to see if it works then but I really want to be able to hot-plug it.

You're not using an Eee, by any chance?

Not with hot-plugging ones AFAIK, but I have found that with the Eee (or maybe with Xandros, or just Xandros running on an Eee) that sometimes, after removing a device (properly), USB is totally usless until the box is rebooted.

The destructions should tell you if you can.

Yes but we aren't talking about USB mass storage here so your results aren't all that relevant. esata goes in by exactly the same mechanism as the internal disk not USB external ones.

Most if not all SATA chipsets and drives should support hotplug. Whether or not it is supported by the specific SATA chipset on linux is another matter.

Something else that's passed me by then - the onlt external HDDs I've seen plug into USB - and there may be a Firewire version for all I know. So where do you plug it in?

Into (surprise!) an eSata socket, my desktop machine has one on the front, the Acer Revo has one and my wife's Dell Vostro V13 laptop has one, they're becoming 'standard fitment'.
On the Dell Vostro V13 the eSata socket is *also* a USB socket, so there's one dedicated USB socket and a USB/eSata dual-purpose one.

I'll have to get DWP to put the pension up a bit...

Hmmm. Certainly won't be one on the Big Box as I threw that together myself, and I know what's there, within reason - besides, it came at the same time as Win 2000, which I'd guess, predates eSATA somewhat...
AFIK the Acer Aspire 5000 doesn't have one, and I'm sure the Eee doesn't, so I'm unlikely to have met the hole in question.
These pootermolishers keep slipping new gizmos to people behind my back innit.

esata has been working perfectly with hot plug here, a default security policy on the box means that as the disk is considered an "internal" one rather than an external I have to supply the sudo password to mount it. But other than that it just works.

What happens in /var/log/messages when you plug the device in...is it even recognised there ?

Absolutely nothing at all, I can't find *anything* that happens anywhere in /var/log when I plug in the eSata drive. So there's not much chance it's going to be hot-pluggable is there.
It's not a big deal, I can just reboot the system when I plug it in, it's recognised perfectly OK then. I'm aiming to use it as a way of moving very large lumps of data from one system to another (like 100Gb chunks) so having to restart systems occasionally to do it isn't a big problem.
