After a little reading (thanks for the link), I decided that it was safe to hot-plug my e-sata disk. So, I did. And what happened? A big nothing.<br>
<br>
I've got a WD e-sata disk connected to an Intel ICH7 controller, using the AHCI driver. If I boot with drive powered up, it comes up as device "sda". If I hot-plug it, the device doesn't get created.<br>
<br>
I think I need to kick udev into action, but I don't know the incantation.<br>
<br>
If you're successfully hot-plugging an e-sata disk, can you share some tips.<br>
<br>
Thanks,<br><font color="#888888">
