I hibernated my computer (suspend to disk) and added a new SATA disk. After resuming, my Ubuntu 10.10 does not recognize the new disk (while the BIOS did when starting up).

How can I get my machine to recognize the new hard drive without rebooting?

I'm not sure if that's supposed to work. A different approach would be to attach the disk after Ubuntu loaded (SATA should be hot-pluggable, but if it is, depends on your motherboard). –  htorque Jul 8 '11 at 6:58

I found the answer in a blog entry:

$ echo "- - -" > /sys/class/scsi_host/host0/scan

I did that for all 4 channels, and voila - /dev/sdb is there now.
