Its not common knowledge that SATA HDDs are capable of being hot-plugged into almost any modern PC. However using them in a plug-n-play manner like portable external USB-HDDs is still not common.
Here is how to use your SATA HDD like an portable HDD.
- Ubuntu 11.10
- DELL Optiplex 380
- Seagate Barracuda 1TB (SATA).
1. Connect the SATA HDD to host PC. (sata-bus + power)
2. Scan for new devices on SCSI host
sudo echo "- - -" > /sys/class/scsi_host/hostN/scanwhere N is the host port number on your host PC to which you have plugged-in the SATA HDD. Usually N=1, assuming the primary HDD on host PC is connected on SATA0.
"- - -" stands for wildcards in place of the
channel number, SCSI target ID, and LUN. More Info
3. Mount the newly detected device locally
sudo mount /dev/sdX /media/temphddwhere X is a/b/c/d etc. Usually X=b, assuming the primary HDD on host PC is enumerated as sda an there are no other block devices.
4. Copy all your data to/from the HDD present at /media/tempHDD.
5. Once finished, unmount the device
sudo umount /media/temphdd
6. Powering down the SATA HDD
sudo echo 1 > /sys/block/sdX/device/deleteEnsure that you refer to the proper device (sdb, sdc etc.) as above in step 3.
