OK, so for attaching a drive you'd: 
1. plug-in eSATA cable 
2. power-up drive 
3. hdparm -z /dev/sdx 
4. mount /dev/sdxN /mnt... 

And to remove the drive: 
1. umount /mnt... 
2. hdparm -Y /dev/sdx 
3. power-down drive 
4. disconnect eSATA cable 


The man page for hdparm -Y says that puts the drive in sleep mode. Is 
this more of a precaution, or does it also let the driver know that the 
drive has gone away?
