Where is the article you found indicating that eSATA/SATA is not to be used this way? Of course it's not the boot drive. If eSATA is not supposed to be used for example like USB, why have it in the list of items to be unmounted?
Unlike PATA, both SATA and eSATA are designed to support hot-swapping. However, this feature requires proper support at the host, device (drive), and operating-system level. In general, all SATA/devices (drives) support hot-swapping <http://en.wikipedia.org/wiki/Hot-swapping> (due to the requirements on the device-side), but requisite support is less common on SATA host adapters <http://en.wikipedia.org/wiki/Host_adapter>. That last quote is from: http://en.wikipedia.org/wiki/Esata#External_SATA And while very wrong, I used to hot plug scsi drives all the time on my mac. Thanks for the continued info Brian, just looking to do the right thing with this drive.
