Simulate eject of eSATA disk by disabling it?

My system doesn't have support for "hot swapping" eSATA, so there's no
eject or "safely remove" option.

Is disabling an eSATA disk a safe alternative? Will the OS and disk
internal cache be flushed?

Simply perform a normal shutdown in that case. You need mobo support
for hotswap, can't be reliably faked.

By disabling a disk you're perhaps telling the OS not to care?

Well, it's an external disk that I'd like to disconnect and move WITHOUT
shutting down the system.

That's what I was wondering: how much "not caring" is going on? Will it
simply discard what's in the OS cache?

Turn off write caching? Slow things down a bit, but not so much for
archival storage, that way the data is written before the command
completes. Start from the Device Manager -> disk drive -> device
-> policy -> disable write caching.

Good question. A classical umount under any Unix includes a hard
flush to disk before it returns. The question here is how well
MS has copied this. Given the number of mistakes they made when
copying other things, I would not depend it doing a flush.

What you can do is get an eSATA controller that is know to
have hot-swap support with your OS.

Google HotSwap! (with the !). Works for me with an internal hot-plug
SATA caddy.
