I have an Antec tray less caddy connected to the internal ICH8r controller.
AHCI is set in the bios and a fresh install of win 7

When I insert the drive, it gets detected no problem.
When I want to remove the drive, I click on " safely remove hardware and eject the drive. It says its now safe to remove the drive. I remove the drive.
Problem is.... it doesn't detect that the drive has actually been removed.which means that if I insert another drive then that doesn't get detected.
In device manager I have the message
Windows cannot use this hardware device because it has been prepared for "safe removal", but it has not been removed from the computer. (Code 47)

The only way I've found is to "scan for hardware changes" in device manager, it then either detects the drive has been removed or detects the newly inserted one.

The problem is only with the Microsoft Windows 7 AHCI driver and works fine if I install the intel matrix storage drivers, trouble is I need the Win 7 drivers to have TRIM enabled.

Any one have any ideas why its not auto detecting the removal of the drive?

The ICH8R is pretty poor when it comes to dealing with external drives even with AHCI enabled. I gave up trying and got a £10 PCIe Silicon Image based eSATA card instead.

Sorry seems as if Ive missed out some info in my OP. The ICH8r works perfectly with the intel drivers installed.
There must be a reason why the microsoft driver is not detecting removal of the drive.

Shot in the dark here but have you installed the latest chipset drivers? Perhaps even look at a BIOS update..

That's the b**ch about it, I know if I install the intel matrix storage drivers then it'll work correctly.
Thing is I need to keep the Microsoft AHCI driver in order to have TRIM working for my SSD.
