Intro Hi, I've been trying to get Hot Swap/Plug SATA working for a while now. I have a Gigabyte GA-X58A-UD7 rev 1.0 MOBO, with multiple onboard storage controllers. I have the latest non-beta drivers/BIOS/Firmware of everything. This MOBO contained a bracket which simply converts 2 SATA ports to eSATA ports and directs them + power to the outside of the case. (this is without any chip or so, meaning the Hot Swap/Plug support only depends on if the SATA controller itself supports it) Besides this, I also have a Sharkoon Sharkoon SATA QuickPort Intern 1-Bay Sharkoon said the following about this device: On my MOBO there are the following Storage Controllers: Intel ICH10R (part of the South Bridge) with 6 SATA ports Marvel 9128 with 2 SATA ports Gigabyte SATA 2 with 2 SATA ports JMicron JMB362 with 2 eSATA ports (but no external power) The JMicron is simply disabled in the BIOS (because I want to attach a 3.5inch HDD without casing to it, I also need power) The Marvel 9128 is also disabled in the BIOS. The Gigabyte SATA 2 ports are attached to the 2 ports of the bracket. The Sharkoon QuickPort is attached to the ICH10R. Besides this, there also 2 SSDs attached to the ICH10R (of which 1 contains the OS). AHCI is enabled for all controllers. The OS was installed with AHCI enabled for all controllers (incl the ICH10R). "IDE Native Mode" (an option in the BIOS that exist only for the ICH10R and is also required for allowing Hot Swap/Plug) is only enabled since a short time. The OS was installed with this setting still on "Legacy IDE Mode". (I suspect this might be part of the problem?) In short: all settings in the BIOS are fine I think. I have following problems: The Sharkoon QuickPort on the ICH10R does not support "Safe Removal". This can mean 2 things (which are both wrong): Hot Swap/Plug does not work or Write Caching is disabled The 2 HDDs attached to the bracket (via the Gigabyte SATA 2 Controller) are always in use and can't be safely removed because of this. Below some screenshots: J: and R: are attached to the bracket via the Gigabyte SATA 2 Controller and do show up in the list. G: is in the Sharkoon QuickPort via the ICH10R controller and does not show up in the list. The left window is in the Sharkoon QuickPort via the ICH10R controller and does not have "Removal Options". The right window is attached to the bracket via the Gigabyte SATA 2 Controller and does have "Removal Options". This always happens when I try to safely remove a disk attached to the bracket via the Gigabyte SATA 2 Controller. Even directly after a reboot or even after killing svchost.exe or any other process that has a handle to it, it remains always locked.
