The HOTSWAP utility is reporting that SATA ports not checked as hot swappable are marked hot swappable by Windows 7 64 bit. This utility works OK with three other non-intel motherboards and correctly identifies SATA ports being enabled as hot swappable. Controller mode is AHCI. Bios level 39. The same issued occurred with bios 0061 on the RMA'd DZ77RE-75k motherboard.
It is not a bug, it is feature. According to Intel "Desktop drivers don't include full support for hot swappable, the reason is because it was specifically designed for server board's environment". You can find more details here: /thread/48180 https://communities.intel.com/thread/48180
Although that should work correctly for eSATA ports, as long as you use proper driver. Don't use RST 12.8 it has a bug that does not register devices connected thru eSATA as removable, use either 12.5 or 12.9.
If your BIOS has an option to mark internal ports as "hot pluggable" and you are not going to use RAID configuration you can use default Windows AHCI driver, it worked for me in Windows 8.1, not sure about Windows 8 and 7. With Windows AHCI driver device will be correctly registered as removable if the port is configured as "hot pluggable". Hope this helps.
