ESATA suddenly not hot-plugging anymore Tags: Hard Drives Storage Last response: January 3, 2013 12:33 PM in Storage Share tomsuser January 3, 2013 12:10:31 PM Hello, i experience a strange problem: On my new Win7 PC, i have 2 Sharkoon eSATA cases and several Verbatim eSATA drives attached. Normally, i could power them up while runnung the OS and they showed up OK, also the hotplug symbol showed those drives and i could remove them again (mostly ...). But now, neither the disks show up when not directly booted with them, nor does the hotplug symbol appear at all, so that i cannot remove them. I suppose, this happened after i changed some service or auto-start process, but i have no idea which one. Any idea? :-O More about : esata suddenly hot plugging anymore tomsuser January 3, 2013 12:14:51 PM Just to add this: I have "all symbols enabled" for the task-list and also even tested with the symbolic link containing "%windir%\system32\rundll32.exe shell32.dll,Control_RunDLL hotplug.dll", but to no avail. The eSATA drives show only up when booting with them and still, not unplug symbol appears for them. This was different two days agao :-| tomsuser January 3, 2013 12:33:56 PM Now, it seems i found the immediate reason for this behavior: While checking the system, i noticed 8 CPUs shown in taskmanager, so HyperThreading was enabled! I rebooted into the BIOS and noticed that ALL settings were different from what i changed there. HT enabled, Serial and parallel ports enabled - and SATA not on "hotpluggable". As sure i did not do this, *something* managed to change or reset my BIOS settings! :-O Very confusing! It is a Asus P8C WS with the latest BIOS version: 3108 Can't find your answer ? Ask !
