HWinfo64 blocks Truecrypt to mount a device.

Hi there.

as first sorry for my english. :)

Since few weeks i have the problem that the HWiFO process blocks truecrypt so i cannot mount a HDD. If i kill the process in the task manager (or close the programm) i cann mount a truecrypt encrypted HDD.
Please see below for the error from truecrypt while HFinfo process is running an i try to mount a HDD
and the settings of my HWinfo.
Also in the "Sensor" settings i have disabled monitoring for all HDD

Please let me know what i can do in this case.

Best regards

Hmm, this is an interesting problem. I'm too using TrueCrypt and haven't seen any problems with that.
Are you running HWiNFO in Sensor-only mode ?
Is there some sensor which when disabled will allow to mount the drive ?
Also, attaching the HWiNFO Debug File might shed more light on issue...

Thanks for the additional information.
Which drive are you trying to mount, your primary hard disk primary partition ?
From which drive do you run HWiNFO ?
HWinfo is running with admin rights (installed 4.38-2200) from system windows drive C: and the drive which i try to mount (if HWinfO is already running) is a secondary drive Z: with backups, movies, mp3 and so on...
and also physically it is another drive (C: is a SSD and Z: an normal HDD)

btw: i´m a lazy guy and HWinfo is running at windows autostart and i don´t want to close every time this tool to mount my drive Z: ;-)

oh god YES!!!!!!! finally i can use sensor mode again without having to exit hwinfo to mount a drive , this was a fix that needed to be done ever since the last 6 updates , 4.4 ftw! , thanks

btw maybe you could tell us how exactly youve fixed this , since id like to know how this ever was introduced in the first place since i remember a couple versions back that this bug didnt exist

If you would report this issue earlier, the fix could already be done ;)
The issue was that HWiNFO was holding a handle to a disk for the disk activity sensor during the whole runtime. Even though I opened the disk with sharing enabled, it didn't work somehow with TC. Now I open the disk handle everytime the sensor is reading disk activity data and then close it again.
