Sorry for the lateness, but I can tell you the opposite is true, as I've done just that in the past. You can setup a partition on the N900 that can then be mounted on Win/Linux/Mac. So I can't imagine the opposite would not be true.

Ok... then I'll try later with a pendrive entirely encrypted and see if it's recognized and it's possible to mount it and post here.

Well, after trying the kill alls i can say it is not solving the problem - still not possible to send IM + IM integration is not working.

Confirming what's woody said - it's absolutely possible to open any TrueCrypt encrypted partition/file, no matter is using hostmode, network or whatsnot. Even reading containers written in optical disks is working - well, at least if You actually can enumerate then at all, because current bug in KP is (again...) preventing that (I hope it will get fixed in new release).

Ok... I encrypted a pendrive partition, connected to N900, mounted with H-E-N, but, when I try to mount the partition with TrueCrypt, I get this error:

device-mapper: reload ioctl failed: Invalid argument
Command failed

Anyone knows what it means?

Take a look at the output of the dmesg command (and paste it for us) after that error.

Ok... here you go! I selected the messages which should be related to the problem

What version of power kernel are you running? (if < v48, it's likely the xts problem, which means you didn't read the initial post...). Are you using the newest TrueCrypt version from extras-devel? With what cipher is this volume encrypted?

I've installed this kernel:
http://maemo.org/packages/package_in...settings/0.11/
And I'm using this version of TrueCrypt:
http://216.189.8.164/N900/software/truecrypt/

Useless information. You linked to Linux kernel for power user (settings and overclock) 0.11, and this doesn't tell anything about the used version.
Doesn't exist there anymore. It is in extras-devel now.
