Does TrueCrypt support hardware/software RAID and Windows dynamic volumes?
Yes. However, if you use Windows XP/2000/2003, please read the following notes on dynamic volumes (the notes do not apply to Windows Vista and later). If you intend to format a Windows dynamic volume as a TrueCrypt volume, keep in mind that after you create the Windows dynamic volume (using the Windows Disk Management tool), you must restart the operating system in order for the volume to be available/displayed in the ‘Select Device’ dialog window of the TrueCrypt Volume Creation Wizard. Also note that, in the ‘Select Device’ dialog window, a Windows dynamic volume is not displayed as a single device (item). Instead, all volumes that the Windows dynamic volume consists of are displayed and you can select any of them in order to format the entire Windows dynamic volume.
