Hello, I'm needing help about importing tixatis data which contain config, magnets, hashes, etc. to a new HDD not meant to host the OS. Is this even possible? Thanks in advance.

Two methods:
1) copy the %APPDATA% for Tixati under your user account. This would be the .dat files (no transfer downloaded data)
2) Use Settings -> IMPORT/EXPORT and then simply load your .tixaticonfig file

It would also be wise to include your incomplete piece directory.
