    using HDD Password for FDE with 320-series SSD - what happens with my data?




      thanks for all the information given in the " Intel 320-series SSD and FDE (Full Disk Encryption) questions..." thread - but I'm hanging at some question:


      If  I've installed my OS on a 320 without HDD-Pass all data is encrypted,  ok. Now I want to enable a password. Is it possible to enable the  HDD-Pass in this situation without loosing all data? afaik I'm not able  to CHANGE the HDD-Pass later on, but can i SET it without loosing data?


      If  I want to CHANGE it later on, in my understanding I've to do a full  backup, secure erase the device and set a new pass, am I right?


      I imagine, the same is true if I want to DISABLE the pass?


      What  happens, if I enable the pass and start hanging in a reboot loop as   somenone wrote here? Same answers as the two questions above?


      I  read about the different kind (master, user or so) kinds of passes. In  my Bios there's onle one pass per HDD. Does this have any security  impact?


      How  does the process of secure erasing and deleting the existing HDD-Pass  (I don't mean the aes-keys, I've understood this process) work (aim:  getting a "factory state" ssd without hdd-pass)? Giving the right pass  in the bios, booting from a different drive, doing secure erase with  intel ssd toolbox? What is the thing with disconnecting and connecting  the drive (secure lock?), is this needed? How can I enable/disable the  "secure erase lock" (my words)?


      Very  specfic question: Does anyone now if HDD-pass works fine with a dell  T3500 workstation (Intel ICH10R, possibility to set HDD-Pass in bios  exists for every drive)?


      I'm really happy for any hint!
