On my dell D630 Laptop i have installed Windows 7 Ultimate. This laptop has got compatible TPM chip. I have enabled everything in bios as well as in OS to get Bitlcoker working.
OS is installed on c: drive. I have other drives as well d: and e:. For C: drive i get enable / disable bitlocker. This drive is shown in control panel - Bitlocker.
But i can't see other drives in control panel for enabling bit locker. When i right click D: or E: i don't get context menu option of " Turn ON BitLocker"
Have a look at the default account policy's here, I have a feeling that there's a lock out policy for drives not formatted in Win 7 (or something like that):
Type gpedit.msc to open the group policy manager. Navigate the tree to Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\BitLocker Drive Encryption\.
Look at both FIXED and Removable drives as I'm not sure how windows differentiates the sata drives.
With the other drives, it's always best to freshly reformat them in windows 7 as NTFS before applying bitlocker encryption. So check this as well.
Let me know if you are successful. Meanwhile I'll try to find a technet article that I read a few months ago with a lot of bitlocker help and post it up for you to read.
