I have a Dell Latitude E6440 running Windows 7 x64. It originates from my work and admin installs Trend Micro Full Disk Encryption on all work computers. I was using a Samsung 750GB SSD but it started to fail so I cloned the drive (CloneZilla) to a new 1TB Samsung SSD. All works well except that the encrypted C: partition is still 698GB to fit the old drive.
I tried expanding the partition in Windows Disk Manager (sees the Trend Micro partitions as NTFS), but discovered that this causes a blue screen failure when booted. Makes sense because Trend Micro FDE must have control of the MBR/partition table? This is consistent with 3rd party partition managers seeing the Trend Micro partitions as "unallocated" or "unknown" file systems. Seems the only way to expand the encrypted partition is to uninstall/decrypt FDE then change the partition and re-encrypt - something my work administrators are reluctant to do.
I thought a work around would be to create a new partition from the unallocated space (roughly 230GB - reported as "logical" in 3rd party partition software). Partition is created fine, and a drive letter is applied, and the partition is usable - until I reboot. The partition and drive disappear when rebooted. Checking with 3rd party disk partition programs fails to find the partition when using recovery, so it seems to have been erased, not just lost.
So I'm left with 230GB unusable (well, it's used I suppose as over-provisioning space). Any ideas for how I can make full use of my drive? Or is my only solution to badger my administrators into decrypting (could take days)?
