Hello- I just now sent an e-mail to tech support, but thought that I might try here, too. I have Acronis True Image Home 9.0, Build 3677. I have tried about 6 times so far this morning to increase the size of the secure zone without success. I have increased the size 2 or 3 times in the past without problems. My current secure zone is 11.67 GB, with 1.855 GB free. I have more than enough free space on my C drive (150.6 GB), and I have been attempting to increase the secure zone to 12.99 GB. Being that I do have so much free space, I would like to have about a 3 GB "buffer" for the secure zone. My PC executes all the steps, but after the reboot is complete, when I open Acronis to verify the partition size change, it does not show. It remains at 11.67 GB. I have an HP Pavilion a1220n with Windows XP Home, SP2. Any additional information that may be required will be happily given. Thank you in advance for your time.
