i have been working with Acronis Partition program, and it seems to work fine EXCEPT... when i am changing the primary boot partition on an NTFS formated Windows 2000 Server Machine (one partition is 60 Gigs - with the OS and Citrix Metaframe XP on it; and the other one has 119 Gigs). i want to increase the size of the first partition (becuase that is where Citrix looks for its files so it is good to have it bigger) - which is actually the M: becuase that is what Citrix makes it during the install... anyway, i go to make this parition larger, and it tells me that it is as large as it can make it. i was going to the 119 and lowering it so there is unallocated space, but it wont allot the 60 to expand over into that new space. One odd thing, is when i was installing the OS and RAID controllers from Dell (poeredge 2600) it limited me to making the first partition 60Gigs. Is this a limit that i cannot go beyond. any help would be greatly appreciated.
