Increasing the size of an extended drive
I've got a DX4.2 server with a 450gb extended drive which is almost "full" because we like to keep everything in "cache" for fast access. In other words, we have no purge rules. Since the extended drive is almost full and we don't want to purge anything, I assume the only other option is to increase the size of the extended drive. Is there any documentation that explains how to do that, step by step? One of my coworkers thinks it's as "easy" as installing the new (bigger) drive, shutting down DX, and using Windows Explorer to copy the old drive to the new drive, and then start up DX and "point" it to the new drive. That would be nice if it would work, but I have serious doubts about that, especially after reading this page:

Dx 4.2 is no longer a supported version of Dx.
Your co-worker is incorrect. You cannot just copy the files to a new drive, because the DiskXtender attributes will be removed from the files, and they will no longer be associated to the media.
The only way you will be able to move to a larger Extended Drive in Dx 4.2 will be to remove the current DiskXtender configuration (remove all media from all media folders and run a drive scan. This will remove all file pointers from the Extended Drive).
--Add your new disk to the Dx Server
--Create a new Extended Drive in DiskXtender.
--Create new Media Folders.
--Add all media to new Media Folders and perform the File Restore Task.
--Once the File Restore task is complete, perform the Prefetch task on all media to fetch all files back to the new Extended Drive.
--Verify all functionality.
--Once all functionality is verified, you can delete the old Extended Drive from configuration.
===========
Honestly, I think your best bet would just be to add a 2nd Extended Drive in DiskXtender and begin writing to it, if that's possible. Because of the amount of work needed to perform this task, adding a 2nd Extended Drive might be your best option.
Additionally, I'd recommend that you upgrade DiskXtender to a supported version (Dx 5.50.033 or higher) so that you can take advantage of running on Windows 2000 or 2003, where you have the option of upgrading an NTFS partition from Basic Disk to Dynamic Disk, where'd you be allowed to increase the size of a NTFS partition on the fly.

Yes, we can add another (2nd) extended drive to the system, that will not be a problem.

I think the 2nd Extended Drive is a good choice.
