Increasing partition without losing data

You can do it with a 3rd party product like Partition Magiic. Windoze (which I'm assuming you are using) doesn't have the capability to do it on it's own.

Quite easy with PartitionMagic. This software allows you to do whatever you want with partitions.

While it certainly is possible, using any of a number of 3rd-Party applcations, to repartition an already-in-use, data-populated drive, given the right application, the deft use of that application, and a bit of luck, its my opinion doing so rarely is a good idea. I happen to think it best to partition a drive as desired prior to installing operating system, programs, and/or other data. I've managed it successfully, and I've had difficulties ranging from perplexing but eventually resolvable annoyances all the way up to spectacular, fix-it-with-format-and-re-install failures.

My general recommendation would be to not attempt it, but if you must, back up everything of any importance to you before beginning.

And have your operating system install disc and product key handy, along with backups of all necessary drivers and the installation media for any peripherals and 3rd-Party programs you use. For 3rd-Party programs, be sure you also have any product key or other validation code that might be necessary as well.

Either way, good luck.

You can partition the additional space as a new drive letter without affecting the current partition. Then use it to store or archive data.

That ain't what he's after, DD - he's looking to conjoin 2 existing partitions into a single full-drive partition. As I said, it can be done, but its nit-picky tricky.

My technique is to obtain another 200GB drive and install it in the system then use PowerQuest or Ghost to copy the original drive to the new drive. During which you can increase the size of the target partition.

I know that means obtaining another drive. But it will absoultly save or protect your old data/system and give you a way to revert if you have a problem.

Also you can partition the 66gb as stated before and create a folder that will show up on the "C:" drive. You can then appear to have just one partition by hiding the D: partition in the explorer.

This will work unless you need storage that is contiguous and assuming you are using XP

I saw that he asked about how to extend his primary partition. I was pointing out that there are easier, safer options that will allow him to use the additional 66 GB of unpartitioned space.
