[Droid Incredible Q&A, Help & Troubleshooting] enigmatl:
This request is meant with respect and NOT as a flame but I have to make this request so others don't follow and potentially change the thread into a debate on whether to resize or not resize the partition.

Please let's not start talking about whether this is a good idea or not nor if doing this can make our phone into a brick. Now that it's been said, those lurking and considering this for themselves can make up their own minds. But there are a lot of things talked about throughout XDA that can make your phone into a brick yet things are done in the name of making our devices better.

And yes. We can take action to reduce the amount of data that apps are taking up. To tell you the truth, I would do that even if I had a 1GB partition. I think always saving space when space can be saved is a good idea.

But just in principle, I and probably others want to reclaim that space on our phones that will never be used by anything. Maybe HTC allocated the space as it's allocated because some users won't use an SD card and will then use that space for their media and other miscellaneous stuff.

But once you have an SD card that's way bigger than the extra space on your phone, it becomes pointless to use that space on your phone for media. So I want it available for data.

So both sides of whether to do this or not have now been posed. I ask can we please get back to the topic of how to though I do thank you for your input.

That said, again, does anybody know how to resize your data partition whether by doing it live with parted or gparted or by editing the data.img file that nandroid via clockwork mod puts out? I would really appreciate it.

I tried making a nandroid backup of the phone through clockworkmod, sending the data.img file to my computer, using toporesize to resize it. And by the way, I was forced to check the resize file only no resize2fs button as not doing this generated an error. I then used md5sum to get an md5sum for the new data.img. I then inserted the md5sum in clockwork/nandroid's nandroid.md5 file (with a linux file compatable text editor). I then sent the entire backup back to the phone in a different clockworkmod/backup folder, used rom manager to restore, selected the new resized backup.

After the flashing was complete, I went into my phone only to find that the data partition still had the same amount free (give or take a few K). I wondered if that's because I had to shrink the system file? I was thinking before I started that it's probable that I would have to shrink another partition that had free space so I chose system. I attempted to repeat the above steps from the beginning this time with the plan of shrinking system.img.

No go. toporesize will not shrink it properly. Errors are reported in the process though when I reload it into toporesize, it looks like it has the size I want. Knowing it would probably fail, I tried to continue anyway. Even with the correct md5sum, nandroid won't even start the recovery of that set. You get a status bar for a second and then, the phone just reboots.

So for now, I'm at a loss but I know this can be done.

Whether using this method or another, does anybody know how to properly change the size of the data partition using WINDOWS?
