Hey guys so I had the great idea of reorganizing my external drive's partitions with iPartition and it's been stuck at 0% on "Unmounting Disks" for a couple hours now. This is a 2TB drive which originally had three partitions (one for random files, another as a bootable backup and a third as an OS X installer) and now I want just two, where it had to move the partitions around since the two that I wanted combined were on both ends of the drive (hence why I chose iPartition since it should be able to do this type of stuff).

Now, I do have iStats installed and can clearly see that there is disk activity, and there has been since iPartition started doing its thing, and I can also see that it's very uniform (i.e., mostly equal reading and writing), which leads me to believe that it is indeed doing the tedious work of shifting that middle partition over.

I'm going to leave it overnight and see what I wake up to but I wanted to know if any of you have had the same issue with iPartition, or have had any success in shifting partitions around the disk with iPartition. I'd appreciate other people's insight and experience. I'm just worried because the app hasn't updated its progress.

P.S. I think next time it'll just be easier to copy everything to another drive and reformat the first to my liking then copy over everything again. :eek:

Woke up and everything was fine!

So I guess my hunch that there was equal amounts of read and write activity on the disk through iStats proved that it in fact was shifting the partitions around. Everything seems to be in order. Have no idea how long it really took, but I'm sure the fact that it's a USB 3 drive probably allowed for that amount of data to be transferred overnight.

For anybody else who has this problem, if you have iStats and can see that it is indeed reading and writing to the disk equally, [at least for me] just leaving it alone to finish seems to be recommendation. :)

Did you solve this?

Hi!
Same issue here, did you solve this problem?
I am worried about my data.
Thank you!

I am worried about my data.
I hate to state the obvious but did you run a backup before using iPartition? With any disk work or changing the partitions, you need to have a backup.

As for the unmounting issue, are there any other apps open? Closing everything if so and let the application try to do its thing

Done!

Thanks maflynn
It worked! The progress bar never exceeded 0% but suddenly everything went right.
If anyone is in the same situation, I strongly recommend you to wait and be patient. In my case (750 GB almost full), it took about 5 hours to finish…
Cheers!

Its not the fastest process but I'm glad it worked and you don't have any complications.
