URGENT ! Will I lose my data

[realmatrix]

I think I may have done the most foolish thing.

I have a 1 TB hdd .It has only 1 partition which is 90% full. Off late I noticed as the the hard disk began to fill up its performance decreased gradually. The culprit seems to be poorly aligned partition as suggested by this post http://www.overclock.net/t/1226963/how-to-properly-re-align-your-ssd-hdd-partitions . So as instructed I ran mini partition tool magic to re align the drive and hit apply . I thought it would hardly take few mins . To my horror its proceeding very slowly.
I realized pretty late that there is hardly any space to move the 850 GB worth of data within the drive itself during the re align process. But partition magic never warned me about low space and proceeded to realign the drive.
I am committed to let the process complete for as long as it takes.

But have a committed the mistake of re-aligning a drive which is almost full and risk losing the data?

It will take quite a while, but DO NOT cancel the process, it is slow, but eventually it will be done. It has to copy all the files on the drive to re-align them, so I wouldn;t be surprised if it took several hours.

It is proceeding at the rate of 5.5 mins / percent . Will take about 9 hours at that rate .Is it copying in blocks of 10-20 GB each time and then deleting and repeating all over again. Since some files are about 20-30 gb each and there is no activity of a cache running on my primary windows partition.

Leave it alone for a day. At this point if its gonna mess something up its too late anyway. Check it tomorrow, it is a very slow process, let it do what it needs to do.

Yup have left it alone. Current transfer rate is about 27 MB/sec . Ideal should be around 40-50 MB/sec . which explains why I did it in the first place.

And always do backup

It completed successfully after 7.5 hrs

It will take some time to complete the process. Don't try to stop the process while it going on. I suggest you to use e-backups like google drive, etc for further uses. It will helps you alot in future.
