Hello,

I have 2 drives that are both 1 TB, NTFS and same allocation unit size. I use GFoodSync to synchronize (mirror) the 2 drives.

But one has 453 GB free and one has 99 GB free!!!! How is it possible!!?
The 2 drives have exavctly the same files on them!

Here is check disk info from drive E:
976759807 KB total disk space.
503536344 KB in 110355 files.
48668 KB in 5016 indexes.
0 KB in bad sectors.
298799 KB in use by the system.
65536 KB occupied by the log file.
472875996 KB available on disk.

4096 bytes in each allocation unit.
244189951 total allocation units on disk.
118218999 allocation units available on disk.


Drive F:
976759807 KB total disk space.
875317876 KB in 143118 files.
68480 KB in 6567 indexes.
0 KB in bad sectors.
310579 KB in use by the system.
65536 KB occupied by the log file.
101062872 KB available on disk.

4096 bytes in each allocation unit.
244189951 total allocation units on disk.
25265718 allocation units available on disk.



How is it possible!?

Thanks,

Perhaps the mirroring process went awry in one of the drives and copied over a portion of the files twice. I've never used GFoodSync though, but it seems plausible. Are you sure that you didn't have anything on the full drive before doing the mirroring, i.e. hidden files and such?

Hey.
I just found the source of problem. Good sync had made hidden folders in both drives and had left back up of some deleted files there. One of the folders had around 300Gb stuff in it!
Thanks anyways,
