Oddity in2TB drive

Airslash
221 100+
Hello,

sorry if this is the incorrect forum, but I have some sort of oddity with my harddrives of 2TB and our software.

I have developed a recorder for recording images from Cameras and dump them on the harddrives. We currently have 4 x 2TB harddrives in the system and the idea is to start on disk 1 till its full and then move to the next one.

I have calculated that each image takes up 64kb, and enforced this by formatting the drive with an allocation unit of 64k so each image fits exactly one cluster.

I have done the following calculation:

disksize / 1024 / 64 / 1.05 to calculate the maximum amount of images that will fit on the drive with a margin of 5% space. This would result in +- 29 million images for a 2TB disk.

However the software started halfway the disk on the next disk, so now my first 2TB disk is halfway full, or so windows says.

Anyone any ideas?
