Default Sector Allocation

[LxMxFxD3]

Hi,

I'm tryin to figure out what to format my raid5 partion in terms of NTFS partition size. I noticed that on my old 300GB drive a 53GB of data (one of my folders) took up "54GB size on disk." But when I transfer this 53GB to a 500GB drive I'm borrowing from my buddy it says "size on disk 63GB". And as far as I can tell I have no idea how to determine what sector size was used for either drive. I am however 100% certain that I used "default" when formatting the 300GB drive.

So, ideally I'd love to duplicate the 300GB sector size on my 900GB raid5 partition, but I have no idea what sector size was used!

Can someone who perhaps knows what size was used for 300GB, please help/post!

Thanks,

Lx

Default cluster size on NTFS partitions is 4096 bytes or 4KB. It is NOT recommended to change this especially smaller. Partitions converted from FAT32 using the CONVERT utility will always have 512 byte ( 1/2 KB!) clusters and these partitions perform poorly and can even cause out of memory errors when defragging, etc.

You CERTAIN that the default is 4096 regardless of whether its 300GB or 500GB? I'm trying to determine why there was such a huge difference in "size on disk" between the two drives.
