Answer» Hard Drive Size Times Cluster Size will give me the Numer of Clusters on that Drive or will it give me how Big the Clusters will be??HD size times cluster size won't give how big the clusters are, because you already would have to know that and use it in the equation, I guess... Wouldn't HD divided by cluster size be amount of clusters?Say you are going to Format another Hard Dive by useing Windows. What I meen is you go into Controle Panle and RIGHT Click on the other Hard Drive you want to Format. You have a Dropdown List for Alocation Size that would be the Size of your Clusters. This is what I don't get what if say you picked something from the list like 512 Bytes and you are going to Format it as FAT 32 and the Hard Drive is say 800 GB Is it not going to OVERRIDE what you just put in fromn the list and make the Clusters the Size they should be??? If so why give us the Dropdown List to pick from???XP won't let you format FAT32 drives larger then a certain size- not sure what it is, I believe it's around 32GB or thereabouts. hard disk size DIVIDED by cluster size will give you the number of clusters. The number of clusters cannot exceed a certain value (32767, I believe). So as long as your number of clusters don't exceed that value, you should be able to use any cluster size. In any case, it doesn't matter- the smallest possible cluster size is the only size that should be used.Quote from: BC_Programmer on October 31, 2008, 06:10:21 PM hard disk size DIVIDED by cluster size will give you the number of clusters. The number of clusters cannot exceed a certain value (32767, I believe). woops, 32768 is FAT-16. replace that with 2^32, or 33,554,432 clusters.Well ok say I have a Hard Drive I added and it is 32 GB in size and I am going to use FAT 32 on it. So I can go into My Computer and Right Click on the new Hard Drive I added and pick Format. And a window comes up telling me it will use FAT 32 and I can pick the File Allocation Size if I want. Now I know Hard Drive Size 32 GB Divided by 16 kB = 2,000,000 Clusters. So this telles me that I will have 2,000,000 Clusters on my Hard Drive by I don't get how this tells me OK you can make EVERY Cluster 512 or OK you can make every Cluster 1 kB and so on. PS......I know I can just pick make Cluster Size as Defalt but I just wanted to know.Quote from: nymph4 on November 02, 2008, 09:00:13 AM Now I know Hard Drive Size 32 GB Divided by 16 kB = 2,000,000 Clusters.

PS......I know I can just pick make Cluster Size as Defalt but I just wanted to know. hard drive size divided by cluster size gives you the number of clusters. if you made a cluster a different size, you wouldn't divide the 32 GB by 16kb, you would divide by the new cluster size. IE, 32KB per cluster would be 1,000,000 clusters.Ok I think I get it now. If I have a Hard Drive that is 32 GB and Divid that by the Cluster Size it will give me how many Clusters I will have on that Drive. I get this it is telling me how many times that Cluster can go into a 32 GB Drive. So if the size of the Cluster changes then the number of how many will be on the Drive. So FAT 32 on a Hard Drive can support a Cluster Size of 16 kB to 32 kB in Size. So as long as I stay within this range I will be ok just the number of how many Clusters I be be able to fit on the Drive will vary RIGHT?It's called arithmetic. DIVISION. Just because we're dealing with computers doesn't mean we flip the whole concept of mathematics on it's head.I think I understand how Cluster size works. If I AD a secondary Hard Drive and it is 8 GB in size I can right click on it and click format. Then just pick Defalt Cluster Size. But if I want to do it by Hand I can just pick from the Cluster Dropdown List 4 kB and it will make every Cluster Size 4 kB in Size. So if I leave this on Defalt Cluster Size will every Cluster Size vary?? Is that the diferance between the two ways??Anyone?
