Strange DiskSize()

[801119]

Greetings all....
I'm working on a "Whereisit" clone and this is probobly just a blunder of mine, but I can't find the cause!!
when i use this code

 static char * Drive_Letter[]=
 {  // Drive letters
    "A:\\","B:\\","C:\\","D:\\","E:\\","F:\\",
    "G:\\","H:\\","I:\\","J:\\","K:\\","L:\\",
    "M:\\","N:\\","O:\\","P:\\","Q:\\","R:\\",
    "S:\\","T:\\","U:\\","V:\\","W:\\","X:\\",
    "Y:\\","Z:\\"
 };
for( int i = 0 ; i<26 ; i++ )
   {
    int disk_size = 0;
    disk_size = DiskSize(i+1);
   }

(can't remember why I do DiskSize(i+1)
I get the disk_size on my C: to be -11447500080 How can this be? I have a 4gb hdd partitioned to c: -> 3gb and d: -> 1gb, d: though this should not be a problem! D: comes out fine and shows 905 mb! I know this could should work beacuse I've used it before, perhaps made something wrong when I wrote it again... but I just can't find it!! My codes look like something a kid wrote
I have absolutely no idea what I am talking about
Somehow I still manage to make it work

Where are you spitting out disk_size? If it's not in the for loop the variable may no longer point to the correct memory location. The other thing to look at is if disk_size should be unsigned. Just a couple of thoughts at first glance.

Stupid me... I forgot I was working with large numbers, largen then an integer can handle!! The size of the disk is 3150217216 bytes, and I don't know where the limit of an integer is! (never took much care for that, now I see why it's good to know)...

thanks anyway! =D
