当u盘里的剩余空间超过一半时，jconfig就无法获取到它的信息？
程序如下：
package com.xu.ycoe.commons.util;
import java.io.file;
import com.jconfig.diskvolume;
import com.jconfig.fileregistry;
public class disk {
private string name;
private string id;
private long volume;
private long freevolume;
private int type;
public disk（) {
file curdir = new file（ "c:/ ");
fileregistry.initialize（curdir, 0);
diskvolume[] diskvolume = com.jconfig.fileregistry.getvolumes（);
for （int i = 0, c = diskvolume.length; i < c; ++i) {
diskvolume diskvolume = diskvolume[i];
string rootname = diskvolume.getprefix（);
this.setfreevolume（diskvolume.getfreespace（));
this.setid（diskvolume.getreferencenumber（) + " ");
this.setname（diskvolume.getdisplayname（));
this.settype（diskvolume.getflags（));
this.setvolume（diskvolume.getmaxcapacity（));
system.out.println（ "======== " + name);
system.out.println（freevolume+ "freevolume: ");
system.out.println（volume+ "volume: ");
system.out.println（ "type: " + type);
system.out.println（ "id: " + id);
}
}
public long getfreevolume（) {
return freevolume;
}
public void setfreevolume（long freevolume) {
this.freevolume = freevolume;
}
public string getid（) {
return id;
}
public void setid（string id) {
this.id = id;
}
public string getname（) {
return name;
}
public void setname（string name) {
this.name = name;
}
public int gettype（) {
return type;
}
public void settype（int type) {
this.type = type;
}
public long getvolume（) {
return volume;
}
public void setvolume（long volume) {
this.volume = volume;
}
/**
* @param args
*/
public static void main（string[] args) {
// todo auto-generated method stub
new disk（);
}
}
在控制台打印出来的结果：

而我还有一个u盘（为空），为m:则无法获取到，而当我将u盘装上东西（超过容量的一半），打印出的信息如下：
