How to check if a drive is valid

Hi.
 
I am trying to find a way to check whether a drive is valid on the hard disk. Ex: if I name a network drive to T: is there an API I can use to check that T: is valid (maybe the network is down?).
 
I would appreciate any hint or help on this.
 
Thanks.

hi
I don't know the api but you can do this with CFile.
save an empty file to the drive, if it success it will returns 1 else it returns 0
 
CFile f;
if(f.Open(drive_path+_T("\\\\a.txt"),CFile::modeCreate|CFile::modewrite)){
   f.Close();
   //drive_path is valid drive
}else{
   //drive_path isnot valid
}
