how do I determine a fix drive on a machine?

[mrpatel]

Hi,
Is there any way to determine if a drive is a fixed drive or a network drive from a batch file or a perl script?


Thanks,

You can do it via API calls. One solution would be to write a simple program in something like C++ and return the result....

The following is a solution for Microsoft operating systems...

#include <iostream>

using std::cout;
using std::endl;

// Get logical drives
DWORD dwLogicalDrives = ::GetLogicalDrives();
if(dwLogicalDrives)
{
  for(int iCnt = 0; iCnt < 32; ++iCnt)
  {
    memset(szDriveRoot, 0, sizeof(szDriveRoot));

    if(dwLogicalDrives & (1 << iCnt))
    {
      // Set drive root
      sprintf(szDriveRoot, "%c:\\", iCnt + 'A');

      // Determine partition type
      UINT uiDriveType = ::GetDriveType(szDriveRoot);

      switch(uiDriveType)
      {
        // Unknown
        case DRIVE_UNKNOWN:
          cout << "Partition " << szDriveRoot << " -> " << "Unknown" << endl;
          break;

        // Root path invalid
        case DRIVE_NO_ROOT_DIR:
          cout << "Partition " << szDriveRoot << " -> " << "Root path invalid"
               << endl;
          break;

        // Removable drive
        case DRIVE_REMOVABLE:
          cout << "Partition " << szDriveRoot << " -> " << "Removable drive"
               << endl;
          break;

        // Fixed drive
        case DRIVE_FIXED:
          cout << "Partition " << szDriveRoot << " -> " << "Fixed drive"
               << endl;
          break;

        // Network drive
        case DRIVE_REMOTE:
          cout << "Partition " << szDriveRoot << " -> " << "Network drive"
               << endl;
          break;

        // CD-ROM
        case DRIVE_CDROM:
          cout << "Partition " << szDriveRoot << " -> " << "CD-ROM"
               << endl;
          break;

        // RAM-Disk
        case DRIVE_RAMDISK:
          cout << "Partition " << szDriveRoot << " -> " << "RAM-Disk"
               << endl;
          break;
      }
    }
  }
}
