How can I get list of all drives but also get the corresponding drive type (removable,local disk, or cd-rom,dvd-rom… etc)?

Question

How can I get list all drives but also get the corresponding drive type (removable,local disk, or cd-rom,dvd-rom... etc)?

Answer 1

Assuming it's windows, use File.listRoots() to get all roots. Then use FileSystemView to check whether it's floppy disk or a drive. Other than that I have no idea.

Answer 2

The correct way is how Luciano answered with isRemovable property, but I recently had on win 10 that if I started from USB, then USBs were no longer found in that method.

So, I used, for Windows only, the following wmic calls:

ArrayList<File> rootDirs = new ArrayList<File>();
if( isWin )
{


  if( i_dolog )
    LOG.info( "Windows found as OS." );
  ArrayList<String> partids = new ArrayList<String>();

  String results0 = execute( "wmic diskdrive where interfacetype='USB' assoc /assocclass:Win32_DiskDriveToDiskPartition" );
  String lines[] = results0.split( "\r\r\n" );
  for( String line : lines )
  {
    String test = "Win32_DiskPartition.DeviceID=";
    int index = line.indexOf( test );
    if( index >= 0 )
    {
      String partid = line.substring( index + test.length() + 1 );
      partid = partid.substring( 0, partid.indexOf( '"' ) );
      partids.add( partid );
    }
  }
  for( String partition : partids )
  {
    String results2 = execute( "wmic partition where (DeviceID='" + partition + "') assoc /assocclass:Win32_LogicalDiskToPartition" );
    String lines2[] = results2.split( "\r\r\n" );
    for( String line : lines2 )
    {
      String test = "Win32_LogicalDisk.DeviceID=";
      int index = line.indexOf( test );
      if( index >= 0 )
      {
        String partid = line.substring( index + test.length() + 1 );
        partid = partid.substring( 0, partid.indexOf( '"' ) );
        rootDirs.add( new File( partid + "\\" ) );
      }
    }
  }
}

Answer 3

With this code you can get all drives and its type description

File[] paths;
FileSystemView fsv = FileSystemView.getFileSystemView();

// returns pathnames for files and directory
paths = File.listRoots();

// for each pathname in pathname array
for(File path:paths)
{
    // prints file and directory paths
    System.out.println("Drive Name: "+path);
    System.out.println("Description: "+fsv.getSystemTypeDescription(path));
}

Answer 4

File[] roots = File.listRoots();
for(int i=0;i<roots.length;i++)
    System.out.println("Root["+i+"]:" + roots[i]);

Answer 5

This code snippet works on Windows. It correctly reports USB pen drives as removable, but on my laptop a USB hard drive is marked as non removable. Anyway this is the best I found without using native code.

for (Path root : FileSystems.getDefault().getRootDirectories()) {
  FileStore fileStore = Files.getFileStore(root);
  System.out.format("%s\t%s\n", root, fileStore.getAttribute("volume:isRemovable"));
}

Answer 6

There's no definition for what you're asking.

I have a thumb drive which, when I plug it in, shows up as a CD-ROM. After I run a program on the CD-ROM it attaches a second partition which appears to be a hard drive.

I have removable CD-ROM drives. I also have "internal" eSATA hard drives on the outside of my computer.

You'd have to work pretty hard to get a binding definition for the "type" of the drive. Why don't you tell us what you're trying to do, instead of asking about the particular way you want to do it?
