Your disk does not have any NTFS partition. The code-word
Linux under the
System heading indicates one of the standard Linux partitions, ext2, ext3, ext4.
Nor can you use partitions sdb3 and sdb4, which have zero size. Notice that your disk is made of 121600 cylinders, that your sdb1 partition begins at 0 and ends at the 36473th cylinder, while your sdb2 partition begins at 36473 and ends at 121600th cylinder. Thus your disk is completely allocated to these two partitions.
However, what you can do is to use one of the free Windows utilities to access Linux partitions. Windows does not support etx2/3/4 natively, but there are third-party applications that will allow you to use your disk without problems. I know at least three such applications, pick the one that suits you best:
1) DiskInternals Linux reader
Careful, though: these are readers, which means they allow to read data, but not to write to disk. The only one which should be able to write to disk is Ext2fsd, but it does not support journaling, which means that, if you write to it in Windows, and then re-mount in Linux, all sorts of problems might arise. I have never used it to write, I am worried of what it might do to my data, and suggest you may wish to stay away from this feature.
Alternatively, there is Paragon ExtFS for Windows, which is commercial software provided free of charge for personal use. It claims explicitly to be able to write to disk:
Import/Export files and folders from/to Ext partitions. For example, if the hard drive is taken from NAS storage and you need to open a Linux partition and copy from it or place a new file there, Paragon ExtFS for Windows eliminates the need to install the hard drive or configure it for network access. Simply connect a hard drive via the eSATA connector or USB-to-SATA adapter to the PC and access your files.
I have highlighted the relevant parts. I have never used, so I cannot vouch for it.
As for Mac, you can read this enlightening answer from this very same site for solutions.
There is lastly a solution which is viable if Windows, Linux and Mac are running on different machines: attach your disk to the Linux machine, and share the folders. You can read here about a guy who did just that.
sfdisk -l /dev/sdNwhere
/dev/sdNis the actual device name for your portable drive.
blkid /dev/sdb1 /dev/sdb2? If you have any data on the drive you probably should migrate it off. Delete the parition meant for NTFS, and just create the NTFS volume under Windows.
