partitioning - Ubuntu confuses my partitions

I have 3 relevant partitions split between 2 disks,

• sda2: Windows 1 partition


• sda3: Ubuntu partition


• sdb1: Data partition

I was using pysdm to add a label to my partitions and somehow I seem to have screwed up my installation. Now, every time I access the Data partition mounted in /media/Data I see the files in my Windows partition, and viceversa. I've tried unmounting and remounting correctly to no avail, it seems that wherever I mount sda2, if I access that folder I get the files in sdb1, and viceversa.

Anyone know what may have happened and how to solve this?

Update:

This is the result of blkid:

/dev/sda1: LABEL="System Reserved" UUID="C62603F02603E073" TYPE="ntfs"

/dev/sda2: LABEL="Windows" UUID="00A6D498A6D49010" TYPE="ntfs"

/dev/sda5: UUID="033cac3b-6f77-4f09-a629-495dc866866a" TYPE="ext4"

/dev/sdb1: LABEL="Data" UUID="BCD83AE3D83A9B98" TYPE="ntfs"

These are the contents of my ftsab file:

UUID=033cac3b-6f77-4f09-a629-495dc866866a / ext4 errors=remount-ro,user_xattr 0 1

/dev/sda1 /media/Boot_old ntfs defaults 0 0

/dev/sda2 /media/Windows ntfs defaults 0 0

/dev/sdb1 /media/Data ntfs nls=iso8859-1,ro,users,umask=000 0 0

Use the UUID instead of the device name. /dev/sda and /dev/sdb can change places.

UUID=BCD83AE3D83A9B98 /media/Data ntfs nls=iso8859-1,ro,users,umask=000 0 0
