I have two hard disks. HD1 has two partitions - a NTFS partitions with windows 8.1 and an ext3 with Ubuntu 14.04. HD2 has 4 NTFS partitions. Both of the disks (all partitions) are visible on Ubuntu 14.04. And all NTFS partitions used to be visible/accessible on Windows. But yesterday after upgradeding to Ubuntu 14.04 from 13.10 I am unable to see any HD2 NTFS partitions on windows.
In Device manager panel in windows, on clicking 'scan for H/w changes' it shows the name of my HD2, but partitions still don't show up in File Explorer.
gdisk(orfdiskif the affected disk uses MBR). For Windows to see them, they should have a type code of 0700 ingdisk(or 07 infdiskon MBR disks). If the Windows partitions have some other type code, like 8300 (or 83 infdisk), then you need to change them. – Rod Smith May 18 '14 at 15:18
