I have a dual boot system that can either boot up Windows 7, or Ubuntu Linux. I decided to upgrade the hard drives on both Linux and Windows. I put in a 250 GB drive for the Windows side and a 500 GB drive for the Linux side. I already had the drive I replaced (a 400 GB IDE drive) partitioned with half going to Linux and half going to a shared drive between the Linux install and the Windows 7 install. When I copied the partitions, I was left with unused space in both drives. I had the computer booted up in Windows 7 and I decided to combine the unused space on the Linux drive with the partition that had my original “shared” drive. In the control panel I found under Computer Management a subheading of “Disk Management”. I found a command called “Extend Volume” that seemed like just the ticket. I had already tried to install my old copy of Partition Magic and it told me that it had “known compatibility” issues with windows 7. I used the Extend Volume command on the NTFS partition and it appeared to work. Unfortunately, the Linux distribution used something called EXT4 for a partition format. Windows didn’t recognize it, and it destroyed the data on the whole hard disk. Fortunately, I had backed up my important data before I ever started on this mission, and I didn’t lose anything important except more of my life. Let that be a lesson to you. Always back up your data before embarking on a disk resizing expedition.
