On new Ubuntu 10.04 - Windows 7 Dual Boot system, TIH 2010 says new Linux ext4 partition is damaged

Thread needs solution

True Image Home 2010, in the "add a new hard disk" tool, puts a red circle with a white X on the green partition bar which corresponds to a new Ubuntu Linux partition made by the Ubuntu installer which uses the ext4 file system. (I realize ext4 is currently unsupported until TIH2011) The Ubuntu installer supposedly does a good job, and it didn't have to move anything to do it, it only made two partitions out of one empty partition. The hard drive is on a new Dell with no problems so far. The Acronis manual says to go to your system's Computer Manager to do a repair, but Window's Computer Management screen shows "healthy" next to all my partitions. Is this because the ext4 system is not recognized or should I be concerned?

Since TI does not support ext4 yet, the partition will appear as corrupted to TI even though it is not. You can still, however, back up and restore ext4 partitions but since TI doesn't recognize them as a valid and supported file system type they will be backed up in sector-by-sector mode instead of normal mode. All this means is that the partition's image will contain all of the sectors, both used and unused, so the image file will be larger than one made from a partition with a supported file system. In normal mode, TI only saves used sectors in the image file and does not save unused sectors, so the image file is smaller.

Mark:

Thanks so much for the complete reply. It hadn't occurred to me to consider sector by sector backup, though now that you mention it, reading about that once or twice previously comes to mind. I've never done a backup that way before, this will be my first. Should be plenty of space on my external drive for the time being. Looking forward to using the awesome True Image Home software in a new way. Thanks again.

Mike,

download Clonezilla, its free, and works with ext4. I've used it and it works. If you're looking forward to using TIH in SBS mode, you'll be even happier using clonezilla, as the file sizes will be similar to what you get with TIH in its normal file compression mode.
