Bare Metal Restore - No Partition Table
Posted on 2013-02-01
I would like to get your thoughts on an issue that I encountered:
The drive explained in this is a non-bootable drive. It is only a "data" drive.
Our backup program successfully backed up the "data", but not the partition table of a SSD. The drive uses MBR (not GPT).
We needed to do a BMR of the SSD (block-based backup) to a SATA drive.
I formatted the SATA drive with the default partition table (since we don't have a backup of the SSD partition table) and then did a BMR of the SSD "blocks" to a SATA drive.
The BMR completed with no errors, but when trying to access the drive would come up with "needs to be formatted before using". I knew this had to do with something regarding the partition table.
I used Gparted and could see it was NTFS with the GB's used / unused so I knew the data was on the hard drive. Its the partition table that is preventing me from getting to the data.
I used the utility "testdisk" and could see there was a geometry mismatch on 3 items.
I used "testdisk" to extract the files off the SATA to external USB drive.
A lot of programs look for deleted partition tables or corrupted partition tables. But what happens if you just don't have the partition tables. What are the steps to manually creating the partition table.
Do you think going from SSD image to a SATA drive is possible? Or is the geometry an issue when it comes to BMR to dissimilar hardware?
Thoughts on why I couldn't get it to work? Extracting the data is not the ideal route.
