I've got a crazy problem, which I've already described in reddit: https://redd.it/4pj8t3
On an older computer without internet, I was still running Windows XP. I wanted to migrate to Windows 7 and try the free upgrade to Windows 10 before it expires.
I've installed Windows 7 to a new partition on the first drive (I didn't update the old XP, but took an image copy of course). Dual-boot works fine.
But I was shocked what happened to the Western Digital RED 3 TB (typo in the picture, hehe) after booting Windows 7: the partition table got smashed:
After quickly booting back into Windows XP the disk and its partitions returned without a problem! Hey, what's wrong here?
Let's see what TestDisk says:
Code: Select all
TestDisk 7.0, Data Recovery Utility, April 2015 Christophe GRENIER <email@example.com> http://www.cgsecurity.org Disk \\.\PhysicalDrive3 - 3000 GB / 2794 GiB - CHS 2907010 16 63 Warning: the current number of heads per cylinder is 16 but the correct value may be 255. You can use the Geometry menu to change this value. It's something to try if - some partitions are not found by TestDisk - or the partition table can not be written because partitions overlaps.
What do you think: can I completly destroy the partition and rebuild it without losing any data? To be true: I don't have the capacity to backup 3 TB, but only the most important files.
