Recovery ext4 partition and "read error"
Posted: 04 Jun 2016, 10:34
I have an HD on laptop Sony Vaio whith dual boot Linux Debian and Windows 8.1.
Afterwards the upgrade from Windows 8.1 to Windows 10, I'm not able to access in neither of two OS, I can only boot into Linux rescue mode
With Testdisk I can access to the data in Windows partition and Linux root partition, but not to the data in Linux home partition,
the error is: "Can't open filesystem. Filesystem seems damaged."
I also tried, without success, to repair the broken Ext4 Superblock with this guide: https://linuxexpresso.wordpress.com/201 ... in-ubuntu/
Any hypothesis about this incident? What's Windows 10 made to the partitions?
What can I do to access the data in the "Linux home partition" ?
In previous executions of TestDisk I recieved an error like this: "Read error at x/y/z (lba=n)"
Can I continue to use this HD in the future or should I buy a new one? There is a way to exclude a bad sector?
This is the content of testdisk.log (I was not able to attach as file, because error from forum)
Thank you for you time.
