Gparted crashed during resize. Can I recover data?
Solution 1:
You can most likely recover your data using Testdisk - this free software can scan and recover partitions and has saved me from similar issues to yours before.
Depending on what happened during the resize, you may, of-course, also be able to simply USB Boot and read the data.
I do note that best practice would be to do a bitcopy of the drive before running testdisk on it, just in case it makes things worse. I've never lost data as a result of using testdisk, but block level operations of this type are considered fairly high risk.
