I'm fairly certain that when you boot the liveCD and then choose to install the system that it goes through the normal Linux install process that includes formatting the drive. Have you run the Linux software to check the drive.. Disk Utilities, check disk? When my Linux EXT4 file system became corrupted, the Linux Check disk software failed the disk during tests. But then after reformatting the disk in Windows I was able to reload the LinuxCNC image I had made originally for this system. I just went and checked this same disk again via the Linux Check Disk software and the "Read Smart Data" shows that the disk has 93 bad sectors which is more than the Linux threshold of 36. So while apparently Windows has no problem continuing to deal with a disk with 93 bad sectors, perhaps Linux does?? You mentioned "systems", do you have other systems with the same software on them such that you could swap the drives, copy the LinuxCNC configs back and forth and see if the problems sticks with one of the drives? Your issue sounds like a disk related problem to me. I'd try swapping drives and configurations first to try to narrow the problem down to one drive if possible.
