I did test again in a more controlled way as last test was done using 12VDC 1.2A switching PSU wall plug. Power cycling was fast, ~1 second off time, just disconnecting barrel connector and plugging it back right away.
Please note that I also had same result pushing reset button instead of power cycling. I did not test with other mSATA type yet. I did have same behavior with other computer using same Transcend disk on field. New test I did: - fsck my disk first (was clean) I did test again with a Insteak lab source set to 12VDC @ 5A, source is 0-18V 0-5A. I'm using 4ft 16AWG wire. And I do not power cycle or use reset button anymore. I just add "shutdown -r 1 &" to my boot script. So it boot Linux then wait 60 seconds then reboot. Gracefull shutdown/reboot. First test took 16 reboot to fail with grub error Second test took 76 reboot to fail with not boot device Then I have dd if=/dev/zero to cleanup my disk. And reinstall everything using lilo as boot loader. Same result first log: 29 boot to bootfail second log: 58 boot to bootfail I have full boot log of that available. NOTE: Everytimes that fail, it took 15 seconds to detect the harddrive.
