I have a asus laptop with a 3to seagate hdd (st3000dm001) 3.5" 7200 rpm
Yesterday, I had an update from ubuntu which I installed as habits. My laptop crash as the battery was low, turned it on, if i'm right it was update from 16.04 to 18.04, I don't know if the crash occurred while the update or if it was fully done. (There were slight changes like the turn off menu with the update after reboot)
I closed my laptop, hence it slept, when I opened it again to turn it off, it was weird, wifi wouldn't turn on, shutdown item in menu in top-right hand corner was not working hence I shut it down using 5s press on power button
When pressed the power button to turn it on few hours later, it shows the asus bios screen then restart and again and again, not showing grub.
I can start with a usb live key
the hdd spin normally I hear/feel it
I tryied to plug in in another computer, which doesn't recognize it
In my bios laptop the sata port appears empty (I plugged it off and then plugged it again)
While running a live linux I can't see it
dmesg report sata port as dummy
I had with the usb test disk : comreset failed errno : -16
I don't know what to do more... Is my hdd dead while the head is still spining? If it's an os problem (software side, I think about faulty mbr) would it shows up while on linux live? What can I try?
Thanks for your help
