Problema 20260414
Default boot device missing or boot failed - the system cannot find a bootable drive
- try BIOS
- enter the BIOS using F2 after "Acer" logo is displayed
- go to "Main" tab
- make sure "Network Boot" is disabled and "F12 boot menu" is enabled
- toggle "UEFI" and "Legacy" and try to boot - leave "UEFI" at end
- under "Boot" tab, set "USB HDD" as first option
- use Windows Media Creation Tool -
download
- boot "Windows installation media" and select "Repair"
- when finished, choose "Troubleshoot > Command Prompt"
- "diskpart" + "list disk" + "select disk 0" + "list partition"
- boot "Mint Live USB" ("Integral" 8 GB USB)
- dmesg -i /dev/sda
- Gparted
- Discs
- "ping 8.8.8.8" despres de escollit la wifi (baix a la dreta)
- "sudo gdisk -l /dev/sda"
- repara repositoris :
sudo rm -rf /var/lib/apt/lists/* sudo rm -f /etc/apt/sources.list.d/* sudo nano /etc/apt/sources.list # Esborra tot el que hi hagi i enganxa exactament aquestes dues línies: deb http://archive.ubuntu.com/ubuntu/ jammy main universe deb http://archive.ubuntu.com/ubuntu/ jammy-updates main universe sudo apt update --allow-insecure-repositories sudo apt install smartmontools testdisk --allow-unauthenticated -y
- verifiquem SSD :
sudo smartctl -a /dev/sda Tipus de taula: tria [ EFI GPT ] si és un ordinador dels darrers 10 anys o [ Intel ] si és més antic.
Botons i LEDs al frontal
3 LEDs top left :
- Hard Disk / SSD activity (Cylinder icon)
- Power indicator (Light Bulb icon)
- Battery indicator (Battery icon)
Hard reset : hold the power button down for a full 15 seconds until the light goes out completely.
Then, turn it back on. This clears the power controller (EC) and often restores the LED to full brightness.
Com obrir-lo per accedir al disc SSD i la bateria
- unscrew 5+3+4 screws
- inserta una paleta de plàstic a la cantonada i fes que faci la volta
Battery reset pinhole
Small hole in the top of the back.
- resets the power management circuits
- drains remaining charge from the motherboard
While the laptop is off and unplugged, insert a paperclip and hold it down for 10–15 seconds.
Let the laptop sit for 5 minutes, then plug in the charger and try to power it on.

Resposta
Això és un diagnòstic definitiu.
El fet que smartctl reporti una capacitat de només 20 MB (quan un SSD M.2 hauria de tenir centenars de GB)
és el que anomenem en informàtica un "SSD en mode ROM" o "Fail-safe mode".
El model que apareix, PS3111, correspon al controlador Phison S11.
Aquest controlador és famós per un error conegut:
quan detecta un error intern greu en les cel·les de memòria NAND (o en el seu propi firmware),
es bloqueja i entra en un mode de recuperació bàsic.
Per això et diu que té 20 MB: no està llegint la teva memòria real, està llegint una petita zona de "seguretat" del propi xip controlador.
Dades perdudes: En aquest mode, l'SSD no té accés a la teva taula de particions ni a les teves dades.
Les dades encara hi són físicament, però el firmware del disc ha bloquejat l'accés per evitar més danys.
Si les dades no són importants:
El disc està espatllat físicament.
Aquests discs amb controlador Phison S11 que entren en mode 20 MB gairebé mai es poden reparar de forma domèstica.
Intentem formatejar-lo :
sebas@minie:~$ sudo wipefs -a /dev/sdb ; eliminarem qualsevol rastre de la taula de particions corrupta que té ara mateix
sebas@minie:~$ sudo parted /dev/sdb mklabel gpt
Warning: Error fsyncing/closing /dev/sdb: Remote I/O error
Retry/Ignore? r
L'error Remote I/O (Entrada/Sortida remota) en un disc connectat per USB sol ser el resultat
que la placa controladora del SSD ha perdut la capacitat de comunicar-se amb les memòries NAND.
En aquest punt, el disc s'ha convertit en una peça de maquinari inoperativa.
Que comprem ?
- SSD - SSD M.2 SATA 2280
compte "SATA"
compte "B+M key"
Amazon 31 € - RAM - 4GB DDR3L 1600MHz SO-DIMM PC3L-12800S CL11
Compte amb la "L" de DDR3L i PC3L : 1,35 volts en lloc de 1,5 volts
Comprar una per fer parella amb la que tenim es complicat.
Comprar dues ja no es tan barat
M.2 SSD 128 GB SATA III
