Eu tenho uma unidade SSD morta. O BIOS não consegue lê-lo, o Linux e o Windows não conseguem lê-lo. Parece que o controlador não está completamente morto (ele se identifica).
Existe alguma esperança de recuperar os dados na unidade usando métodos suaves (sem anular a garantia)?
Não há nada de essencial lá (eu guardo vários backups do material realmente importante), mas seria bom ter as outras coisas de volta (savegames na maior parte, não é grande coisa, mas é um tipo de dor), e eu acho uma vez que eu RMA, ele será ido para sempre.
Hotplugging (via gabinete externo) produz a seguinte saída do dmesg:
