[eside-ghost] Hdparm y arranque debian

[IJ]

Aupa Borja,

     -k1 si me funciona

     setting keep_settings to 1 (on)
     setting xfermode to 34 (multiword DMA mode2)
     
     -K1 da input/output error

     setting drive keep features to 1 (on)
     HDIO_DRIVE_CMD(keepsettings) failed: Input/output error
     

     mirando la man del hdparm leo:
     
       -k     Get/set the keep_settings_over_reset flag for the drive.  When this flag is set, the  driver  will
              preserve  the  -dmu options over a soft reset, (as done during the error recovery sequence).  This
              flag defaults to off, to prevent drive reset loops which could be caused by combinations  of  -dmu
              settings.   The  -k flag should therefore only be set after one has achieved confidence in correct
              system operation with a chosen set of configuration settings.  In practice, all that is  typically
              necessary  to  test  a  configuration  (prior  to  using  -k)  is  to verify that the drive can be
              read/written, and that no error logs (kernel messages) are  generated  in  the  process  (look  in
              /var/adm/messages on most systems).

       -K     Set  the drive's keep_features_over_reset flag.  Setting this enables the drive to retain the set­
              tings for -APSWXZ over a soft reset (as done during the error recovery sequence).  Not all  drives
              support this feature.

       cuando dice soft reset entiendo que es un reboot, es decir, que
       si apagas la máquina totalmente y vuelves a encender ya no están esos
       valores guardados. De hecho lo he probado y no los guarda. No
       se si usando -K1 (a quien le funcione) los guardará.

       Sigo intentandolo con shell script, aunque me está costando.
