Hi Bake, tank you for your replay, I really appreciate it!

I did

/usr/local/bin/ddrescue -r 0 -R -n /dev/sdb /mnt/tmp/temp/imagefile
/mnt/tmp/temp/image.logfile

Press Ctrl-C to interrupt 
Initial status (read from logfile) 
rescued:         0 B,  errsize:   9223 PB,  errors:       1 
Current status 
rescued:         0 B,  errsize:   9223 PB,  current rate:        0 B/s 
   ipos:         0 B,   errors:       1,    average rate:        0 B/s 
   opos:         0 B,     time from last successful read:       1 s 
Finished

--------------------------------

and also:

/usr/local/bin/ddrescue -r 0 -n /dev/sdb /mnt/tmp/temp/imagefile
/mnt/tmp/temp/image.logfile

Press Ctrl-C to interrupt 
Initial status (read from logfile) 
rescued:         0 B,  errsize:   0 B,  errors:       1 
Current status 
rescued:         0 B,  errsize:   0 B,  current rate:        0 B/s 
   ipos:         0 B,   errors:       1,    average rate:        0 B/s 
   opos:         0 B,     time from last successful read:       1 s 
Finished

------------------------------------------------

so no success there.

If tomorrow ddrescue don't read it, and I don't find an other potential
solution, I'll have to consider one or more of these suggestions =(


Thanks again! and if you have an other idea, let me know!

Notes:
1. I use ddrescue 1.15
2. The disk is seen during boot, but its capacity is not detected.
3. This disk is one of two identical disk SAS connected. I tried connecting
it to the other SAS port. Same result. The second disk is OK, but all the
important data was (is) in the dead one.
