I have meet a strange situation on reading a preamp value.

If i read preamp value from terminal (CTRL+L) I have a result like: 73 03
Instead If read rom via bootloader (or same using external reader) result is 03 73

Something wrong? :shockable:

In attach 2 log of same disk ST500DM002-1BD142

In ROM the data is stored in little-endian format.
So swap the bytes and you will have the same type, as from terminal.

Thanks for useful info but.............

Other disk: ST9500325AS

Preamp by CTRL+L -------> 5A 15
Preamp by BootCode -----> 00 54 :shockable:
