Hello dear freands, have a good time;
I deal with seagate hdd model ST4000VX005 that gives no host fis ready error and stand in busy possition, i tried to read sysfiles 1B, 35, 28, 93 via terminal, and could read sys file 35, 93, 1B, but sysfile 28 dont extract,
How can solve this problem?

Of course, filesystem 28 is also read, but all its sectors are 0 or F.
