[The Solution for Seagate 7200.11 HDDs]

Success full story, I am writing this to help if somebody have the same case.

FIRST THANK ALL THE PEOPLE FOR THE INFO, THANKS TO YOU I COULD RECOVER MY DATA

MANY THANKS !!!!

I have ST31500341AS, I own like 5 more HDD from this type and 3-4 from 1 TB from Seagate hope they will not show same errors, My BIOS is CC.. and used the drive for 2.5 years with no problems, and 1 month ago it simply disappears. I tested the HDD on different computers and on some BIOS doesn’t shows at all, in older ones shows but LBA0.

So I used

I have very similar case like v71 here is the post

I Bought a USB to TTL adapter. Installed HyperTerminal on Win7x64. Connected the HDD.

1. If any of the connections (motor or heador both) is covered HDD would not react at all to any CTRL-Z.

2. HDD does react to CTRL-Z only when both motor+head are in contact with PCB.

3. Hyperterminal reacts to COM4 (Thanks v71) on COM3 no connection

I could do the following

Rst 0x20M

ASCII Diag mode

F3 T>/2

F3 2>Z

Spin Down Complete

Elapsed Time 13.094 secs

F3 2>U

Spin Up Complete

Elapsed Time 9.071 secs

F3 2>/1

F3 1>N1

Init SMART Fail

LED:000000CC FAddr:00239CED

LED:000000CC FAddr:00239CED

After that restart And

F3 T>m0,2,2,0,0,0,0,22

Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 00, Max Certify Rewr

ite Retries = 0000

User Partition Format Successful - Elapsed Time 0 mins 00 secs

Zone re-format was skipped.

F3 T>i4,1,22

F3 T>

And restart again it worked, I could access my data and copy it,

Right now I am making RMA because the disk doesn’t pass short test on Seatools.

Hoppe they change it.

Again THANK ALL the people for the info in internet…
