Hello everyone,

I have a Seagate 2.5" 320 GB model ST320LT012 (Laptop Thin HDD), which came to me with stopped heads on the plates.
After gently removing the heads, the disk started normally (full ID, correct capacity) - but no access to data.

I started tinkering with filesys data smart (some errors).
Then I wanted to start over and rewrite all the sys files.

Now - after this treatment and restart - I am in total -... :oops:


Boot 0x40M [0x00000000][0x00000000][0x0002B55C][0x0002B55C][0x0000E0A0][0x0000E0A0][0x000395FC][0x000395FC]
SimError - Remaining in BootFW

I remember that a few years ago I had a similar problem after rewrite filesys and I somehow solved it, but now I don't remember...
The problem is that I don't have access to the terminal - but I have all SA copies (rom, id, ldr, filesys, mod,...)

I have replaced the heads and PCB (with ROM)
With the donor head we have similar messages with the same ending...

Boot 0x10M
RECOV Servo Op=0100 Resp=0005[0x00000000][0x00000000]
RECOV Servo Op=0155 Resp=0005[0x0002B55C][0x0002B55C]
RECOV Servo Op=0055 Resp=0005[0x0000E0A0][0x0000E0A0]
RECOV Servo Op=0155 Resp=0005[0x000395FC][0x000395FC]
SimError - Remaining in BootFW
Perform a double download without a power cycle


However, the head from the patient works without any problems in the donor.
Of course, shorting the reading channel does nothing...

It looks bad, very bad... :disabled:

Thank you in advance for your help and any tips.
Any man is liable to err, only a fool persists in error.

Your drive seems to have faulty writing. You need to feed a diskfw loader to start with...

The problem is still in Firmware, writing sysfiles, and changing heads are wrong move this LED:000000BD FAddr:00004C51 error has a solution. This happened because lack of Firmware knowledge to us. Seagate, WD or other hard drives brand didn't create HDD's for data recovery with in the mind and HDD's structure are their top secret, that's why we invent a new solution for every data recovery case arrived.

Tips

1. Seagate writing module and sysfile from even original backup FW uncheck Plist and other defects list until it is necessary or final option remain. I have experimented on lots of seagate families the command line of seagate work differently on every family.

2. Do not think about heads change until drives are spinning down.. or as you wish.

I will soon share my detail knowledge of both tips on separates topic when got some free time.

Drive is now pretty much screwed, albeit still pretty easy with right knowledge. Feeding Discfw is 1st step.
The bad thing is that if you cannot manage with the recovery, you cannot return it to the client unmodified either :s

I have an identical donor disk - ST320LT012 - I did the same...

I recorded the full service zone.

After uploading it back to the disk (via rewrite sysfile) - I have the same effect...

SimError - Remaining in BootFW
Perform a double download without a power cycle...

The problem is - that in the donor I can load the LDR into memory.

But in the source disk (client) I still have an error...

MCT Download error, Code = 0xXXXX9A03
Result............................................. ..... : Error
