Hello guys,
thank you for any help.

So my hdd Seagate 7200.11 1 TB died recently and i admit i must have screwed it up.
Now im using a UART connection to repair/refurbish it.
Let's assume that data is not important.
What could be the best way to proceed? I dont want to spend money on it possibly.

Some actual details of what you did that "screwed the drive up" would be helpful.

I pretty much tried every single command,

1.I cleared the smart (N1, i4,1,22)
2.Spin up and down works
3.I followed the LBA0 guide (not BSY since when i use the paper to isolate the chip i can't communicate it seems)
4.I then used the hard format m0,8 .... but at 3% i receive bad sectors errors everywhere

My firmware is still CC1H and not SBD15 or similar
HDDGuru Low level format tool gives I/O error 1117
I haven't tried mhhd yet

I think that everything has been generated by HDD Generator, i think it screwed everything up when i tried to repair sectors since the hdd was really unresponsive with lots of dead time (stuck at 100% usage)

So is the constant read error associated with a broken drive's heads?
That's strange because some sectors are read correctly

HDD Regenerator = HDD Destroyer. It's not for data recovery, even their own disclaimer says that. It's for refurbishing drives with a few bad sectors. Drive is toast, toss it.

Ok so last question, could you link me an explanation about the structure of the low level sw (in general), like what is F3>/1 /2, the overall design behind an HDD.. Is the F3 Arch a standard?

Thank you for your help,
