I actually just had a similiar case; although the drive was a different model 500IJ (Spinpoint F1 series)

The drive had a nice ring around the landing zone area; which turns out was also the SA =(

I hate giving customers bad news

Basically what I think happened was the unit was in a buffalo NAS unit, single drive; and the drive was either knocked over, or there was a random mechanical failure/ head crash and because it was a nas, it was probably left on overnight or something, and was left to grind it's way down (the nas wasnt being accessed which is why the ring was only in the landing zone area).

I wasn't sure if the SA was in the damaged zone; so i attempted a head swap hoping as long as I could identify it and commene imaging quicky the heads would not touch that zone enough to cause severe damage, but unlucky for me it looks like the SA was in that zone =(

The ring on that drive seems much thinner, so your chances may be much higher, especially if the SA is not on the inner tracks.

*edit* forgot to mention; the tool needed is a HEX screwdriver.

Depends on where the SA is.

Never tried on a Samsung.

Do you have a parts drive for it? If you do then just open it up and start it up while it's open. Watch where the heads travel to and viola you've got your SA location.

*Open it in a clean room and follow all of the normal precautions* Though I didn't think I had to say that.

Hi to all!

more information on this case…

this hd fell, was used external…

After exchange of heads, hd is not ready… first increased the limitor to prevent that heads passed for risk…

later I was diminishing the limitor until the normal position came back… but exactly thus it did not read…

I believe that with this fall disks if had disaligned…. all exchange of experience and appreciated here…

do you know if the heads on the other side are untouched.
as its more likely they have damaged the platter too.

can you not do a reverse copy of the drive ?????????
