Samsung Bad Head

Postby pclab » 26.03.16, 18:23

Hi Guys

One question/doubt please:

I have this Samsung that does this log:

The H1, does it mean head 1? Could it be only head 1 bad?

I have tried to do a Initialization RAM Headmap changing, but I get errors and can't start it....
Any more ideas or head swap is in order?
Thanks

Hello,
According To My Experience With These Drives Either System Head 0 or 1 Is Faulty Mostly Or The Topest Head

Hi PCLab,

Actually Amarbir is right, usually 1stGrayErr message stands for weak heads and according log it's head0 and head1 (system heads).
I suggest you firstly write burn if it exists for your drive model. If burn wouldn't help or it not exists - try to make hotswap to get access to modules and check them.
If even hotswap didn't help - it's 100% hardware malfunction and you need to try with donor parts.

Pavel ,
I Have Never Tried Burn Resources .I Understand Main Code Is For Making The Drive Run s It Should Be What Do Burn Resources To

Burn resources - the set of test microprograms and modules necessary to pass the Burn test as well as the Main Code portion of a drive’s firmware.

There are some types of some Burn resources:

Main Code – main portion of the drive firmware; the resource typically contains overlays.

H/T Code – auxiliary test microprogram used to disable heads, check drive components, perform approximate configuration of adaptive settings and build the service area “from scratch”. Resources of this type contain no overlays.

Burn Code – the main test microprogram used to test the drive components and generate translator modules, it may contain overlays.

H/T Burn-In Code – the main test microprogram used to test the drive components and generate translator modules. Its difference from Burn Code is in the fact that it combines the functions of H/T Code and Burn Code. H/T Burn-In Code of classic drives always contains overlays, in Trinity drives the H/T Burn-In Code contains no overlays.

FFlash – is an auxiliary test microprogram, its difference from H/T Burn-In Code is in the absence of overlays. It is used to disable drive heads, for partial building of the service area or obtaining access to the service area before the Burn test begins.

Overlay (Burn overlay) – the code portion of the main test microprogram written to disk surface. Burn overlay of classic drives is stored in the OVERLAY module, Trinity drives store it in the BOVLY001 module. Please note that Overlay presence among resources indicates that the image of the main Burn Code or H/T Burn-In Code contains no overlays.

Burn-In Script – the module containing a script for the main test microprogram with the list of procedures performed during the Burn-In test and their parameters. Burn-In Script in classic drives is stored in the BISPT modules, Trinity drives store it in the BINEWSCR module.

Geometry Script – a set of geometry parameters used by the main test microprogram while generating the zone allocation table. Classic drives have no such resources because their content is integrated in the main test microprogram. The script is stored in the GEO_00 module.

Has anyone seen this terminal output before? Are there any recommendations on the issue I'm having? The drive just spins and does not come ready.
