From the Above Errors I changed HM to 01 01 02 03. After changing this head map getting the Same Errs as above

I can read all System Files from H1 without any Err. Then I I tried to read Copy 0 got Err

I tried to write copy 1 sys files to copy 0, all goes well. After restart getting the Same Errs So H0 has can't read but can Write.


Why when headmap changed to 01 01 02 03 it tries to read Err from H0 ?

if you change hm to 1123, nothing gets written to nor read from H0. If you write, you likely overwrite something on side 1 with wrong data. Any read attempt from H0 will result in an error coz drive will try to read it from H1, which will obvously fail.
Moreover there's a good chance that a head/surface damage will stay unnoticed until the surface damage is serious enough to make problems on reading other surfaces.
So these head map changes must be used very carefully, i had a lot of drives that others tried to recover by changing head map and finally resulting in serious surface damages. Yeah, it's a few clicks but easy to set up for a disaster :s

After Changing HM to 1123 I can access UA sectors with very very slow as well as red and yellow blocks equally with Green.

My question is after changing HM to 1123 I can read sector 0 with Sector Viewer it is 55 AA as well as Last Sector . how it is? if H0 is blocked then sector 0 will not be accessed usually( From My Previous Experience)

IN DE HM creation shows sector 0 belongs to H0.

If anything wrong in my assumption pls clarify
