Helios 2.5 showing head map 0 1 3 4 5 0

[Issam]

Hello
this drive is USB, with damaged rom, I could get the rom fro SA and attached sata compatable pcb, now the disk is showing readiness, and correct every thing, i could backup all SA.
The drive has 6 heads , 0 1 2 3 4 5. The drive can clone from heads 0 and 1 only (correct data) , from 2 3 4 5 no clone at all. When i press RAM head Map it Shows 0 1 3 4 5 0 order (NOT 0 1 2 3 4 5). When i do head map editting to default it access the SA, if i put it to "from Map" the disk does not show readiness at all, I admire if some one can help
Thank you
