HI,
can any body tell me why we run SA FORMAT or FORMAT RESERVED AREA or SELF SA. and what we do after doing this ?
sa format and reserved area format.
when we disable head in head map we need to remove its adaptives also and set the adaptives of head 1 to work like head 0. for example
head 0 701 adaptives
head 1 702 adaptives
head 2 703 adaptives
now we are going to disable head 0 in head map now these are the settings
head 1 701 adaptives
head 2 702 adaptives
703 adaptives
now here many user ignor the point and hdd start clicking after power reset . after disable we need to move adaptives like this
head 1 702
head 2 703
0
now after reset power hdd show ready and cannot spin down
now next thing is to change region so that hdd work with 2 heads , when 3 heads thee regions are 3, after disable heads regions are still 3 . now we need to remove region of head 0.
now in some hdd format sa or format reserved area need permanent overlay (module number 11) upload it and format SA after it complete see regions now there are 2 regions. if hdd has one head also have two regions. format sa also need a quick sa list and save error in this list ( module 35)
next step is to upload 01 directory module now people write 01 and 35 together but it is wrong . why they write together because when they write 01 module the 35 show header error.
solution
in wdr open modules operation and click on road map . here wirte 01 and initialize it now it cannot damaged 35 module. now write 11 module and initialize it . now close modules operation and open it again and write all modules except 01 and 35 now may people reset power and hdd goes undetected like mackenly and mariner hdd and also jamica. now after upload all modules select 31 32 33 34 36 modules and clear all these modules now reset power.
next step
reserved area arco .
after all these steps we need to run reserved arco to set all things with these two heads in rom .
SELF SA.
now after running arco we need to run self sa. what self sa do ? it add all bad sector from firmware are and add it into sa list (module 35) and also genrate new 30 module . now again we need to format sa with hdd own rp list (35 module) after that upload 01 and initialize it then write other except 01 and 35 .
and clear 31 32 33 34 36 modules . cannot clear 35 number module
now hdd is ready to start arco .
now it depend on u that u run arco one by one . or run arco in pst sequence.
. here is the procedure of recyling the hdd with head disabling .
head disable and head depop are two different things.
Thanks
