Hi Gunusha,

I do not recall where LBA is converted to PBA but you can follow from diskmech.c.

If you search for where diskacctime is called, you can track its inputs cylno, surfaceno, blkno, which all together form the PBA. Very likely that LBA is converted into PBA right before diskacctime is called.

double diskacctime (disk *currdisk, band *currband, int type, int rw, double reqtime, int cylno, int surfaceno, int blkno, int bcount, int immedaccess)

Hope this helps until someone else provides more accurate information.

Thanks,

Cagdas
