Those two lines are debugging code you added, right?
Yes, sorry about that.
sectnum = (u8)((lba % id[ATA_ID_SECTORS]) + 1);
cylinder = (u16)(lba / (id[ATA_ID_SECTORS] *
id[ATA_ID_HEADS]));
in isd200_scsi_to_ata() because it must not be called before isd200_get_inquiry_data()
has completed.
It can't be; isd200_get_inquiry_data is called by isd200_Initialization
during probe before any SCSI commands are transmitted.
So, you are concluding that the bisection is spurious because
without that patch the SCSI layer would see a capacity of zero
and not even try to read anything?
