Write at sector level

NtDev_GeekNtDev_Geek Member - All Emails Posts: 102
Once I receive an IRP_MJ_WRITE with Byte Offset and Length, defiantly they
Belongs to some Cluster(and Sectors). Now as it is a write to some clusters
So it can be taken as granted that wherever write happened we can Consider as
Changes to a volume if i am a disk or volume driver.

with all the respect Thanks a lot.

    Only if the final status for the WRITE was success. If it failed for any reason below your driver then, the data may not be modified or partial modified.
