How long will chkdsk /f /r take on a 1.7 TB drive

Hi,
I have a Windows 2000 Advanced Server (with SP4) machine in our production
environment which is connected to a SAN storage. One of the drives in the SAN
(mounted as drive letter T on the server) is corrupted. The capacity of that
drive is 1.7 terabytes and there are about 3 million files currently on that
drive (used space about 1.2 TB). I would like to run a chkdsk on the drive
with /f /r arguments. Can anyone help me provide a rough gauge on how long
will chkdsk take to run on such a large drive? I know there will be a
significant downtime required, but I want to get a rough idea on how long
will that be so that I can tell my customers what to expect. Also, please let
me know if there is any better alternative that chkdsk for such a scenario?
Thanks a lot in advance.

My apologies, but I forgot to mention that this T drive is configured as RAID
5 on the SAN storage. And there are no problems with the disk itself since
the RAID manager does not show any bad sectors. The corruption problem is
with the file system and file allocation table, hence I wanted to run chkdsk.
I suppose since this is a RAIDed drive, I will not be able to run chkdsk with
/r option since the physical disk(s) are not exposed to windows in this case?
