With arrays, you don’t want to run a CHKDSK.  Instead, what you want to run is a consistency check.  This is done via the RAID controller from outside the operating system, or OpenManage from within the OS.  Issue with CHKDSK is Windows sees the volume, but doesn’t know it consists of multiple physical drives.  Doing a CHKDSK can actually cause array issues. This is why a consistency check is advised when drives are in an array compared to stand along.
This may be a ridiculous question, but . . .  I have a PE1950 with four MD1000 storage modules attached.  I have three virtual drives of about 12T and another (new) virtual drive of 24T.  Windows wants to run a CHKDSK on two of the 12T drives.  Assuming this process would take an extrordinary long time, I'm wondering if there is an alternative way to accomplish this process a) quicker and b) while the server is up and operational?  I simply cannot have the server down for the amount of time a traditional CHKDSK would take. Any suggestions anyone? Thanks, KBeau
Alternative to CHKDSK?
