Re: USB HDD ERROR

That's good news. Interesting that one shadow failure would cause another,
but that's a worry for another day.

Dave,

The server is functioning normally and the RAID 5 array is normal as well.
The messages that appeared in the Event log were as follows:

The shadow copies of volume F: were aborted because of an IO failure on
volume F:.

The shadow copies of volume C: were aborted because of an IO failure on
volume F:.

Both errors are the result of the F drive. I'll test the drive on a
workstation. I don't think there's a pending disk failure however I'll
keep
an eye on the event logs.

I would immediately get at least one good full backup of that entire
system,
including Exchange and system state. Until you've diagnosed this, I
wouldn't use the USB drive you had the problem with for anything
including
this backup. Then if you have a diagnostic app from the server
manufacturer
(such as Dell Open Manage), I would run all the RAID and hard disk
diagnostics. Then I would run a chkdsk /r.

It's a judgment call whether you do all of this now, or leave the server
in
production to the end of the business day today. I would do the backups
now
without question, and if the server is logging disk-related errors, I'd
do
it all now. If the server is functioning normally and not logging
errors,
you'll have to decide whether to wait or bring the server down now (the
diagnostic app might run with the server in production, but chkdsk
won't).
But in either case, when there's the possibility of disk failure, you
need
to act rapidly, as they often don't give much warning. It's possible
that
this whole thing is a glitch from the USB drive, but with errors reported
on
C, you can't take any chances.

Hello...

Had a major system problem this morning. At 12:45 am this morning the
system
encountered an error while backing up the the USB HDD. (see below)

Event Type: Error
Event Source: VolSnap
Event Category: None
Event ID: 14
Date: 10/9/2007
Time: 12:46:01 AM
User: N/A
Computer: Server
Description:
The shadow copies of volume F: were aborted because of an IO failure on
volume F:.

There was also an entry referrencing the C drive aborting shadow copies
as
well.

So... when I arrived this morning nobody could log on to their desktops
and
the server would not respond to the CTRL-ALT-DEL command. I tried to
use
RWW
and RDC from my Windows 2003 member server. Neither worked. System was
completely halted. I had to force the server down and restart.

On the restart the system went through the post OK, but stopped with an
error message "Disk Read Error, press CTRL-ALT-DEL to restart". Did
this 2
times to the same error. On the third attempt I pressed F8 to check to
status
of the RAID. All drives reported OK. So, what disk error?? The USB
drive
was
not plugged in during these restarts. After pressing ESC from the RAID
status
check the system booted to Windows.

Not a great way to start the day. Why would the system freeze hard like
this? There's no backup log so not sure what haapened with the drive.
I've
been using the drives for several weeks now with no problems.

Any thoughts??
