Can't backup Outlook PST to WD external drive

[NewHorizon1]

Just found this forum, and I'm REALLY hoping you kind folks can help me.

I'm running WinXP Pro SP3 with a WD 80 GB external drive.
For months I have been making daily backups of my Outlook 2003 PST file (learned this lesson the hard way) to the WD drive - J:/. For some unknown reason, the drive letter spontaneously changed to K:/ so that the backup couldn't complete. No problem, I thought - I changed the backup options to the new drive letter K:/. However, now when the backup kicks in, I get the message to Insert disk in Drive J:/ and also this Windows-No Disk error: Exception Processing Message c0000013 Parameters 75b6bf7c 4 75b6bf7c 75b6bf7c

I tried disconnecting and reconnecting the WD drive - no change.

I've made no major system changes, just normal Windows updates and one QuickTime update - but I've since uninstalled QuickTime altogether thinking this might be the cause. It didn't help. I'm also running Norton Internet Security 2009.

Any ideas? I'm starting to worry b/c I can't do my backups.
Thanks much,
KG

Are you inserting any blank usb, photo sticks, detachable memory cards or usb drives? Then Windows attempts to index it. Turning off the indexing should help prevent this problem from reappearing.
