I don't know about you but I've never really done a home inventory. This may surprise you since I've had damage from a hurricane, a fire, and a burst water pipe. Each time the damage was not fully covered because I either didn't have the proper coverage or didn't have my belongings documented properly. Uhg...
I'm hoping that there won't be a next time. If there is, I'll be better prepared.
Several months ago I picked up a digital recorder at a thrift shop. the plan is to go room by room and do a sweep of the room. Recording what's in the room and then doing close-ups on important items. In each room, I'll have to open drawers, closets, and cubbies to expose hidden treasures.
Burning a copy to disk and storing it off site or uploading it to a remote storage site could help me back up any future claims. I'm also marking my calendar to update it twice a year.
The digital recorder can also help validate the shape things are in.
