My client was having an issue when updating an existing pdf file in SharePoint on machines that is running Windows XP and office 2007.

Symptoms:
When you open a pdf file from a SharePoint library, make changes by adding/Removing pages, adding bookmarks and save the file. you notice a new copy of the file is created with a name that starts with “aaa” and without an extension. and all the properties of the original document are cleared.

Cause:
This error occurs when the save to the server is delayed because of the “Enabled write cashing on the disk” feature of the hard disk is turned on.

Resolution:
To resolve this issue, you need to turn off the “Enable write caching on the disk“. To do so, please follow these steps: (If you can’t see your Device Manager, please contact your administrator)

1. Open Windows Explorer.
2. Right click on My Computer and then click Properties.
3. Go to the Hardware tab.
4. Click on Device Manager.
5. Expand the Disk drive node, right click on the main hard drive and then click Properties.
6. Go to the Policies tab.
7. Clear the “Enable write caching on the disk” checkbox and then click OK.

After you complete the steps, you shouldn’t have any issues when you update files.
