Recycle bin not showing deleted files for an external hard drive

Hello!

I work on a laptop and a desktop. I use an external 320 GB hard disk to save my files.
The laptop is running windows 7 home basic 64 bit (more than 2 years old) and The desktop is running windows 7 ultimate 64 bit (recently installed with formatting new pc).
The problem is..
If the HDD connected to the desktop and I delete any file from the HDD, the file appears in the recycle bin of the desktop but as I connect the HDD in laptop the files are not appear under recycle bin of the laptop. Likewise any file deleted from HDD appears in recycle bin of the laptop when the HDD connected to the laptop but not appears in the recycle bin when connected to the desktop.
Is it normal? I do not think so. If it is a problem then how can I correct it. I have tried windows troubleshooting -- performance check , HDD error check but no error can be find out in both computers.

Wish for your helpful suggestions.

I think this is quite normal if I have read your post correctly. When you delete a file from your external HD the deleted file get transferred to the Recycle Bin of the computer you are using. When you change the external HD to your laptop then there is no record of those files as they have already been deleted & would still be the Recycle Bin of desktop, unless you have deleted them from there.

The behavior observed is not an accident or a bug. It is by design.
This will not be apparent to many but each user account on a computer has their own private recycle bin. A file deleted by one user will not even be visible to another account. For security reasons this is a necessity.

In the current situation we have a file on an external drive that is deleted by a user while it is attached to a desktop. The external drive is then moved to a laptop. The current user on the desktop and laptop may have the same login name and password but to Windows they are completely different accounts. Windows identifies accounts by a unique number, not the account name. The name is just a convenience to humans who have difficulty remembering large numbers. As the account that deleted the file is not that of the laptop user the file is not displayed in the recycle bin. To do otherwise would be a serious security breach. That deleted file may contain sensitive information that should not be seen by other users.

It is important to remember that Windows 7 is not just a home operating system. It is also designed for business use where there may be multiple users on a computer and secure access to files is a necessity. At times this can be an inconvenience to home users.
