When i disassemble it, i took the hardisk and decide to use it as my network storage in my dsl 2750u..
this is how i do it:
1: put your hardisk in usb port at your dsl 2750u
2: log in to your router and go to ADVANCE/STORAGE DEVICE/STORAGE DEVICE INFO to make sure your hardisk readable..

3: Make a username in ADVANCE/STORAGE DEVICE/USER ACCOUNT and create your username/password by click ADD and insert desire username, password and repeat your password..

4: Log out your router and go to 'my computer folder' and type \\{your router ip} just like this
eg: my router ip is \\4.3.2.1

*common mistake: dont use /, but use \
5: hit enter and you will be prompt with network password, just fill it with your username and password that you created in your router in step 2 and if it ok you now can see your hard disk content just like this:

Done.. good luck!!
you can also use your pendrive, card reader!
