Hello, and Welcome
You can either remove it or leave it in place and use a small linux distro like Puppy to backup your data to a USB external or flash drive. For that computer I would recommend Puppy 5.2.8.
Burn the iso file in Windows 7 by right clicking and selecting Burn Image. If you do not have Windows 7 you can use Imgburn or isoburner to burn the disk. Boot the Puppy disk and when you get to the desktop you should see the hard drive of the Acer labeled as sda1. Click it once and a green dot will appear next to the hard drive icon and the File Manager will open. Attach a USB flash drive or external drive. A USB icon will appear on the desktop. Click once on it and another File Manager will open. Browse the hard disk on the Acer and select files by left clicking + Ctrl. You can select files and folders. Drag the highlighted files/folders over to the File Manager of the USB flash/external drive. A small dialog window will open asking if you want to copy or move the files. Select Copy.
Here is a guide that will help. Do not bother doing the diskfix at shown in the guide.
Here are instructions for removing the drive. Starting at page 66. It's for the 3600GT but it may be similar.
Edit: Service Manual. See page 82
