Mass storage for your notebook, a hard disk or a SSD
Laptop hard drive, SSD, IDE and SATA drives or storage.
One of the most common failures in a notebook is the hard disk, it is also one of the few components you can upgrade. Notebook hard disks fail more often than desktop hard disks.
Reason: simple your notebook absorbs more punishment than a desktop. You move your notebook continuously, where you go the notebook goes. I know you are careful with how you handle it but still it gets banged around.
So what can you do about the constant shock the hard drive gets on a daily basis? Not much, be more aware that the hard disk has your data and back it up often. Maybe make an image of the hard drive. To take the worry out of your storage maybe you should consider a SSD (Solid State Drive)?
The laptop hard drive is located in a bay in the laptop, Most have some shock resistance built into the bay. Some hard drives are easier to remove and replace than others. I have seen some hard drives under the keyboard, completely inside the case where you have to take the case apart to get to the hard drive.
You will need to go to the manufactures web site and do a search for your computer if the documentation that came with it doesn't show you where and how to remove the hard drive. Acer's are one of the 'no documentation' type of computers, all the manuals are ON the hard drive, what do you do if it has failed?
Once you have located the hard drive and understand how to remove it you just reverse the procedure to reinstall the replacement.
A word of caution: ESD will damage the hard drive the same as dropping it!
One thing I would suggest you do is to make a couple of images of your hard drive partitions. If you have a hard drive failure all your data will be lost, with an image of the OS partition and the data partitions (if your installer had the foresight to make two partitions on the hard drive) and a good back up, the failure of a hard drive will not be as catastrophic.
At one time when you sent a computer into IBM for repair they would wipe the hard drive and reinstall the OS, IBM has since sold off most of their laptop business so I don't know it this is still true. To save reinstalling all of your programs, finding those pesky cd's and keys you could restore your computer at least to the point of the image and then complete the restore with the backup.
