The VAIO VGN-T350 is a notebook computer designed and distributed by Sony.
The hard drive on your Sony VAIO VGN-T350, which is the unit that stores data, consists of many clusters of data that can be rewritten with new data.
If you are looking for a memory capacity upgrade, or if your old hard drive is having errors, it's time for an upgrade.
Upgrading the hard drive on your Sony VAIO will require the use of a screwdriver and will take you about 30 minutes to complete.

Turn off your Sony VAIO VGN-T350 and remove the power cord and any other peripheral components.
Turn over your Sony VAIO VGN-T350 and locate the hard drive chamber on the bottom of your laptop. It will be clearly labeled.

Use the screwdriver to remove the screw holding the lid in place.
Gently lift the hard drive and its cage away from your laptop and disconnect the data cord.
Remove the four screws located at the corners, and then remove your old hard drive from its cage.
Place your new internal laptop hard drive into the cage and replace the screws.
Connect the data cord to your new hard drive and place your new hard drive into its chamber.
Close the lid and replace the screw to complete the operation.

Try deleting partition(s) and re-creating. This problem has been around for a while. It could be the hard drive, but most say it's the disc.

below is a link for a 320 gig hard drive for your model, i hope this helps

system not found in my experience generally leads to a damaged or loose hard drive, try to open the cover at the bottom side of the machine, and reseat the hard drive, if it still says system not found, get a 2.5 inch drive case, put your laptop drive in the case and connect it to another machine, if you can access the drive great! save all your files and once complete return the drive to your machine and try to reinstall the OS from a dvd then reinstall your files.. and if still having the same problem replace hard drive thanks.

Try google your question, I found this site for you http://repair4laptop.org/disassembly_sony.html

you can try to go to bios pae and check if the system can detect the hard drive.If not you might need to call call Sony to check if the system is still on warranty so that they can replace the hard drive free of cost if not you might need to replace it with a new one

Save Data if possible.

Use Restore System; Restore Computer to Factory "New" Condition.. Sont Vaios have a Key Prompt which you hold down while booting and the Replacement Software already on a Sector of the Hard Drive. Check THe Manuel for this OR CALL SONY CUSTOMER SERVICE AND JUST GIVE THEM THE MODEL NUMBER AND ASK THEM WHICH BUTTON YOU PUSH ETC TO RESTORE THE COMPUTER TO "FACTORY CONDITION"

hard drives dont bring internet? unless i am missing something here. hard drives are to save data into.

I want to get all Drivers of Sony vaio....
