Hi, I have a Sony Vaio model SR150FN and I want to install a new TOSHIBA 500GB HD model MK5076GSX, the problem is that the BIOS can't see it, I put the HD in an external usb case, created a 500 GB partition, formatted that partition with quick and full format, took a long timetoo, and after that I made that partition an active one, but still the BIOS can't see the disk, Do you know why? Best Regards

Contact Sony support, you will need to provide valid proof of ownership. Computers Support

Get the disk copied to a new one immediately. Make a backup too.

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.

Restart your computer
during the boot process you will see on the screen to press a certain key usually delete or F2 to enter setup
Press and hold that key during the boot up process to enter BIOS
if you need to change any of the settings using the arrow keys you can load failsafe or optimised defaults
hope it helps you

According to the detailed specs on that model, it came with a 60GB ATA-5 EIDI hard drive. therefore, you can use any ATA compatible (ATA-5, ATA-6 or ATA-100) EIDE/IDE drive that has jumpers enabling you to configure the drive as "Master". Western Digital Blue Scorpio and Seagate Momentus lines both have models that will fit the bill. You can find those drives at your neighborhood BestBuy or Staples pretty easily. I don't know if the A25 BIOS supports 48-bit logical block addressing (LBA), in spite of what toshiba says, If it only supports 24-bit LBA the maximum drive size is 137GB. If it supports 48-bit LBA then you can go as high as you can find drives available; usually 500GB. I suspect that it supports 48-bit LBA because various online vendors list up to 250GB drives for that model. The most important thing about the drive, though, is that it MUST be jumperable as 'master'. A cable select only drive won't work. Both the Western Digital and Seagate EIDE models have jumpers. hope this helps but if you need anything else just ask:)

Hi,

Ur right about it! When changing ur OS, u have to get new drivers for ur mo board and utilities( Audio, video, Network Lan, USB, and upgraded Bios).

Better go to Sony Vaio and download the drivers for the new OS!

El problema puede ser que la programacion del audio tiene que se reinstalado. Te consejo que vajas al sitio del sony y lo bajes.

name and brand of ur laptop.U need to go the corresponding website for example asus.com/toshiba.com.When u are in the look for word download driver or word support.Then the model of your laptop as well as the name.Then follow the step.

what are the jumper setting on the hard drive. make sure the old one is the master and the new one the slave.
