First,I dont know much about computers. I need to extend storage capacity on my LenovoT61 2GHz T7300 1GB 32 bit, 68GB to at least 250GB to store and work with all my pictures I have made so far. I checked the lenovo website but cannot find enough information as to what internal hard drive would be compatible. I know there is place where you can enter product ID but it just doesnt work. Is there anyone who could point me at the right direction? Thank you, Tomas
