Released in 2004, the Toshiba Satellite A65-S126 features a 15-inch display, a 60 GB hard drive, and DVD/CD-RW drive.
I was told my hard drive was bad if I found 1 on ebay is it difficult to replace
I suggest that you replace your HDD with a SSD, usually you only need to open a clap on the backside ... I asume it is the one in the middle above the battery slider labeld with a "3" !
