Dear All: My computer is Dell OptiPlex GX280 >From the specification on http://www1.us.dell.com/content/products/productdetails.aspx/optix_gx280?c=us&cs=28&l=en&s=dfb the hard drive is Serial ATA 40, 80, 160 and 250GB 7200 RPM hard drives with S.M.A.R.T. II To install Linux, I want to add a hard drive. The Dell website recommended product is MAXTOR 100 GB 7200 RPM OneTouch II USB External Hard Drive $127.46 It is surprising that an external hard drive is recommended. But what is more confusing is this website, http://linuxmafia.com/faq/Hardware/sata.html Seems serial ATA is not supported by Linux. So probably I have to buy a USB external hard drive. I wonder if Fedora support serial ATA or external USB or neither? Many many thank, HS
