I recently installed a bigger hard drive on my old 133 also. I used ezbios and was able to get both drive operational. But I encountered another problem which I'm hoping someone else has run into. I found that if I write jpg files to my A drive, there fine until I remove the disk and reinstall it. Then those jpgs are some how corrupted. The picture is distorted, wavy,kinda layered looking. I managed to bipass ezbios on boot up and copyied the same files with dos commands, and the files were fine. So is there something in ezbios thats hosin up my disk drive?? Thanks for any insight!
