In my thread below titled WinXP won't start, I went through all the steps that I tried. It begain with my son bringing his computer to me with a black screen that stated "Disk failure, insert system disk.. When inserting a Win XP disc, it would go in to setup and return the error that the disk was not accesible. I went on to put the hard drive in my computer as a slave and it in explorer in only showed one folder and it was Recovery with nothing in it. I cloned my hard drive to this hard drive and then removed mine and this hard drive would still not boot. I tried formatting the harddrive while it was in my computer and it stated that "format was unsuccesful and that the disk appears to have failed and may need replacing". Put it back in the original computer and it boots to a screen that says choose command prompt and run scandsk. While trying this it states windows is shutting down to prevent harm to the computer. Keep in mind that his Restore disk are about 500 miles from here and I will be going there in two days. Thus my question as to they will work with a new hard drive. Any suggestions, if you think the hard drive is OK. Please see my other thread for details. Thanks.
