Hi Roland, depending on the make of the problem hard drive you may have to use a drive formatting tool on it. here are the links to a couple of brands; http://www.maxtor.com/en/support/downloads/index.htm look for maxblast <http://support.wdc.com/kb.asp?p_sid=4_jxj7Xg&p_lva=78&p_sp=cF9zcmNoPSZwX2dya WRzb3J0PSZwX3Jvd19jbnQ9NTczJnBfcGFnZT0x&p_li=> I don't think PM5 will allow you to move the OS from one hard drive to another and keep the Master Boot Record in tact You would need Drive Copy or other similar product. I hope this helps. BTW what operating system? Mike ~ It is a good day if I learned something new.

We have the Creative SBLive Platinum Sound Blaster sound card. It was installed and worked perfectly two or three years ago. It has been through hard drive upgrades of copying all data to another hard drive several times. Then it had some problems develop slowly, one at a time. Finally, I went to reinstall, and it would not reinstall, or uninstall, and could not be fixed. I now have two or three extra hard drives to play with. I took one that had been my earlier Primary HD, and had these files goofed up on it also, and it would not uninstall or reinstall, but it would not matter if I messed up that HD trying. So I searched for and deleted every visible trace of all files. Then I tried to reinstall. It normally asks for the serial number, but it already had it from somewhere, and after clicking on the user agreement, it promptly refused to install but shut itself down. However, I was able to get a perfect fresh install on two other extra HDs, one a 2 gig and one a 6 gig, both in a primary drive letter. So my next 'trick' is I am thinking of using Partition Magic 5 to take the good install from one of these extra HDs, and move it into a secondary drive letter on another extra HD. Then that HD would be paired as the Slave drive unit with my current Master HD, and Partition Magic would be used to move it to a primary drive letter on the Master HD. I don't know if it will work, but that is the idea. But I sure would appreciate if anyone knows how to just 'fix' the Master HD and get it to take a reinstall, without doing a reformat of the entire HD, that is. Thanks.
