The current bootable HD will be the main HD and still boot. When adding the 2nd old HD, if need be, claim ownership. If you have no need for any data from the old HD, you can format it and then prepare for its use. HOWEVER, the safest way to do this is to connect the old HD alone. Disconnect the new PC HD, entirely(no need to remove it). Attach the old HD and using either freebie KILLDISK or DBAN pgm. wipe out/clean the old HD. Once done, you can return the new HD and old HD into PC. The old HD needs to be formatted, do so. Use the disc management tools under the administrative tools area. Amke darn sure what HD you're working on. Does this answer your question?
BTW, what does your new PC consist of, because it should be able to handle larger than 500gb HD installed. Something seems amiss here.
I need some hardware help. I had a hp pc that I fried when I attached the power chord. The motherboard was fried. Apparently, the power button was pressed and the pc was on and as soon as I attached the power chord, the pc was history. Anyway, I still have the old sata drive. The drive had Windows XP installed on it and alot of my files are still on it.
I would like to attach the drive to my new pc. However, I am not an expert and I have some questions:
my new pc has an sata adaptor and an extra bay and the motherboard supports hd up to 500GB. I have only an 80GB drive now and the sata is 200GB so I am safe with this topic. However, I had previously tried to install a dvd drive to another computer and now it will not boot so I am afraid to try the drive installation.
does the drive need to be formatted? I was thinking that the pc will detect an os and give me an option to boot either drive. I am confused about the fact that the ide drive has an os at c: and the sata also has an os at c: will this cause a conflict? if I attach the drive to the sata connector and attach the power then reboot, is there something else that I should do?
any help is most appreciated.
