I have an XP computer sitting here, although I have not turned it on lately. It is SATA and NTFS in XP because without looking I am pretty sure. I had an old harddrive which was 160Gb I bought a new harddrive which was 500Gb both SATA on the motherboard. The only difference I think is that the SATA runs at 3Gb/second whatever it is transfer rate, and the new boards including my Windows 7 runs at 6Gb/second whatever it is for transfer rate of the bus on the mother board. The memory is faster and the processor is faster, otherwise besides the OS, that is about it for the last 7 years on a computer.
no A floppy drive on either computer and DVD drivers are one master drive and on a different interrupt and the harddrive is on the other interrupt as a master.
(I do have a ms-dos partition on my old XP computer for some old ms-dos games and that can not be done with Windows 7, that is why I still keep my XP computer around). I have games and some programs that I could run on either one, and some games that will not.
I took computer courses, but that was years ago now.So all I am saying is check out both computers take it into a place and pay to have it done. It is called an economy!.
(before I turn my amp and guitar way up in volume and wake up the dead with it blaring out into the neighborhood).
(no, not really!)
Oh, I have a couple maybe of USB 3 ports on my new computer, otherwise the USB ports are 2.0 version just like my old computer. I took my USB audio/interface, plugged it into my new computer from my XP computer (it does not have a sound card now until I put one in) and it works in Windows 7.
I can take the new old harddrive out of my XP computer and put it in my Windows 7 computer as a slave harddrive, but since I also bought a new one (same size) I still have to do that, because I may yet use my XP computer, and if I don't I can take out the fairly new harddrive and stick it in my Windows 7 computer and have three harddrives in it, and the DVD recorder/player. I can take the DVD (since it is newer the old one bit the dust) out of my XP computer and stick it in my Windows 7 computer also since it is a standard device, Windows 7 will have the drivers for it included with the OS.
Windows XP (64-bit) and Windows 7 (64-bit) and Vista (64-bit) are all based on the original 64-bit computer OS system, which is that funky Windows 2K. Of course they had 32-bit also which is my old computer, but Windows 2K was the first actual 64-bit instruction OS.
And even on my Windows 7 computer I have 32-bit programs running like Firefox and anti-virus, because not all the programs are 64-bit programs.
Think I will go and eat!
