I think it's highly likely Microsoft is trying to squish support for it. Same goes with XP 32 though.
Though I've personally only ever had a problem with a couple of wireless cards.
I ended up getting an Atheros-based wireless card specifically because I could get XP x64 drivers for it - and plenty exist (I think a lot of broadcom-based cards have XP x64 drivers too), though they are not always included with the cards. But you do have to watch for it sometimes, for non-common hardware.
On the other hand, non-common hardware is often the kind that's fairly cheap, and that you don't replace often. So it would probably be worth getting a piece of hardware knowing it will support XP x64, that isn't going to be replaced for a long time. (I paid about AU$25 for my wireless card, and am not likely to replace it for a while)
But for hardware from AMD/ATI, Nvidia, Intel, Via, Creative, Logitech, Razer, and pretty much every motherboard manufacturer I've seen, there are XP x64 drivers. And that's basically 99% of desktop systems which use 64-bit processors covered.
I've gone through plenty of XP x64 installations (including SP1 and SP2) with various hardware, and haven't come across that issue even once.
I don't want to call you a liar or anything, but you're the only person I know that's had that happen.
do a post check of me talking about this here since you going all out of the way to insinuate that I'm a liar. I'm not going to do it for you. at least 2 guys here talked about it when i mention it. I killed 3-4 hard drives on xp 64bit before I left it alone.
that was on 2 completely different versions of xp 64bit. I thought that particular first version was the problem so I got another one. I've have friends have the exact same issue. one didn't put it together that 64bit was the problem until i pointed that out to him. but I really don't care if you believe me or not.
check my my history here. I may be a lot of things but I was never a lair. when I gang banged when i was younger, that was one of the thing that made me so respected in the gang community. because most gang bangers lie, cheat and steal. I just beat up people. I was the guy that everybody want to leave their stuff with when they went to prison because they knew nothing would happen to it. i was also the only guy never to go to prison.
I was the guy that was once confront by 10-15 individuals who ask me was I then that was talking trash to them when i was with my posse. that happens a lot in the gang world. usually the guy that by himself will try to lie his way out of it before he get jumped because he want to escape.
I said yeah that it was me, then I got my beat down. why lie? it was going to happen anyway. but that little incident gave me more clout in the gang world. 1st thing first, I a man. the number one man rule is "your word is your bond"
I know that you new generation guys don't know any thing about that, but I do. so you could have kept that stupid comment to yourself, because it really wasn't called for.
just because you haven't encounter it, you think that I'm lying. why would I make something like that up. if you notice I said that it doesn't happen everything that you copy and paste, it just happen too often to be considered normal.
do like i do. i use to copy and paste on the 64 bit side on my dual OS because it could transfer files a lot faster. it still do. if you copy stuff to another ide drive you have no problem. I, got over 5,000 gig of stuff on my 4 house computers so it made sense to copy and paste my huge file collection in 64 bit. I try to have my music and video collection back up on every computer in case something happens to one of them. My only issue?
sometimes after copy to a usb drive when you think that it was done and you unplug the usb it would say delay write failed. when it said that in 64 bit the drive was officially dead. now there was a couple of times that I had that exact same error in 32 bit xp over the years, but the drive would still work. that file just wouldn't copied over correctly
you start copying huge files to a usb hdd on a continous basis in 64 bit, then you can see for yourself what happens.
