access denied in vista 64 bit

Apparently I, logged in as administrator don't have the authority to copy and

paste files from one hard drive to another locally on my computer.

I have a dual boot system with vista home premium 64 on c: and xp home on E:

and I use D: for data files. I have 3 wd raptors in a raid 0 array

partitioned roughly in half with vista on one and xp on the other and a

separate hd for the data. Vista bsod'd and crashed and corrupted ntldr and

xp will no longer boot up. I had my email set up on xp. Lots of email. From

vista I tried to copy and paste the email data from where it is stored on the

partition with xp on it to my data drive to no avail. PERMISSION DENIED. I

tried taking ownership of the directory where the data is stored and the

directory where I was going to paste to, I shared all drives and directories,

I gave full permissions to ALL USERS, I tried safe mode, I used the command

prompt, nothing worked. It was always PERMISSION DENIED! The directory the

emails are stored in (outlook express) is a read only directory and when I go

to the properties of that folder and uncheck the read only box and click OK

it just reverts back to read only. Next time I check it's back to read only.

What's with all this crap? It shouldn't be this hard (or impossible?) to do

something this simple. If I don't have access to my own files on my own

computer then who does? Is this some kind of sick joke? I've been working at

this for the last 6 hours and am now thoroughly disgusted!
