I have a multiple hard drive system with Windows XP installed on one drive, and Windows 7 installed on another separate physical drive. Each OS sees the drive it's on as "C", so depending on which drive I boot to, the Windows drive is "C" and the other windows drive is "B". I also have a couple of other drives with letters that stay consistent between OSs that I use for storage. Everything has worked wonderfully for months, but it seems I just broke it. Here's what happened... Windows 7 is the newcomer to the system, and I still only use it for a couple of programs, doing most of my work on XP. Usually when I want to share a file between OSs, I put it on "D", and access it from there. Recently, however, when working in Win7, I desparately needed a file that was in XP's "My Documents" folder on what Win7 calls drive "B" (which is, of course, drive "C" when I'm running in XP). When I went to grab the file, Win7 told me I didn't have proper permissions to access those files, and asked if I would like to have that access. I foolishly said yes. Win7 gave me access to the files, but now when I try to boot the WinXP drive, when it gets to the part where I think it should be loading drivers, I get a constant string of "Delayed Write Failed" errors and XP won't run. XP will successfully boot into safe mode, and all of the files seem to be where they should be, so I'm guessing Win7 did something to usurp control of the files that XP needs, and won't let XP access them anymore? I'm hoping there's a relatively simple way to fix this, but I'm still new to Win7 and have no idea where to start. Any help would be greatly appreciated!
