    Default Can dual-boot Windows8 x64 and Windows7 x64 cause file corruption of NTFS data volume

    Hi all,

    I have Windows 7 x64 and Windows 8 x64 installed to separate NTFS partitions for dual-booting.

    On a third NTFS partition, I store my data files, including documents, my PST files, and software project files. For the most part, this seems to work fine. Each OS can see, open and save the data files without immediate errors. However, on at least one instance of rebooting OSs, chkdsk started up and ran on the data drive, finding enough corruption that it rendered a good deal of the files useless, requiring a restore from backup.

    I'm asking whether this occurred due to the dual booting, or is it more likely a hard drive failure? Should I be able to "share" the files between OSs this way, or does Win 8 modify the file in some way that is seen as corrupt from Win 7 (or vice-versa)?

    Hi Willy,

    The dual-boot is irrelevant. Win8 has not caused the issue. Many of us, including myself, dual-boot 7 & 8 & have separate Data drives. It's, really, an ideal configuration & Win8 did nothing/will do nothing to your Data drive. YES, the files can be shared that way & Win8 will not modify files such that they 'appear' corrupt. Take the Data drive out & hook it up to another machine & see what that gives.

    Cheers,
    Drew

    I have to second Drew's response. I also have Win 7 Ultimate, Win 8 RP and a separate data partition on my PC. Works great.

    Hmmm... you see I'm not so sure...

    Sorry... First of all ...Hi there... newbe here... sorry for resurrecting old thread, but... let me explain...

    I have a same set up as above, didn't think much and I used files logged on from both systems...
    ...now exactly same story... I've gotten chkdsk at boot time...
    ...let me first clarify one thing... win may not corrupt the files, but it sure does have some kind of different file structure...or something...
    Here is a perfect example.

    Some time ago I've been playing some game on win 7, then i wanted to see if this game will run on win 8 (or something, don't remember the reason)
    Now... after logging in to win 8 and running the game the save files appeared as corrupted in a in game menu I was like WTF right so I wen't back to win 7 launched that game and game saves were fine again... now I've checked it several times the location of the files was correct... I thought maybe permissions, so I changed permissions to allow anything and everything... no dice... they wouldn't start from win8... but the strangest thing is... that game wasn't even installed twice for each system. Both system could run it from the same location... and no problems... I mean...there is some kind of difference then isn't it? Quite frankly I don't know what to think about it at all, cauz' going back to to the chkdsk issue... if I run chkdsk in win 7, then it would ask me to run it in win8 as even eventViewer reported that the drive file structure has become unreadable... or something like that... It's been so long, I can't remember anymore... too bad I didn't save any reports. Ah well...
    So... I'm not saying, that I don't believe you guys, but there is some factor that "mixes" things up.

    Any thoughts?

    It is possible that game has not been updated for Win 8. The fact that it runs correctly in Win 7 using the same data would leave me to believe that it is a game issue rather than a Win 8 issue. There are some apps/games that need to be updated to run properly in Win 8. I suspect the game developers might be slow in updating to this new OS in the hopes some will purchase whole new updated games. Just a thought.

    That might be it... it does take time to learn new system strengths a weaknesses so you can't really blame outside devs, because there wasn't that much time.
    I also considered simple thing as different user name encoded within a save SID maybe, and that would be perfectly good explanation..... if I didn't have my "Trustee" installed on a third partition, and this one was a 32bit Great XP PRO... ohhh... if only it could support more ram and at least a quad core...

    You know what... it's just so messed up, that when throughout all that time and trying to make XP as stable as possible, and when we actually reached this point IMHO XP is THE most stable op system and even though I don't have much experience with linux based os I'm sure XP would easily hold it's own.... and now...
    Now... we're gonna get to do this all over endless patches and fixings, and improvement's...

    I mean ... darn... so far win8 isn't something I'm looking forward to as a replacement for "everything else"... for starters... it's just too darn restrictive for it's own good... who needs that much protectionwhen the way I saw it, win * was the worst virus, and spyware, and adware I have ever gotten... so in a way I'm kind of greatfull for the win 8 expierience which led me to this realization... what do I need AntVir for if i'm running my system on the biggest of them all. It blocked me on almost every step you can't do this , you can custumize that... no custom drivers either... unless WE approve it. And to get some wiggle room and go thru the darn Policy takes forever, plus you're never sure if you have set it all in the right space cause the same setting keep repeating forever... and after all that the darn thing won't even boot cause you missed some dependency and win 8 is VERY unforgiving in that.... bottom line is I threw out all my "Magic Software" disabled all MS protection and anything that had a word AUTOMATIC in it (don't get me started on that) All I have now is "free comodo firewall"( took some time to strip all the extra weight , occasional MBAM scan here and there, and I have a great running system. Should have done it years ago...

    And yes I do realize that some ppl might keep something worth protecting on their PC, but a regular Joe...please... what... I'm gonna steel his porn collection . The only thing you might be worried about is a hacker storring some questionable stuff on your hard drive, but then again... idf a half decent hacker decides to that all that software won't stop him, you basically would constantly monitor all that software.

    Take care...
    sorry for my ramblings I guess I had something on my mind. Got some more But I'll spare you... I'll go "vent" elswhere.

    Be good now...

    But it is relevant. I dual boot Win 7 and Win 8 using swappable boot drives. My data drives are a single sata drive D: and a RAID drive, E:. I shutdown between OS boots. When I have been using Win 8, and switch to Win 7, Win 7 runs chkdsk on the data drives. Same the other way around. They do not see the NTFS volumes exactly the same way, and jigger them enough to cause the other OS to want to do the chkdsk. Usually seems like minor corrections. I have not had file corruptions. I would really like to know the difference in the NTFS versions that cause this.

    Honestly, not sure, Willy. I dual-boot 7 & 8 & go back n forth w/ no issues, @ all. Never had either run an automatic disc scan. And either will/does see all my drives & can access anything on any drive from or whilst in either. And w/out any corruption anywhere, @ anytime, no matter which OS being used.

    Sorry, mate.

    Cheers,
