Disc needs to be checked for consistency.

    Over the last few weeks, I have been getting the message "Disc Z needs to be checked for consistency", where "Z" is one of my external drives. At first, I thought that it WAS the named drive, since it was a few years old, and maybe starting to fail. So, since they are not that expensive, I bought another. On occasion, it still gives me the message however (mainly if i add data to it, but not every time on start-up). Therefore, I can only assume that it is the MAIN drive either starting to fail, or a software problem. I have already reformatted the main drive, and it (the message) still returns. So, I let it run it's little disc check, and it usually fixes the problem, until I add more data. It's a random thing. I have done a little research, and some posts say that it is the drive taking too long to empty the cache. Since the "C" drive was reformatted, and the problem returned, I am at a loss. However, now some of my folders are becoming corrupted, and unable to open (unless I send the entire folder to the Recycle bin, and then restore it (weird). Any help or suggestions would be appreciated. :)

    Data corruption on external drives can be caused by not properly disconnecting the drive in windows before unplugging it from the USB port. Do you always do the "safely eject this hardware" thing?

    If you're concerned about your main drive, check the SMART status and (right now) do a surface scan. The surface scan is one of the scandisk options.

    Actually, I never remove them at all (I have had an external drive for over 5 years now). I have always just shut down the machine (using "Shut-down"). The problem started about a month ago, so I don't think that that could be it. The "SMART" status is healthy, and I have run all sorts of hardware diagnostics on it, and it passes all the tests (all 3 drives pass - the main drive, and the 2 external drives).

    I'd ignore it, don't think its a bug but it is one of those annoying things that XP and Vista do time and time again to some external drives. I always get that happening if I leave a USB pen drive connected, every time it wants to check it and no matter how many times I do it always comes up as OK. I was thinking it might be something to do with external FAT and FAT32 drives as on always seems to check those.
