Failed to mount /dev/sda2 input/output error



  • Hi all,

    I have a real mystery here. I’m trying to reimage a variety of netbooks with a Fog image of Windows 7 Enterprise, etc… Some are HP Minis, some are various Acer, and some are Asus EEEpcs. The Asus EEEpcs are giving me grief.

    In general, all the netbooks start PXEboot and begin imaging, although the EEEpcs sometimes need a couple of tries before they get a DHCP lease. But on the EEEpcs only, imaging stops at random points. 5%, 8%, 55%. Eventually, one EEEpc took the image after 4 attempts.

    The message I get is:
    $MFTMirr does not match $MFT (record 0).

    Again, the other netbooks take the same image no problem, so I don’t think it’s an image problem. But I’m not sure what’s up. I’ve tried a different switch. I don’t know why it’d work after several attempts. My gut feeling is that the netbooks might have flaky NICs…but…all of them? I could look at kernel updates but I’d think that be more of a problem if the netbooks wouldn’t even PXEboot. That being said, PXEbooting is a bit of an issue. I’ve seen similar posts on the forum but they seem to be failing for all, whereas this is only failing on these EEEpcs, and only some of the time. ???

    Any ideas?
    Thanks in advance,
