    Hardware could be to blame for your problems. My philosophy is everything is suspect until the solution is found. From your explanation, I am reasonably sure Drive M has a problem. It can have nothing to do with bad sectors. There are quite a few factors that go into making a drive work right. Try the same operations without drive M connected at all and see if you get the same results.

    Hi essenbe,
    sorry for the delay, work has taken over a bit! But, I have just had a corrupt file on my the laptop I am working on while I deal with the orignal problem on the desktop. Whilst it may just one of those things, I am not somewhat concerned I may have picked up something unpleasant, virus or malware.
    What is the best virus checker that runs from a bootable CD?
    Just want to make sure i have nothing on my laptop or desktop :)

    thank you for your help

    You can run a complete scan with your current Anti Virus then run these online scanners:

    Scan with Kaspersky TDSSKiller:
    Anti-rootkit utility TDSSKiller
    Anti-rootkit utility TDSSKiller
    ESET online scanner:
    Free Virus Scan | Online Virus Scanner from ESET
    Free Online Virus Scanner | ESET

    Hi essenbe, thank you for the links. Ran them and came up clean. Then ran chkdisk again on the raid and it came up with more bad clusters. I am guessing the raid drives are at the end of their life. Or can bad clusters be caused by something else other than drive failure? For example a faulty motherboard or cables?
    Also ran chkdisk on the new evo ssd (c:) and there was a repair required on the journal, I don't have the exact message, but is this normal for a new drive or something I should be thinking about returning?

    As far as the SSD, the Journal entries is nothing I would be concerned about. It does not seem to me, that it is a defect in the drive, just in the files. As far as the bad clusters on the raid drives, I would plan to replace them, if it were me. As I understand it, a surface scan checks the surface of the disk. If it finds sectors where it can't read or write to, it notifies the controller not to use those sectors. But many times, once bad sections of a disk is found, they grow larger until the drives fail.

    Hi essenbe,

    apologies for the lateness in reply.

    I had no faith in the hardware and could not take the risk in working on it. Eventually bit the bullet, replaced the riad drives and formatted everything and started from scratch.

    After about 4 weeks, nothing seems to have gone wrong and I have my fingers crossed it will stay that way for a while :)

    thank you for all your help and support.

    sorry, missed the mark thread as solved. Is there anything else I need to do? Is there a points system to give you points or something like that? Or will the happy vibes winging its way to you from a wet west coast Scotland location be ok? :)

    Yes, that's fine. I'll take the happy vibes, I need them. No problem about the mark solved. The scale icon in the top right is how to give someone a Rep. But, I already have more than I deserve. Thanks for the thought though, but it may come in handy for other threads in this forum. I hope you will stick around. There is much to be learned here.
