Put Xcopy of Windows onto Iomega external harddrive and did not update. That harddrive seems to crash my pc when I now try to attach it. Is there any software (it did not come with software) where I can remove xcopyf:\windows when that hard drive is not even recognized. Data recovery is very expensive and I've got photos that I did not save on c: drive. Also error meesage on chkdsk: F parameter is not set up. I do have a small computer repairshop nearby me. Do you think they can help. No I did not format.
