I don't know if MS sent a patch Tuesday or not, but this happened on the first reboot since then. Win 7 Home - Cannot access the C: drive. When I choose repair option and open a cmd window it shows the drive as X: I can change to D: (cddrive) but when I try to access C: it says "There is not enough space on the disk." No other "repair my PC" options worked either. The harddrive shows in the bios. I can start (and then cancel) a new install and it shows the drive. Chkdsk runs clean, but not sure it is checking the C: drive when run from the X: promt even though I typed chkdsk C: /f I have tried to run SFC, but to get to the CMD window I have to use the repair option and it sets up a flag I guess that won't let SFC run w/o reboot which just sends me in a loop. I do not have a restore disk or sys image. (not my PC... my sons) Any suggestions are welcome.
