was having some problems with some files/folders after 3yo daughter sent the external HDD for a tumble to the hardwood floor. ran chkdsk r/ to fix it. it ran for 2 days and was only 1% complete. seemed to be stuck on one particular jpg for quite a few hours. figured it was frozen so closed dos window. rebooted several times but drive will not come up and cannot restart chkdsk. it says "unable to open drive" (or similar). it does appear in the taskbar as a drive to "safely remove" but can't see/read it otherwise. any thoughts/help would be appreciated.
