I'm not british or american so my english may be bad.
I've got an external WD Elements 1023 (1 TB). This morning I plugged it into my notebook's usb port and it took several minutes before my pc loaded it. Then Windows 7 told me to format the drive cause it's blank. Same thing on other PCs.
So i have been running testdisk all day. First times it showed me some messages about some mismatches on head's number and something I do not remember. Two or three attempts later (I did not write anything) those messages were gone and now the following stuff is all I can give you. I can't attach log file because it's over 1,700,000 kb

I changed head to 255 and sectors to 63
