Hi guys, I have a Dell OEM 7200.11 750G drive and it went undetected. I am following the procedure to reset the hard drive. After I entered U to spin up, it is stuck at the command and doesn't go back to F3 2> even for a long time. Then I pressed enter, it give me the F3 T>, and I went to level 2 to spin up again, it says spin up complete elapsed time 0.000 secs. So I went on executed N1, then m0,2,2,0,0,0,0,22. The last command didn't go back to F3 T> as well for 10 mins or so. I powered off and installed to my computer, it is now detected by BIOS but capacity is unknown. What should I do now? Any help will be appreciated! Thanks in advance!
