Nope. I don't use TM, but pointed you to the best available guide. I suggest that you visit an Apple repair station.27" i7 iMac SL, Lion, OS X Mountain Lion (10.8.5), G4 450 MP w/Leopard, 9.2.2

Have you looked in Disk Utility?
Have you tried all connection ports/?
Have you tried another connection wire?
Have you swapped it into another enclosure?
Have you connected it to another Mac?
Will other HDDs be recognized by your iMac?

Hi OGELTHORPE The problem is not with the external HDD but with the inmate, when I was doing time machine back to the mac froze and I had to turn it on again and I recognized more internal hard drive of the mac but detects the external HDD without problems. the problem is that the hard drive in the disk utility says 0 kb of capacity

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
