Windows 7: External Hard disk Iomega 2 Tb recognized by pc but can't be formatted

The USB enclosure is responsible of translating stuff from SATA (the hard drive's ports) to USB, it has a circuit board and a controller. It's not just a metal case with screws, it has active components.

They can and do fail. And when that happens, the USB connection to the HDD can be flaky and unstable like in your case (sometimes they do exactly like your issues). "failure" does not always mean "does not power up at all", but also "powers up but malfunctions".

Only if you connect the hdd to a PC without using the usb enclosure, you can see if it's not an enclosure problem.
You cannot say that it isn't that before trying.

alright guys here's a little update

i checked the disk with seagate and every test marked it as GOOD.

now here's the deal: my pc after that can't find it ANYWHERE.
this hdd doesn't just exist anymore and can't be found no matter what and weith any program.
the only way i have to noticed it has been connected to my pc is that as soon as i plug its usb cable in, windows makes that common sound/jingle.

however it's like i haven't even connected it.

cant be found anymore no matter what on disk managment either...

Important Data missing!

Did you check it with the HDD inside the enclosure or the bare HDD hooked up as a second drive on a desktop PC?

There are only two tests you should perform. One is the short test and another long test.

If the Short test passes, there is no need to run the long test. No harm if you do run it. Only thing is it will take a long time.

When you say all tests, what other tests do you mean?

i mean both short and long test

both gave the same good result

i don't have anyone who as of right now would let me put my faulty hdd on their pc.
i asked around but not a snigle frined of mine would agree and let me do it.
so of course, those tests were run with the hdd inside its enclosure

OK, it is now certain that the interface electronics in the enclosure has gone bad. Earlier it was partially bad, not allowing to read/write the HDD. Now I think it is completely dead. Good riddance. This peculiar problem you had faced is the first of a kind I have seen.

The Seagate HDD inside has passed the test. I would think the data is still there safe.

You may buy a good brand external case , put this HDD inside and use. Handle the bare HDD carefully not touching the electronics board in it.( Leave it inside the external case till you decide what you want to do with it.)

With this, I think you can close this thread as solved unless you have any further queries.

ok

But keep in mind that as soon as i connect it to my pc, it's immediately recognized by windows which makes that sound/juingle of "new hardware plugged in".

don't you think it means something?

It means that some external device has been connected. That part of the interface circuit is still functional that gives that info to Windows. Earlier Windows could even get what it was, how much capacity etc., and only that part that was routing the read/write operation was faulty. Now even that is gone. That is all to that.

From a practical point of view, if Windows cannot recognise that an external drive has been connected, your external is dead. Taking only two major blocks - the interface card and the HDD we have determined that the interface card is faulty.(Some electronic blocks in the interface card itself may still be functional but that does not help)
