Win 7. Can't see external drive.

Hello,

Recently I've re-installed Win 7 64 on my PC.

My external drive worked just fine, but 3-4 days ago I have noticed that the drive is on (green ring was lit) but when I went to Windows Explorer, there was no letter of the drive visible and I could not access my folders/files stored on that drive.

Some info:

1)      WD drive - link to it's specs
a.      http://support.wdc.com/product/download.asp?groupid=101&lang=en

2)      Under Devices and Printers – it shows as Mass Storage Device icon , looks OK
3)      Under Win Explorer no letter drive visible.
4)      Also it's visible as Drive “A:” under "Disk Management:. It says Disk 1, Removable (A:),  but... it says "No media"
5)      Worked fine 2 weeks, now can't see the drive in Explore, and when saving file, I can't select that drive neither.


Thanks for help!

I assume you haven't an actual Floppy drive A then no?

If not you possibly need to change drive letters that are assigned to the external - right click on the drive under Disk Management and select Change Drive letter - change to G/H or something and see if it reappears...

No, this is new PC, no floppy :-)

I know, I've reassigned letter before, it didn't fix the issue.

It was drive G: before , and it didn't work, so I've change it to the first letter, A:

Ok, can you run this command and post the output thanks...

From command prompt

diskpart
list disk - this will produce an output
list volume - this will produce another output

Post those here so we'll see if the drive is really connected

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

As per screen above, looks connected? But No Media?
Could be that the disk itself went bad?
I've tried to run SpinRite on it, no success.
BTW it's drive F:
I've changed the drive letter per previous suggestion.

Have u tested this drive on another pc?
From the info it appears its gone bad yes
Simple test is to connect to another machine to verify

look if you can open the drive, and connect the disk directly to a sata cable  - to eliminate the USB bridge, cable, and connector

it can also be lacking power, so try it with it's own power, or use the USB connecters in the back (they supply a bit more power) or use a POWRED USB hub like this :

SpinRite actually told me there is a disk error, no other specifics.

Yes, I believe the drive has power. The light (green ring) is lit.
And my PC seams to be connecting, but I can't see the files on it...

Can you check on another machine? If not then as @nobus mentions it may be the enclosure that is faulty

nobusCommented:
i did not say it has no power, i said it could have a lack of power, since usb ports output Max 5V at 0.5A = 2.5 W, and even less on the front ports

so try what i suggested, and don't take anything for granted - just test it !

Yeah, I see.

I plugged this guy into my laptop, and it was not recognized. Zero reaction.

WD, my model, has an external power source AND links with my PC via USB - as per link in my original post.

Right, well the only thing left then is to remove from the enclosure(if you really want the data back)

If its under warranty then you can take it back to where you bought it, not sure what the chances of data recovery are in that case, if its out of warranty(and it was my drive) I'd take it out of the enclosure and connect it directly into a spare SATA port on the pc - do you know how to do this?

"connect it directly into a spare SATA port on the pc - do you know how to do this?"

- nope, I don't

smckeown777Commented:
Ok, well it involves opening the case of the pc, connecting the drive's SATA and power ports to the motherboard..etc...etc...

Or, do you know anyone handy with pc's? Might be safer to get it to them to have a look...

But basically the WD device is simply an internal hard drive 'enclosed' in a case and that case has a USB header which allows you to connect it to a pc - since the drive isn't appearing at all we need to take the USB out of the loop and see if the drive itself is still working...I'll see if I can find a video on youtube to assist...

this can be anything froma bad usb cable, the usb bridge, or the disk
that's why you best connect the disk directly to a sata port
here's how to open it - note that it voids warranty   http://www.youtube.com/watch?v=-_2oMyoTBno
 here a guide for connecting the drive to sata :  http://www.youtube.com/watch?v=kCgFYNLzn18
