Windows 7: External Hard Drive Not Detected

Not yet. Will revert as soon as I check the hard drive on another machine. On the face of it, everything looks Ok with the drive....I didn't touch it since the last time it worked. But will check again to make sure.

Hi again, Marsmimar.......checked the External Seagate 320 GB Sata hard drive (actually it was an internal drive in my laptop, which I changed to external after putting it in a Case) on two different desktop computers, and they also failed to detect it. But the LED Light on the drive was still turned ON, which means it is receiving power. So does this mean that the problem is with the drive? So what to do now to get my drive to work?

I think I'd try a different enclosure/casing. (I've seen them for about $10.)

Newegg.com - 2.5 enclosure

If that doesn't fix the problem it could very well be a drive problem. Can you put the drive back into the laptop (or a laptop) to see if it will be recognized that way?

Looks like we're finally making some progress. The drive is Seagate Momentus 7200.4 320GB Firmware 0004SDM1. I opened the casing (just the top cover), did some replugging and tried to connect it to my laptop (with the casing top cover open). Voila! The laptop recognized the drive and installed the necessary drivers automatically. But now the external hard disc is showing as "Removable Disk (E". But it is not showing the used capacity or free capacity at all. On double-clicking the drive, it does not open but shows a message, "please insert a disk into Removable Disk (E".......now what does this mean?

When I right-click on "Removable Disk (E" to see Properties....it shows used space as 0 bytes, free space as 0 bytes and capacity as 0 bytes. In Properties, when I choose Hardware option, it shows up as a "Generic External USB Device" and not by name of Seagate. My other (internal Hard drive) shows up with its brand name, Toshiba.

Now what to do to see the contents of my Seagate Hard Drive?

Also, when I go to Tools, after Properties....there is an option for checking the drive for errors with a Windows button, "CHECK NOW".....But when I click on that button, a message shows up saying "The disk check could not be performed because Windows can't access the disk".

Now that's what the problem is....Windows can't access the disk! So how to make Windows access the disk?

Go into Disk Managment again and see if it's detecting the repaired drive. If it is, right click on the drive partition and select Change Drive Letter and Paths. Change the drive letter to maybe X, or Z (something that isn't already being used by another drive.) See if that allows you to see the contents and allows Windows to access the disk.

Changed the name to K: nothing happened, still can't open. The disk Management page shows the disc as with "no media". So what next?

Everything you've done up to this point keeps leading me to believe there's some kind of problem with the drive itself.

Quote:
The error No Media indicates that the hard disk could have gone bad. I suggest that you check if the hard disk is detected on a different Windows 7 computer or a Windows XP computer.

If it is not detected, I suggest that you contact the Manufacturer as it could be a hardware issue.

Thanks,

Please forgive me if we already talked about using Seatools (a diagnostic program from Seagate that might shed some light on this.) My one remaining brain cell sometimes loses track of where it's been and where it's going.

Your brain cells are working fine, Marsmimar. Using Seatools now was the next logical thing to do. I ran the Seatools utility and the disc is showing up as "Generic External" with serial number as USB 1394. All the "Basic Tests" in the menu options of Seatools were UNAVAILABLE for this drive except the Short & Long Generic Tests. After running the Short Generic Test, I get the message "Short Generic - Fail". And when I run the Long Generic Test, it flashes like more than 200 errors, and then finally says "Long Generic - Fail". I go to the "Advanced Test" options and only the third and final option of "USB Erase Tracks" is available. I try both the Basic & Full Disk erase options in this and I get the result: "USB Erase Boot Sectors - Fail" & "USB Full Disc Erase-Fail".

So what I can understand from all this is that even Seatools is not able to access the data on my Seagate Hard disk. Now what could be the reason & and how to make the data visible???

Could it be the fault of the Casing again? Am I likely to see the data on my disk after putting it inside a New Case?
