So this happened a while back and I am finally have time to do something about it. So i'll break down the issue.

I run win7 x86, pc works fine. I use an external drive on the NexStar CX. My gf's laptop has the same external unit but on XP. Worked no problem then one day it just flopped. I took my drive over a few days later because her laptop has limited memory, and a few hours later it burned my HDD.
Any ideas what may have caused this, i keep hearing dead drive, but if it happened twice I think its just coincidence and that maybe the boot for the drives no longer work.

Any help or suggestions would be greatly appreciated.

PS it does show in the Bios though

1) Is it a 3.5 inch hard drive enclosure which uses and external power supply or is it a 2.5 inch drive which just uses USB power?
2) If you can open up the drives and install them into a PC that might determine if its just the USB Adapter in the case that is the problem. If it is you can just buy new External Cases. I perfer the Rosewill cases. They are good and cheap in price.

It may still show in BIOS as a USB drive/eSata drive but once it loads windows there can be issues with the hardware and windows can't read what it is. If you go to device manager it might be under the USB sections as an Unknown Device if its malfunctioning. do you get the USB noise at all when you connected it to the PC?

I went out and got a sata3 cable and plugged it to PC directly. It reads the drive, but now tells me the drive has an I/O error and asks me to format. I've tried recuva and same thing.

Yea an I/O error isn't good. Its almost always bad hardware. Can you download the Crystal disk Info in my signature and install it and run it while the hard drive is connected. See if it list it and if it does can you give me a print screen of what it says?

I tried a few different things, such as Recuva, EaseUS and a few more. A friend recommended Fedora Live but I couldnt get that to work.
This mean my drive is just junk now?

Pretty much. The only other thing you could do if you really needed to get data off of it is to find the same exact hard drive. Exact same model number. Then you can swap the board on the bottom of it and try that The I/O error more than likely caused by a bad board.

if that doesn't work then its a problem with the heads which i wouldn't even dare trying. If its not coming up at all its more than likely the board.

the drive is seen in disk management and bios, but whenever its hooked up it asks me to format it.
As in the photo, its there, just no information.

if there isn't anything you need on it try to format it. If there is you may need to get a recovery software to get the data off IF the drive is actually working. If its not (and just because the BIOS and Disk management doesn't mean it does work) formatting or using recovery software won't help.
