How to eliminate potential problems on USB Powered Drives and keep them healthy.

[Mordahin]

HI! I have WD My Passport 250GB. And Win7 install Initio Default Controller. I cant see my WD. What happening?

There is a problem with the drive contact customer service. Either the firmware is corrupt or the bridge board is damaged.

So I followed the insturctions on above on my 1tb drive that was basically shutting down all the time. I ran HD Tune and  HDD Regenerator 2011 trial  with the prescan that basically said  all of my sectors were bad. I went to purchase the full version and now my computer/s won't recognize the drive at all! I have tried cleaning the usb ports, new cables etc and I hear and see the drive turn on but it won't show up on my computer. Any suggestions at this point?

Before I did the above my computer would at least boot the drive and I had access to my files and now nothing.

Thanks

Can you see the drive, or the USB enclosure, in Device Manager? Disk Management?

How does Microsoft's UVCView utility see the external drive?

I am experiencing the same problem as you guys. This is so frustrating. Read Mabkay solutions but with no success. 

I have A My Book 500GB external HDD which was working fine for the past 4 years and approx 2 months ago started having trouble connecting to the lap top. It sometimes took hours to be recognised and now it won't get recognised at all.

My HDD has its own power cord (connected directly to a wall socket) and the light works as well.

I have tried connecting the HDD to 2 different lap tops (Vista, Win7), different USB sockets and also tried 2 different USB cords. Nothing seems to help.

I cant see the drive on Device Manager (Disk Drives, Other Devices) and  the HDD Regenerator couldnt provide much help either.

I am helpless. This is my backup drive and all my old data is stored on it. (The source data is long gone...)

I'd truly appreciate your help

I have a WD My Passport 1tb external hard drive 0730.  It will not work with my notebook.  I have the impression from schematics I have just read that this drive probably needs one or two amps rather than the nominal half amp usb maximum to function.  That is probably why it is recognized in all my desktop computers but not in my Acer Aspire 7551G notebook, which is what I bought it for.  I can see it in disk management, etc. but because it is not recognized I have problems identifying and/or restoring images created in backups. Nova reports, "I have found a disk that I cannot work with.  Will a powered usb hub of, say, 1 amp or 2 amps, enable windows to see it on my notebook or do I have to buy one of those two usb y adapters that will take away all my ports?

Dear Community , 

I am also facing a similar problem with 70% bad sectors in my 500 gB WD passport ..

i treid all the steps mentioned by MABKAY and started regenerating sectors. But unfortunately the process of regeneration gets stucked in between after regenerating few sectors and i get a message to restart my system and start the HDD regenerator again. so i have to start Regeneration process several times and for Sectors almost close to 0.97 Billion its a bit complex and tiresome.

i will try to post the screen shot for error in case if its needed.  

would love to look furthur in this .. please provide me guidance to overcome the same.

thank you everyone for all the ncecessary help and feedbacks. 

thanks and regards,

Ashish
