External hard drive not recognized in Disk Management

I am having a Simple Tech Pininfarnia 320 GB external hard drive, previously it was working fine but as long as I have inserted it into another PC I have got my external hard drive not recognized in disk management. Whenever I plugged it into my PC it tried to install the drivers but all the time it failed. At the end it shows a message that 'Re-installing the driver might fix the problem'. So what should I be doing?

Well your PC is telling you that you are having problem with USB driver, so go to Device Manager and check for the yellow warning signs. Anyhow under Universal Serial Bus Controllers you will find USB Mass Storage Devices driver, make a right-click on that and uninstall it and then restart the PC. Now the Windows should re-install it automatically, if not then go to motherboard manufacturer's website and download it from there

There could also be other possibilities like, data loss or hard drive might get failed or circuitry in the enclosure has created an error. So in this case you should go for USB drive recovery.

Anyway, remove the drive from the enclosure and connect it with the internal connections of the PC. Or else you can get a USB Hard Drive Adapter from any computer accessories store (online or physically), afterwards plug it in any USB connection of a computer and see whether you can access your hard drive or not.

Thanks for your help. I was able to successfully restore many critical files from a corrupted hard disk. Your product saved me a great deal of time and trouble. Thank Your Very Much!

I wanted to extend my ultimate gratitude and thanks to you and your team. Not only did your company recover the data quickly and at half the price of other companies, everything was recovered and our office is back on track after the NAS failure. I really appreciate a company doing its business so well as Disk Doctors did; and will definitely sing your praises for all to hear. Excellent customer service all around. Thank you again!

Many special thanks for your support in getting my drive issues handled. I am able to access all the files that were recovered. You guys are great!

I thought I was missing a folder until I realized I was searching under the wrong folder name.
I am happy! We are good and all is well!

Thank you.

What do you do when a power surge destroys your hard drive and you loose hundreds of hours of work, irreplaceable images, and your ability to complete jobs for clients with looming deadlines? My first instinct was to cry, then scream. My IT manager tried and failed to recover my data and recommended that I try a disaster recovery service. We went on line and called several companies, and when we reached the Disk Doctors, we knew we had found a company that could help us. I delivered my toasted hard drive to their Vancouver location late in the afternoon and by 6:30 am the following morning a representative had emailed me with a reassuring message and time line for the work. The following Friday I received one of the happiest calls of my life. My data had been completely recovered. I cried and screamed again, this time with joy! Over the last two days I have been thrilled, delighted, relieved, overjoyed and reassured by the fact that ALL MY DATA is once again accessible. Disk Doctors are now on my top-persons list and I am telling all of my colleagues about their services!!!

Thank you!

My hard drive crashed leaving me without my critical financial information and research that is crucial to my business. After checking various vendors on the Internet, I chose Disk Doctor Labs because of their level of service, and they far exceeded my expectations. Aziz Mirza, the manager of Disk Doctor Labs in Norcross, GA, personally took charge of my account, quickly fixed the problems and returned my restored files within a week on a hard drive that I could return for an account credit. Throughout the process, Disk Doctor Labs kept me informed, responded quickly to my calls and delivered my lost files quickly, efficiently and at an extremely fair price. I recommend them unequivocally.

Thank you!
