Bad Sectors

Sectors Gone Bad

Does your computer no longer recognize your hard drive or can no longer access any of your data? It is possible that there is an issue with the internal components called sectors within the hard drive identifying them as “bad sectors”. Simply put, a bad sector in a hard drive is a cluster of storage space on the platter of the hard drive that appears to be defective, and the data within that cluster (AKA a “sector”) cannot be read or written properly.


Causes for Bad Sectors

There are two causes for bad sectors on the hard drive. The first is due to physical damage within the hard drive itself, called a physical or a hard bad sector. Scratches on the platter can lead to more hard bad sectors, which in turn leads to data written on these sectors to become unrecognizable by your computer. Moreover, the second cause for a bad sector is a logical, or a soft bad sector created by the operating system or a firmware corruption on the hard drive.

Do you think your hard drive has bad sectors due to physical mishandling of the drive? Also, do you think the firmware update didn’t download properly? Then it is time to bring in your hard drive to Five Star Data Recovery. In addition, you will receive a FREE diagnosis and a FREE price quote for data recovery services.

Fantastic experience! From start to finish, Vahan and his team were amazing… incredibly knowledgeable, kind, comforting, and easy to talk to. And…. even better, they were able to save most of my corrupted files. Highly recommended!

Vahan and his team were very communicative and helpful. I had an external hard drive that crashed. It was a 2TB Seagate. He was able to get all my files back. I would highly recommend to anyone looking for data recovery to come to 5 stars. They’re very friendly and respectful. They will answer all your questions.

Excellent, courteous, and professional staff. From the front office staff to the engineers they’re all pros! I was told by other places that my data probably wouldn’t be able to be retrieved. And their quotes were ridiculously expensive. One place wanted to charge more than twice the cost of my Mac. Five Star were quite different: Pleasant, never pushy, reasonable prices, and excellent service. They were able to recover all my data and had it ready in less than a day! Highly recommend 5 Star. BTW Ellen is super cool!

Losing data is never a fun experience. However Five Star Data Recovery makes you not feel as bad for dropping a hard drive, or losing any files. The facility is neat and clean, and they have a certified clean room for all the repairs which automatically makes them better than your average. The ladies at the front desk were inviting & sweet. The communication throughout the process was transparent and clear. My hard drive was fixed, recovered, and transferred to a new drive in only a few days, and at a competing, or even better price than the next. Thank you guys!
