How to Fix The Parameter is Incorrect Error

Did you get "The parameter is incorrect" error message and cannot access your external hard drive, USB drive or SD memory card? How can you fix the error without data lossing? Here are some useful instructions that can help you to fix the issue and recover your missing data.
Sometimes, when we tried to access files which stored on the hard drive, the warning message "I: is not accessible, the parameter is incorrect" appeared. Why?
 

• USB Port problem – the USB is a link between a computer and an external hard drive and once it is not functional, the hard drive might be damaged.
• Improper removal of the hard drive – unplugging the hard drive from the computer directly damages the hard drive hence the cause of the error above.
• Bad sectors on the external hard drive – one bad sector on an external hard drive might make the entire partition inaccessible. These bad sectors might damage the whole drive.
• File system corruption –In computer, a file system is used to control how data is stored and retrieved. Once file system goes wrong, you may fail to access drive and receive some errors like "…the parameter is incorrect", "Data error (cyclic redundancy check)…", "Windows is unable to complete the format", etc.
