How Do I Fix The Parameter Is Incorrect
Now, before fixing the error "Drive is not accessible. The parameter is incorrect", I want to introduce what caused this to happen at first. Knowing the exact reason, we can solve the problem with ease.
Cause of the error message "Drive is not accessible. The parameter is incorrect"
In general, various reasons can cause this error, including:
Pull out removable devices in an improper way: Some users including me may directly pull out our USB drive or other storage devices without ejecting. Force removal of drive may do harm to or even destroy boot records of partition, thus we cannot access its data and receive the "…parameter is incorrect" error.
USB port problem: The USB port is the bridge which connects the removable drive like USB flash drive to computer, once it gets problem then the removable drive may get damaged at the same time. Thus, this drive cannot be opened and reports some errors like "…is not accessible. The parameter is incorrect".
Bad sectors on the hard drive: As we all know, even one bad sector can make entire hard drive inaccessible.
Power failure for powered hard drive: Power failure also is one of the reasons which cause the hard drive inaccessible or unreadable.
Virus attack: Virus infection or malware attack can also cause "the parameter is incorrect" error.
File system goes wrong, such as DBR, MFT, FAT: In many cases, the error "Drive is not accessible. The parameter is incorrect" is caused by file system corruption.
In computing, 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 was unable to complete the format", etc.
After knowing the reasons, let's talk about how to fix the parameter is incorrect.
