The “Parameter is incorrect” message usually appears when you attempt to access, or modify files on local hard drives, USB drives, and external hard drives. The error can also pop up when trying to open a file, or formatting the drive.

It’s tricky to determine what exactly caused the issue. The fault could be with the drive’s connector or port, a corrupt file system, or a faulty drive. Fixing the problem requires some trial and error if you don’t know the exact reason for the error. Here are some ways you can fix the “Parameter is incorrect” issue on your drive.

What Does the Parameter Is Incorrect Error Mean

Windows displays the “Parameter is incorrect” message (error code: 0x80070057), when you try accessing, opening, or modifying the contents of a storage drive. Sometimes, it appears as soon as you connect the drive, or attempt to format it.

The error often affects removable storage drives like USB drives, and external HDDs. On rare occasions, internal storage drives like internal HDDs, and SSDs may also face the parameter incorrect error.

Usually, the error indicates that the file system of the affected drive is damaged. But there are numerous other reasons why this error could appear. We explore all of them in the sections below.


You must attempt data recovery as soon as possible from a drive that displays the “parameter is incorrect” message. In worst-case scenarios, the error could indicate a failing drive or an accumulation of bad sectors. If it’s the latter, you’ll need to format your drive to fix the problem, making data recovery vital.

Why Do You Get Parameter is Incorrect Error on External Hard Drive?

The most common reason behind the parameter is incorrect error on an external hard drive, is a corrupt or damaged file system. A corrupt file system is typically caused by one of the following reasons:

  • ↩️ Improper Ejection: Abruptly removing your external hard drive, without ejecting it from Windows first, can cause logical damage to your drive. This, in turn, can damage the file system of the drive, especially if it was being read or written to.
  • 🔌 Improper Connection: A loose or damaged connector can cause read/write issues on your drive. Additionally, your PC may not detect the external hard drive at all or display a message that the external hard drive’s parameter is incorrect. It’s recommended that you connect your drive to a port that’s directly on the motherboard and try using different cables, if you suspect this is the case.
  • 📛 Physical Damage: Physical damage can cause numerous issues on your external hard drive, including a corrupt file system that subsequently results in the parameter is incorrect error on your drive. Physical damage is best dealt with by experts, because it’s really easy to cause further irreversible damage to the drive if you don’t have the necessary expertise.
  • ⚠️ Unexpected Power Outages: Power outages and surges can damage your PC’s hardware, including the external hard drive. A sudden power cut, while the PC is writing or reading data from the drive, can corrupt its files and the file system. Thus, it’s always recommended you have a UPS or some sort of surge protection to keep your data safe.
  • 🚫 Corrupted File System: A corrupted file system can cause Windows to display the parameter is incorrect issue. There are numerous reasons behind a corrupt system, including virus attacks, improper usage, and physical damage.
  • 🔣 Decimal Symbol Configuration: In some cases, improper decimal symbol (.) configuration, i.e. using some other symbol instead of the dot symbol. This typically happens when you use a regional keyboard configuration.
  • 🔒 BitLocker Encrypted Drive: In rare instances, BitLocker Encryption can cause the parameter is incorrect error on your external hard drive. It’s recommended that you turn off BitLocker. Remember to first recover data from the BitLocker encrypted drive and then attempt to fix it.
  • ❌ File Permissions: Not having the necessary file permissions to read, or modify the files on a drive, can result in the Parameter is incorrect error. In this case, the error triggers as soon as you attempt to read, or write to the drive. To fix this, take ownership of the drive, and ensure you have read/write permissions—you’ll need an administrator account to achieve this.
