How to Fix error 1117 Error – Keep getting i/o error 1117 while trying the file operations

Windows I/O Error 1117 occurs when copying large files to external hard drives. Solution involves checking disk space, file system health, and using third-party tools for recovery.

Quick Answer: Check disk space and ensure the file system is healthy; consider using a third-party tool like Recuva or EaseUS Data Recovery Wizard for recovery.

IO Error 1117 is a common issue that occurs when trying to perform file operations on Windows. This error typically occurs due to the hard drive being unable to read or write data at certain speeds, often caused by hardware failures, disk errors, or insufficient resources. It can be frustrating for users who are trying to copy large files, like 50 GB, to external hard drives.

The problem of IO Error 1117 while copying a huge file can be particularly vexing, especially when you've tried various methods such as compressing the file or splitting it using HJSplit. However, don't worry; we're here to help you troubleshoot and potentially recover your file.

⚠️ Common Causes

  • One main reason for IO Error 1117 is a hardware failure or disk error on the external hard drive. This could be due to physical damage, overheating, or a failing hard drive mechanism. If this is the case, it may not be possible to recover the file without replacing the faulty hard drive.
  • Another alternative cause of IO Error 1117 is insufficient resources on your system. If your computer's RAM, CPU, or disk space are not sufficient for the operation, you may experience this error. In such cases, closing other resource-intensive programs and ensuring your system has enough resources can help resolve the issue.

🛠️ Step-by-Step Verified Fixes

Method to recover file using disk check

  1. Step 1: Firstly, open Command Prompt as an administrator and type 'chkdsk C:' (assuming the external hard drive is connected to drive C). Press Enter to execute the command. If prompted, confirm that you want to schedule a disk check for the next time Windows starts.
  2. Step 2: Next, restart your computer and let Windows perform the scheduled disk check. This may take some time depending on the size of the hard drive. Once completed, try copying the file again to see if the error persists.
  3. Step 3: If the issue still occurs after performing the disk check, it's likely that there is a hardware failure or other underlying problem with the external hard drive. In such cases, you may need to replace the faulty hard drive and reinstall your files from a backup.

Method to recover file using third-party data recovery software

  1. Step 1: You can also try using third-party data recovery software like Recuva, EaseUS Data Recovery Wizard, or Disk Drill. These programs can scan your external hard drive for recoverable files and help you copy them back.
  2. Step 2: Download the chosen software and follow its instructions to connect your external hard drive. The software will then scan the drive for recoverable files and provide you with options to select and copy the files back to a safe location.

✨ Wrapping Up

In summary, IO Error 1117 can be frustrating when trying to copy large files to external hard drives. To troubleshoot this issue, first check if there are any hardware failures or disk errors on your external hard drive. If that's not the case, try using disk checks or third-party data recovery software to recover your file.
