“When I connected my external hard drive to the system, I was not able to access it. Rather, an error message popped up saying the disk structure is corrupted and unreadable. I ran Check disk, but it didn’t help, because the disk couldn’t be accessed. I’m worried about my data present on the drive. I need to fix this error message as soon as possible, without losing data.”
Don’t worry, there is a way to fix the error message. “The disk structure is corrupted and unreadable” error is common with external hard drives, memory cards, USB drives, and other storage mediums. This error message indicates that your hard drive file system is corrupted, has turned RAW, or has become inaccessible. So let’s see how to resolve this issue, and also save your data. Follow the steps:
- Bring up the Run dialog box on your Windows system, and type cmd
- Hit Enter to bring up the Command prompt window
- Now type this command: chkdsk e:/r (replace e with the drive letter of the external drive showing error)
- Now hit Enter
This should resolve the issue and now you can check if the error message is fixed. If it still remains, then you can follow the next method.
Recover data from the external drive and reformat it:
If the above method didn’t fix the issue, then the next step is to recover data from the drive and then reformat it. In order to recover data from the inaccessible external hard disk, you can make use of Remo Recover tool. This software will quickly and easily retrieve data from the external drive. Not just that, it also comes handy to recover formatted data from hard disk, external hard drive, flash drive, etc.
Once data is recovered, the next step is to format the drive. You can run diskmgmt.msc to bring up Disk Management window. In the disk map, right-click the partition in which the master file table is corrupt and choose Format. In the next window, enter the file system, volume label, and cluster size. Windows will ask if you really want to go ahead with the format, confirm and proceed.
This method will fix the issue, and you should get back to working with your external hard drive as usual. Suppose you don’t want to format a corrupted drive, and want to fix the issue without the format, then follow this link – which explains how to fix corrupted hard drive without formatting. So there you go, hope this helps.
