Case 1. Cannot Open External Hard Drive
Usually, even an external hard drive is correctly connected to a computer system, and well recognized. It cannot open.
We collected the most frequently occurred errors that would go with the not opening issue and tested out corresponding solutions. The common errors are:
- The disk in drive X: is not formatted. Do you want to format it now?
- You need to format the disk in drive X: before you can use it.
- The drive X: is not accessible. Access is denied.
- Drive X: is not accessible. The file or directory is corrupted and unreadable.
- Drive X: show as xxGB RAW in Disk Management, cannot open it as normal.
Besides those prompt errors, some reasons for a connected hard disk cannot open issue are vaguely known to us, like virus infection or system configuration, and you need to try many approaches to examine, presume and finally work it out.
Take one more step before proceeding with the troubleshooting. Do you have important data waiting for recovery? To retrieve files from an inaccessible HDD, external HDD, USB flash drive or a memory card, EaseUS Data Recovery Wizard is what you're going to use.
How to Recover Data When External Hard Drive Can't Open
Whenever you're facing an inaccessible, unreadable or not opening hard disk drive, data recovery is the priority thing. You can evaluate the EaseUS hard disk data recovery software's capability, speed, and efficiency by installing its demo version placed on the page before purchase.

Fix 1. Format the external hard drive

Step 1. Press Windows + R keys to bring up the Run box, type diskmgmt.msc and hit Enter.
Step 2. In Windows Disk Management, you can check the current status of the external drive. If it's shown as RAW or unallocated, right-click on the drive and choose Format...
Step 3. Choose a file system like NTFS and click OK.
For a better understanding, this method is helpful in all of the following three cases:
Case 1. The External Hard Drive Won't Open and Cannot Run chkdsk
"My 500 GB external hard drive appears on my computer but won't open when I tried to access it. Then I tried chkdsk to check for errors, but it didn't work. Is there any fix?"
Case 2. The External Hard Drive Detected but Won't Read or Show up in My Computer
"My 80GB USB Hard Drive recently stopped showing up in the 'My Computer' folder for an unknown reason, how do I open it and access my data?"
Case 3. Can't Open My External Hard Disk, It's Saying to Format It
"I can't open my external hard drive. It says I have to format it. In the computer, it just shows Local Disk K, but there is no storage reading."
Fix 2. Fix I/O Error on the linked page
When your hard drive is recognized but cannot be opened due to the disk not being accessible with "The request could not be performed because of an I/O device error" message, it can be fixed by running CHKDSK or changing the transfer mode for the drive in IDE Channel Properties.
For a detailed guide, please refer to how to fix I/O device error on an external hard drive.
Fix 3. Request Admin privileges
If you don't have Admin privileges of accessing to your external hard drive, it won't open and usually shows this error message "Drive is not accessible. Access is denied". To fix the issue, you take ownership to get the permissions. To do it:
Step 1. Right-click on the inaccessible hard drive, select Properties.
Step 2. Go to the Security tab, switch to Advanced, then click the Edit button. On the Owner tab, modify the ownership of the specified account.
Case 2. Cannot Open Files on External Hard Drive
If we discuss further the topic of not being able to open an external hard drive, you will find that the problem becoming more serious. In fact, the other group says that they can open the disk drive as normal, but the files and folders there.
In such a case, you cannot directly use the data recovery software as we introduced in the beginning, it's not guaranteed with success. Good luck, when we have worked on files not opening issue before, and I'm going to post the links here for reference.
Case 1. Open the external hard drive and try to open a folder, saying 'this folder is empty'
Case 2. Try to open a file in Windows but warnings showing up as 'The system cannot find the file specified'.
