"I get the cannot open volume for direct access error while using chkdsk to scan and repair a damaged memory card. The memory cannot open in Windows File Explorer, and it shows 0 bytes in Properties. Moreover, the memory card always asks to format it before using it. So I try fixing the memory card with chkdsk command. It seems that chkdsk is not working on the memory card. What's your suggestion?"

Chkdsk, short for check disk, is a free utility built inside Windows operating system, and it scans and checks file system for logical and physical errors on either internal or external storage devices. It is usually used with parameters like /f, /r, or /x to fix errors. When a volume is corrupted and inaccessible, the first idea come to your mind might be running chkdsk. However, the chkdsk command may not work as expected in some cases, for example, it may end up with the error "cannot open volume for direct access."

In the rest part of this article, we will discuss why this error take place, how to retrieve data from corrupted volume and how to fix the error via different methods.


Why does direst access say cannot open volume?

The reason behind the problem differs from one to another, and here is a list of possible causes.

  • The drive being repaired is locked or accessed by other applications or services. Chkdsk command needs to gain the privilege of the drive before it can read or write data on the drive, and yet the command usually requires exclusive access of the drive. So, sometimes the chkdsk not working issue is caused by privilege problem.
  • Th volume that cannot open has bad sectors. Bad sectors do not respond to read or write actions, and they can also slow down or even freeze computer.
  • The mount path of the drive has errors. The drive letter of the volume you are trying to repair might be missing, making the drive inaccessible. Try assigning a new drive letter to eliminate the issue.
  • The volume is corrupted. The file system structure of the drive is damaged or corrupted, and the problem cannot be repaired by disk checking.

How to recover data when chkdsk cannot open volume for direct access?

Reminder: If there are very important files in the partition to be repaired, you must first perform data recovery before trying to repair the error. Because any repair operation may cause further damage to the data and reduce the success rate of data recovery.

DiskGenius Professional Edition provides effective solutions to partition recovery and file recovery. The RAW drive recovery or corrupted partition recovery can be done via simple steps quickly, and the recovery applies to various storage devices including hard disk, external hard disk, memory cards, USB flash drive, thumb drive, virtual disk, etc.

To recover data from inaccessible volume, try steps below:

Step 1. Install and launch DiskGenius Professional Edition. Find the corrupted drive from which you want to recover data, right-click on it and choose "Load Current Partition Intelligently".

This feature can quickly load files in the inaccessible drive without scanning it from beginning to end, and files loaded by this feature keep original names. Once your files are found by this feature, then skip to Step 5 to preview files.

It is common to see that this feature does not work as expected, as the drive might be badly damaged, or it was not NTFS file system. In this case, you just need to move to Step 2 to perform a deep scanning.

Method #4: Check and repair bad sectors for the drive

Bad sectors are not readable or usable, resulting in inaccessible volume. We can scan the drive to detect bad sectors with DiskGenius Free Edition. Then use this tool to fix bad sectors and make them usable again.

Note:

  • Repairing bad sectors does not equal to data recovery, and lost files cannot be recovered by way of repairing bad sectors.
  • Not all bad sectors can be repaired by software, for example, hard/physical bad sectors. Whatever the type of bad sectors on your drive, back up or recover data as soon as possible.
  • Close all programs that are using the disk before checking bad sectors.

Step 1. Install and run DiskGenius Free Edition on your computer. Select the drive you want to check bad sectors, and click "Disk" – "Verify Or Repair Bad Sectors".

Note: Do not install the application on the disk you want to scan for bad sectors; if you want to check bad sectors for OS disk, it is suggested to boot to DiskGenius WinPE Edition and then start the bad sector scanning.
