Azure Storage Explorer Issue

Question

Getting error when trying to download an unattached disk from Azure Storage Explorer.
Error: AzCopy failed to complete the transfer. AzCopy error message: UnexpectedQuit

In total there are 4 disks that got created from backup and this is happening with only two of the disks. Both are approx. 8TB each. Surprisingly the download of other 2 disks which are 4 TB and 1 TB in size is working fine without any issues. All recovered disks have same properties, in same Resource Group.

Hi Ash,
Welcome to Microsoft Q&A Forum, Thank you for posting your query here!,
When you're downloading two of the four created disks from the backup. The error message you received indicates that AzCopy could not complete the transfer due to an unexpected stop. This can be caused by several factors, such as network connectivity issues or insufficient disk space on your local machine.

Since you said the download works fine on the other two disks, smaller in size, it could be that the problem is related to the size of the disk The two disks causing the problem are larger in size than the others, this is possible causing problems on your network or local equipment.

Based on your scenario there are few possible causes:

· Check your network connection: Make sure your network connection is stable and there are no issues with your internet service provider. You can try downloading the disk again at a later time to see if the problem persists.

· Check your local disk space: Make sure you have enough disk space on your local machine to accommodate the size of the disks you are trying to download. If your local disk is full, this can cause AzCopy to fail.

· Examine the AzCopy logs: You can examine the AzCopy logs for any error messages that may provide more information about the problem. The logs must be in the same directory as the AzCopy executable

· Try downloading the disk using another tool such as Azure CLI or PowerShell. This will help you determine if the problem is Azure Storage Explorer specific or a general issue.

· If the issue persists, you can try splitting the disks into smaller chunks and downloading them separately. This will help you determine if the size of the disks is causing the issue.
