Besides, when there's something wrong with the disk, DiskPart will "strike". For instance, "DiskPart has encountered an error" is a frequently seen alert message. The results of the survey show that this error can be caused by a lot of reasons, like parameter is incorrect, access is denied, I/O device error, media is write protected, etc.
Here, in the following content of this article, we'll introduce the main causes for mentioned hard disk error. We'll analyze them briefly and give corresponding solutions to help you recover useful data from the problematic disk with MiniTool Power Data Recovery – a professional data recovery program that is favored by a plenty of computer users.

We will summarize 6 cases that belong to DiskPart has encountered an error. For each case, we'll give our explanation on the causes and corresponding solutions clearly. Please figure out the case that is the same as or similar to yours and then use related ways to try to fix disk error.
Before diving into the specific causes and solutions, we'd like to show you how to recover data from the defective disk. Considering the fact that you may make mistakes during the disk error fix process (which may lead to data overwriting), we strongly advise you to recover important data off the target drive at first.
How to Recover Data from Disk with Error
The first step is definitely getting a suitable license of MiniTool Power Data Recovery. Of course, you can download the free edition to try, but you should know that the free edition has a 1 GB data recovery limit. So please make your decision after analyzing your own situation.
The second step is selecting the most suitable functional module from the main interface shown below (take the free edition as an example).
When running into the problem: DiskPart has encountered an error, you'll probably receive the following error message:
b). access is denied
c). I/O device error
d). data error (cyclic redundancy check)
e). the system cannot find the file specified
f). the device is not ready
All of those messages suggest that your disk is inaccessible, but it does exist. So at this time, you should click on the "Damaged Partition Recovery" module, which is used for deep scanning and recovering data from damaged, RAW or formatted partition.
The third step is selecting the partition you'd like to recover data from and clicking on "Full Scan" button in the lower right corner to search for the lost files.
Well, in the lower left corner of above interface, there exists 2 buttons – "Refresh" and "Settings". The first one allows you to refresh the partition list when the target drive is not showing up; while the latter one is able to help you configure the scanning range to only specified file systems or file types.
The fourth and final step is picking out the needed files found by the data recovery software and clicking on "Save" button to specify a storage path for them.
Please add check marks to the square box in front of the "File Name" column (you can choose to check all files in a found drive or check only some of the files included in it).
If there are too many files displayed in the scanning results, the difficulty of finding certain files will be increasing. However, you don't need to be anxious since the "Find" function and "Filter" function are going to help you locate the needed files accurately by file name, file extension, file size, file creation date and modification date.
Till now, we have shown you all the steps to recover data from not accessible drive; please follow these steps carefully when hard disk error like data error cyclic redundancy check occurs.
