“Can’t read from the source file or disk” error message usually occurs when you try to copy files from another device, such as an external hard disk. This article will list out the 7 common reasons and solutions for this issue.
Have you ever encountered the error message “Can’t read from the source file or disk”? In general, it can pops up when you copy files from another storage device, such as an external hard disk or USB flash drive. Without any doubts, this error is considerably annoying. You’ll be worried about the integrity and health of your disk as well as your data. Therefore, here we will expose the 7 top reasons behind this error and offer you the corresponding solutions.
1. Bad Sectors on the Source Disk
First of all, there are great chances that the source disk is suffering some issues, such as bad sectors. In this situation, you can just scan and try to fix the hard disk issues. Windows come preinstalled with a built-in scandisk tool – CHKDSK. Thus, you can run Command prompt as administrator, then type “CHKDSK drive letter: /f” and lastly hit “Enter” key.
2. Windows System Error
In addition, perhaps your Windows operating system is malfunctioning, such as unexpected system conflicts, etc. This can result in such an error too. In this case, most of time, a simply restart is able to help you get rid of this error. Thus, restart your PC right now.
3. Insufficient Power Supply
Sometimes, this error can be brought out by hardware issues, such as insufficient power supply. More specifically, if you’re copying files from an external hard disk, you need to ensure it is supplied with enough power. It can lack power especially if it’s connected to a USB hub. In this case, you should leave no stones unturned to offer much more power supply to the hard disk.
4. Loosened connection
Moreover, another common reason is the misconnection between the hard disk and the computer. In general, it refers to the loosened cables. So, you should test the cables. Plug out and re-plug in the cables to see if it make any effects.
5. File Size Limit
It’s very possible that the files that you are copying are too large. There are some hard disks or USB flash drives that are formatted with FAT32 file system, which only supports at most 4 GB individual files. So, you will surely fail to copy the files whose size exceeds the 4 GB. In this case, you can firstly convert the file system to NTFS.
6. Unsupported File Name
Often, unsupported file name is the real culprit. If the file name can’t be identified by Windows, this error will happen as well. For instance, you are trying to copy the files with special file names originally from Mac system. The file name may be incompatible with Windows. In this scenario, what you can do is to rename the files and see if the error will go away.
7. Source File Corruption
Moreover, provided that the files being copied are compromised, you will also get the error message as well. In this scenario, perhaps the most urgent action is to repair the damaged file. You can recur to any third party data recovery tool, such as DataNumen Outlook Repair for repairing corrupt PST. But you should never readily trust in the tools from unknown sources.
