Summary. It may be due to insufficient capacity of the portable hard disk, or due to the file system incompatibility of the portable hard disk, so that computer files cannot be copied to the external hard disk. In addition, it may also be due to the slow read and write speed of the portable hard disk, resulting in file copying failure.

If this happens, you can try replacing the external hard drive, or changing the format of the computer file so that you can copy the file normally.

What happens when computer files can't be copied to a portable hard drive?

It may be due to insufficient capacity of the portable hard disk, or due to the file system incompatibility of the portable hard disk, so that computer files cannot be copied to the external hard disk. In addition, it may also be due to the slow read and write speed of the portable hard disk, resulting in file copying failure. If this happens, you can try replacing the external hard drive, or changing the format of the computer file so that you can copy the file normally.

If you are unable to copy computer files to a portable hard drive, it may be due to several reasons:1Insufficient capacity of the portable hard drive:

If the file you want to copy is too large and the capacity of the portable hard drive is insufficient, then you will not be able to copy the file to the external hard drive. 2.The format of the portable hard drive is incorrect:

If the file you want to copy is in NTFS format and the portable hard drive is in FAT32 format, then you will not be able to copy the file to the external hard drive. 3.Portable hard drive failed:

If your portable hard drive fails, you won't be able to copy files to your external hard drive. 4.Computer system malfunction:

If your computer system fails, you won't be able to copy files to your external hard drive. If you are unable to copy computer files to a portable hard drive, it is recommended that you check the capacity and format of the portable hard drive, as well as whether the external hard drive and computer system are faulty, so that the problem can be resolved.

The copied file opens as an empty file.

If the copied file opens empty, it may be because the file itself is corrupted or encoded incorrectly, or because the file is infected by a virus, it is recommended that you try using another file opening software to view the file contents, or use antivirus software to scan the file to ensure that the file is safe.

If the file you copied into opens empty, it may be because the copied file is incomplete, or your computer system does not support the format of the file. You can try using a different file format or re-copy a complete file into it. If your computer system does not support the format of the file, you can try using a different file format or use software to convert the file to a different format so that it can be opened properly.

Summary. Here's how:

1 Make sure that the mobile hard drive is not encrypted and write-protected, and cancel it if it does.

2 Reformat the portable hard drive and copy the files.

4 If you don't have the "Security" tab, click on the "Tools" folder option in "Explorer", click "View", find "Use Simple Share", and remove the hook.

What is the reason why the portable hard drive cannot copy files into it.

The scanning time will be relatively slow, wait patiently, the scanning is completed, and the problem of general non-replication will be solved, if the input command prompt permission is not enough, you need to open cmd as an administrator in the input command, you can refer to: Run chkdsk e:f access in cmd is denied, because there are not enough access privileges.

You have to call this utility that runs in elevated mode.

Dear, find <> for you

There are several reasons why computer files cannot be copied to a portable hard disk:1The file size is larger than that of a portable hard drive.

2.The format of the portable hard drive is FAT (32) and cannot accommodate files up to 4GB of storage capacity. 3.

The portable hard drive does not have a partition or the current partition is not compatible with the current system. If you find that the first cause is the problem of the file failure, you can try to use a larger capacity portable hard drive to accommodate the file to be copied. If you find that the second cause is the cause, you should use Disk Management to format the portable hard drive to NTFS format and then copy the files again, which usually solves the problem.

If you find that it is caused by the third reason, you should take the portable hard drive to an Apple computer and use Disk Utility to format it as Exfat, so that the portable hard drive can copy files in both macOSX and Windows systems.

Check to see if your portable hard drive is write-protected.

Some portable hard drives may have them.
