Sabrent external hard cannot save file on it

When you connect an USB drive to a Windows machine, or a Mac the drive is shown. On a Windows machine in the explorer with a new drive letter, like D: or E: on a Mac it is on the desktop with a name.
Then you can access it as any other drive. But if you are using program's like Office, you have to tell the software what drive and what folder is the default folder to save your data.

In explorer and on the Mac with finder, you also can move files around to any folder you want. On the internal drive or to the external drive.

Your floppy disk drive may be defective. Also, Some floppy drives are manufactured differently. Your best bet is to find another floppy drive to read your floppy disk. You can try to take it to the nearest computer store and ask them to read it for you. If they can read it at the computer store? The Sabrent drive you received if bad. If they cannot read it the floppy is bad. If the floppy is bad you can try to download free data recovery software to attempt to recover your data, files etc. Good luck

hello,

your hard drive should be recognized by win automatically when you plug in.

That is usually an error code related to the wrong drivers. Go to device manager in windows to see what it says. If there is something on the device list showing an error you need to go here and download the drivers. https://www.sabrent.com/downloads/

Did you format the disk using NTFS? Have you loaded the software that came with the drive? Once the software is loaded it will take you thu the steps to set it up properly

Open the enclosure, plug the IDE cable into the back of the hard drive. Plug the power connector into the back of the hard drive. Mount the hard drive with the included fasteners. Close the enclosure, Plug in the power supply to the wall. Turn on the external drive. Plug in the USB cable to your computer. Browse your files.

In this case you should use data recovery software to try recovering the files and data, provided those lost data are not fully overwrtten.

Be careful: Before your files are recovered, do not attempt to save more files to the external in case the original files are overwritten.
