Windows 7 to external Harddrive 'forgetting' item copied

[Ben Rogers]

Hi there,
I'm having a problem copying files to my external hard drive (Fijitsu/Siemens)formatted in NTFS, with 758 GB Free.
I complete the following process: 1. Open the hard drive

1. Copy a file from my computer
2. Paste the file onto the hard drive

The file appears to have copied to the external hard drive, as I can see it in the hard drive's explorer window.
However when I remove the hard drive from the PC, and the reattach it, the file is no longer on the hard drive.
I've waited minutes before removing the hard drive, so don't think that the computer hasn't had 'time' to copy it.
Does anyone have any thoughts what the issue might be?
Many thanks

Ben

Is your external drive connected via USB?

If so, in the system tray locate the icon to "safely remove hardware and eject media" and right-click. Choose eject and wait for a message that it is safe to remove.

Note: If you have multiple USB storage devices then you will need to pick the right one.

Do that each time you disconnect and let us know if files still disappear.

Or you could disable "Delayed Write" on your USB Hard drive. The article HERE tells you how to do it.
