Solve : My Vista PC will not backup to any USB external drive?

Answer»

I have tried I think everything too this mini pc apart put it back together and it did a backup, then never again it just locks up explorer till I pull out the USB cable. Everything else works fine. The progress bar when copying a file quite often does not go past 90% and goes red. Any help would be appreciated.

GerryDon't use explorer to copy large files to a USB DEVICE.
Unless you have a USB device that is fully compatible in every way.
This means a device  from a brand name company sold though a major vendor.

What device are you using?
How exactly are you backing up ? ?
What else is on the external HDD ? ? Quote from: Geek-9pm on April 03, 2011, 04:05:46 PM

Don't use explorer to copy large files to a USB device.
Can you document that statement please?I meant any unproven USB device. Here is a document. Literally.
The disuse is an old one, but many cheap USB devices may not be on the list of types that are known to be reliable. It is an issue with MS software as much as the hardware.

Document Name UNRELIABLE USB ADSL connections

Symptoms
During heavy data transfers using the ADSL USB modem under Microsoft Windows XP,
the USER may experience unstable connections and degraded throughput, especially
with FTP SESSIONS.
 
Cause
This issue occurs because Windows XP is dropping frames on the USB bus during
isochronous transfers.
 
Resolution
Microsoft acknowledged this to be a problem within Windows XP in an article discussing
one of its most visible effects, a distorted SOUND when USB speakers are used. This
issue is related to the USB management by Windows XP and can be experienced with a
number of other USB devices. Updating Windows XP with the XP Service Pack 1 should
solve this issue.

Yes, it was a network issue, but it was really the way MS software did the SUB device. The reference above indicates that. From this, one could expect all large streams through the USB can be an issue.
This article claims a XP SP update will fix the problem. That does not apply in this case. Instead, it would seem that  Vista may have inherited some old issues.There is no reason not to use Explorer to copy ANY file(s) to usb devices. Period. Please stop posting nonsense
