Windows 7: Windows 7 doesn't recognize my external HDD

You have to try and help yourself and unless we know your model number, it's very hard for us to help.

You'll find help on any support page, but you have to search for it.

http://www.samsung.com/uk/support/main/supportMain.do

Click on the link for Support, then PC & Office and select your product. From there you should be able to find a link for drivers for your chipset.

Sometimes external HDDs don't get enough grunt to power them via the USB port (could be boarderline). Different USB ports can deliver more current at 5v than others. Try using a powered USB hub as a test.

Make sure this is your laptop

Samsung

You can click on Manual-Driver-software and firmware

Update your drivers by OS type especially the chipset drivers.

Download drivers here: Samsung

Just click the Drivers link and you'll find the Windows 7 chipset drivers towards the bottom of the list.

Essenbe, I think we got there in the end.

OP,
It would be useful for others to post back if updating your Samsung laptop drivers resolved your external HDD problem.

mjf,
for ur support. I will certainly inform all of u if my problem is resolved.. but how do i verify the power issue..?
i hav already tried:
1. Rebooting with and without HDD being plugged in
2. Tried all ports (no HDD is bein recognized but pen drives r recognized!!!)
3. Uninstalling USB drives and restarting
4. Virus scan (clean)
5.
USB Selective Suspend - Turn On or Off
6. Command Prompt (
sfc /scannow) came out as no integrity violations

A power issue is only one suggestion. USB flash/pen drives require ~100mA which is a lot less than a portable HDD.
