My philips external harddrive (SDE3271) (250Gb)when we try and install the drive it keeps coming up with power surge on the USB hub port. It also keeps on beeping.

    I also have the same problem on similar Philips HDD (Requires 500mA).
    I have checked all my usb ports (each is 500mA), and tried connecting the Y-cable to separate usb root hubs, but the hdd could still not be detected.

    It does work on another computer, it just does not work on mine. I am not sure what else I need to check out. Anyone can help?

Yes , it worked.
I got my hands on a good usb powered hub and it finally worked. I tried it with a cheaper hub initially..
Thanks for the recommendation.

The power required by the DRIVE is not there,
so connect it directy to your cpu, or use a hub which also have a power option

Are you plugging directly into the computer or using a USB Hub. Cheaper USB hubs have awful data throughput. I have one that I tried to plug a sd card reader into and it would take ten minutes for a 60 megabyte file. Connect directly to a port. Or download Samsung diagnostics and make sure that the drive is in proper working order. Verifying The Hard Disk Drive Is Working Normally

I have several computers at home, and none og them can recognize this portable device. Hitachi 250 GB Mod: SDM/250RW


1) Power:

It may be the problem that occurs with a lot of USB powered devices jrherrer. Not enough power provided.

The USB cable plugged into the computer, provides signal wires for transferring information back, and forth, and also provides 5 Volts DC for power. (Two D cell flashlight batteries produce 3 Volts DC)

http://en.wikipedia.org/wiki/USB

[ Below shows the Signal pins, and the Voltage pins of the USB B Mini style connector, (Male), used to connect to the SimpleDrive Mini external harddrive,

Pin 1 is for the 5 Volts DC Positive (Wire color - Red)
Pin 2 is for the D- Signal (Wire color - White)
Pin 3 is for the D+ Signal (Wire color - Green)
Pin 4 is not connected. (Or sometimes joined to Pin 5 with a Resistor)
Pin 5 is for the Ground (Wire color - Black)

Just added info in case you wanted to know ]

From what I see the SDM/250RW has a USB port on the side, and a DC Power Jack, used for an AC adapter, also.
(Round port with a pin in the center)

http://www.hitachigst.com/tech/techlib.nsf/techdocs/0C876B7AB91B23988825773F006BEA02/$file/SD_Mini_DS_final.pdf


From what I see stated from Hitachi, and sellers on the 'net, the AC adapter may not be provided.
Many of those who provide a review state that both the USB cable, and the AC adapter is needed to provide enough power. Seems to be a power hungry external harddrive

It's a 2.5 Hitachi SATA laptop harddrive inside that external case. (The Harddrive is 2 and a half inches across in Width. Common size used for laptops)

When using an external device powered by a USB cable there are general guidelines to follow,
A) The USB cable should not be more than 2 feet in length
B) Connect the device directly to your computer, instead of through a hub, or other device, unless the USB hub has it's own power.


2) USB cable:

Could be a faulty USB cable, although I imagine you have tried different ones by now.


3) Interface Circuit Board:

The Hitachi SATA 2.5 harddrive inside the SImpleDrive Mini SDM/250RW, plugs into a small circuit board located inside that external case.

Components on the circuit board may be fried, or the Harddrive may have come loose from the interface.

Loose from the interface
To explain;
The back of the harddrive has connector pins sticking out.
The interface has socket holes which the pins insert into.

Faulty circuit board
The external case of the SimpleDrive Mini SDM/250RW can be carefully opened up, and the Hitachi SATA 2.5 harddrive extracted out.

Another inexpensive external case for a 2.5 SATA harddrive can be procured, and the Hitachi harddrive put in it.

Example of a 2.5 SATA external enclosure,

Why can't I access anything that was copied onto my Toshiba 500G external harddrive. The computer doesn't recognize the program that made any of it, even though it's the same computer.


It is very possible the voltage on your computer's USB port is not handling the load. I would buy a "powered" USB 2.0 hub, plug it into your computer's usb port and plug the harddrive into the powered hub.

WD 500 g Passport Power Surge


The power surge error means that your external drive is drawing more power than your USB port can supply. The best solution is buying a powered usb hub (USB hub with external power source) and connecting the device through that.

Alternatively (if you're desperate), you could try testing it in other ports - for instance, if you're using it in a front USB port, try the back ports and vica-versa. If you need something on the drive urgently, and you have the option, you could always try plugging it into another computer and getting the data that way, but of course this is only a temporary fix.

The fact that the drive is in a NTFS/FAT32 format shouldn't make a difference with regards to the main issue, which is power....but like I said, your best solution is unfortunately to buy a powered hub and running the drive through that.

Good Luck,

TRy connecting to other systems if your harddrive works then try purchasing a externally powered usb hub and use it.

It keeps saying power surge on hub port


Hi:
This message will come up if you plug in too many USB items that need higher power, such as a laptop cooling pad, and a external hard drive, for example.

Western Digital external USB 2.0 Problem


Buy an External USB 2.0 Hub with the 5.0V power supply. I have a TARGUS 4 Port Hub. MY WD2500XMSB works fine thru the HUB, but will not work using any cable (even the one that came with it) when directly connected to the USB port on my computer. The power consumption of passports sometimes exceeds the .5 milliwat rating for the ports and ccause the port power to interrupt (see USB 2.0 specifications). The external hubs with external power have a higher power output usually an can power the passport drives. CW Rumsey

Western Digital Passport 160 GB external HD won't load.


WinXP SP2 blocks the use of the drive because it thinks it draws too much power. But there is a simple procedure to override this (from WD site):

"Problem:
Under Windows XP, an error message of "Power Surge on Hub Port" or "USB device has exceeded the power limits of it's hub port" is displayed when connecting a USB device to a USB port on a computer or Hub.

Cause:
Under some computers, USB devices are only allowed to draw a maximum of 500 milliamps (mA) per connection from the USB port on the computer system or from a USB hub. Under the Windows XP Operating System, with the release of Service Pack 2, if a device attempts to draw more than this (500 milliamps), a USB port balloon message is displayed to indicate this over current condition. When connecting a USB device that draws power from the USB bus, a very brief over current condition is sometimes detected by the OS, and the warning message is displayed.

Resolution:
This message has no affect on the functionality of the USB port. The USB hard drive should still function correctly on the USB port regardless of the error message. To prevent the USB Power Surge Alert message from displaying, please complete the following steps:
Click on Start.

Click on Control Panel.

Double-click on the System Icon.

Click on the Hardware Tab.

Click on the Device Manager button.

Click on the + next to Universal Serial Bus Controllers to expand the selection.

Right-click and select Properties on any listing that displays USB UNIVERSAL HOST CONTROLLER.

Click on the Advanced Tab.

Check the box that says: Don't tell me about USB errors."

This works fine, and the drive works fine afterwards. I suspect it actually draws less power than they say. Maybe it has a brief power draw spike on startup, but it's running power seems less. In any case, it works fine without the Y cable. I do think it is tacky that WD doesn't give the cable for free, since my $7 Sabrent 2.5" Hard drive enclosure came with a y cable.

But most likely the drive will work fine for you. It is a lovely quiet drive, and takes up no space at all.
