Bekijk de volledige versie : WL500gP unable to spin up external HDD?
I have bought a 2,5 HDD and an external enclosure based on Sunplus SPIF301 chipset. However when i connect the enclosure to the router, the drive wont spin up, its just emitting strange noises. I have also tried an Y-USB cable to increase power, but it didnt help. The drive in the enclosure is a 7200 rpm one, but i have also tried the 5400 rpm drive from my laptop - same result.
Needless to say that the drives work seamlessly in the enclosure when attached to any other device. Any idea how i could make it work with the router?
It means the wl500gp is not delivering enough power for the drive/enclosure
A powered USB hub would solve the problem.
yeah, i know that, but my point is to attach the hdd just through the USB port without additional power needed. would it be possible to get a more powerful power adaptor? i can get a 5V/3A power supply, do you think it would be enough to feed the router with an external hdd attached?
No, that wouldn't help. (unless your current powersupply is flaky)
This combo harddrive/enclosure draws too much power for the asus.
I can only suggest the following:
-Try another (preferrably shorter) usb cable
-another disk/enclosure which draws less power
-a usb stick (but that could wear out quickly)
well my, current power adaptor is 5V/2,5A... i am no expert on electronics, could you briefly explain why a 5V/3A (e.g. +0,5A more power) would not help?
as i wrote, i have already tried different drives in the enclosure. currently i am using an usb flash disk, but its too small for my purposes. i will try to get a different enclosure, just for trying
It is not just the power-supply but mainly because of the USB-chip (Broadcom) that limits the current to (probably) 100mA.

as far as i know the USB controller on the first WL500gP is from VIA. Only WL500gPv2 has an all-in-one Broadcom chip acting as a CPU, switch and USB controller

well, the router has a protection circuit that also filters away some noise as well. even if you apply 100amps to it it's not going to work and you might even damage the router.
I really could recommend a powered usb hub. I use one too, not because my router can't handle it but because it limits the chance that the adapter will break (which is a known problem). Also, 2,5A is not that much for a router with 2 usb ports... With an external hub you allow your router to have some extra juice:)
I know it bothers you, it bothers me as well... just not really anything you can do about it:(
