| 279691 | 2004-10-19 02:31:00 | looked up some stuff about the hd that's inside the case www.fel.fujitsu.com Power requirement Spin up 0.90A maximum ...er.. not good it doesn't mention normal power usage though... |

Yes it does. 2.1 watts typical read/write Thats 2.1 watts / 5 v = 0.42 amps (420 mA) Just inside the 500 mA USB capabilities, but that is "typical", whereas the 900 mA is "maximum" It will vary from about 400 and up in operation I would estimate. Hence why it "disconnects" at times. My case has a socket for an auxiliary 5v power source. |

| 279694 | 2004-10-19 02:49:00 | 96mA is what it says from the power tab in root hubs properties inside hardware management is that just the amps required for it to be spinning? so when read/write it needs more... |

| 279695 | 2004-10-19 03:56:00 | Not quite right, GF . :-) It's 500 mA per port, according to the standard . There are problems with laptops which might have only one USB socket with a total of 500 mA (or the naughty manufacturers who don't supply 500 mA) . So the two USB connectors will give a total of 1A, which should work . If not, perhaps what he needs is a POS machine with USB PlusPower, which provides 5V at 6A, 12V at 6A and 24V at 6A . IBM, NCR and FCI/Berg mean business with that . |

| 279696 | 2004-10-19 04:31:00 | Yes, my bad . Many laptops do only have one port, as you say . Fitting a port powered hub would still limit it to 500 mA total, but otherwise it should be 500 mA per port . My unit will not actually work reliably with the PC mounted port, but will if I use the external powered hub . Perhaps the motherboard makers are economical with their 500 mA? And to answer the last question above, the 96 mA may well be the quescent drain, but I would not put a lot of faith in the accuracy of the 96 mA? |

I had consider voicing this oppinion but the poster seems/seemed commited to the NTFS M/S default trap. If there is a remote possability in any soho system, that you may want any compatability with other O/S F/S, N.T.F.S. is often not the best choice. Among other things it causes/can cause large problems with the many of the simple C/D boot O/S rescue systems. D. |

| 279699 | 2004-10-19 05:55:00 | um.. the Fault Tolerance ... would that help?? the hd is only ext. so.. hopefully don't need to do system recoveries on it... |

| 279700 | 2004-10-19 06:45:00 | Heni, As it is external, you may be more inclined to take it some where . So this could be more of an issue . This is why sticks mostly use fat, all-though they can be reformatted . D . |
