8/25    I have a portable USB HD (2.5") that I built myself with WD HD
        and an enclosure. On some systems it won't power on via the
        USB cable, it'll try to spin up, but does not successfully
        spin up. Could it be those machines do not provide enough
        power via the usb output? On one machine that fails to power
        up, I tried the fire-wire cable, it powered up fine. It also
        powers up fine on my machine via USB. Thanks.
        \_ Yes, exactly.  Not all USB ports are made the same.  I have a 4
           port USB hub that will power a mouse or other small device but
           nothing with a real power need "but it should".  Those systems are
           simply not providing enough power via their USB ports.
        \_ this is a well-known issue with some enclosures, see any newegg
           reviews of lower-rated enclosures.
           \_ Hmm, what would you consider a 'good' enclosure? My
              first one, the BYTECC HD-201U2, highly rated at new-egg,
              was a piece of crap. Dead on arrival, and the
              construction was also cheap. Drive hold in place by foam
              padding? My current one is a Macally PHR-250CC, much
              better designed and made, from the IC board to the way
              the drive is secured to the board to the way the board
              secures to the case. Could also be my drive, but I
              specifically picked one with average RPM so it won't
              suck as much power.. -op

                 (fixed the URL)
                 Vantec Nexstar 3 black (also in red and navy blue)
                 I got that for my gf, and it looks really nice, but she hasn't
                 used it much.  I purposely didn't order the BYTECC you got
                 because it looked cheap from the photos and someone posted
                 about a screw getting stripped.  Oh well.
                 Anyways, that was my choice for "best USB 2.5 enclosure" from
                 my research in early July.
                 I just noticed a new review saying it corrupts data.

                 Oh well, looks like the Macally is what you want.

                 I have the AMS Venus DS3 3.5" enclosure, use it ALL the time
                 and never had problems, so hopefully the 2.5" is the same.

                 time and never had problems so hopefully the 2.5" is the same.
        \_ There are "powered" and "unpowered" USB ports.  The former supplies
           more juice than the latter.
        \_ Even with a powered USB port, the spec only requires that it is able
           to deliver 500mA @5V, or 2.5W.  There's no way you should expect
           the USB port to power a hard drive.  That's while all HDD enclosures
           have seperate power supplies.
           \_ ^all^all usb -- I have yet to have problems with my Firewire
              HDs getting enough juice.

        only 60% full. What the heck do people put on their HD these

        \_ Also, disk drive manufacturers advertise "raw" storage, while
           your O/S measures usable storage. You lose quite a bit to

        drives not "Fast Indexable", it's the explorer that's funky. Here
        is one solution. Kill explorer and then run it again. You can use
