I then tried it in the Compaq but it looked like it couldn't cope (LED indicator flashing red / yellow and sounding like a power issue). However this USB bay has two USB connectors (the extra one just picks up more power) but the Compaq has only one USB port ;-( I then tried it on an unpowered USB hub on m y PC with similar results. The Acer Aspire 1353XC (I was sent as a replacement for the dropped Compaq ;-( ) was able to power the external drive on just one of it's 4 USB 2 ports ;-) Shame the Acer went back a day later because of a faulty Ethernet port .. ;-( Ho hum .. All the best .. T i m p.s. I *might* actually get round to fitting the 4.3G drive in the 50CT soon ... ** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives ---TO UNSUBSCRIBE--- Reply to any of the list messages.

I bought just the enclosure, and originally used my redundant 800MB 50CT hard drive. It will take any 2.5 inch drive up to about 18mm thick. I swop drives around, presently a 6GB drive, and when I want to re-format my present libretto drive (10GB), I format in the libretto, and then swop into the HD enclosure to copy the installation files onto the drive using my Portege laptop. Very handy, plug and play even with Windows 98SE. The DVD drive that I use is by ARGOSY, a DV730-04. Again with a 16-bit PCMCIA card, with no external power. Interestingly if you use an ac adaptor with this drive, the requirement is 1 Amp as stated on the back of the drive.

Re: [LIB] USB powered external HD
Date: Sat, 20 Mar 2004 17:46:22 +0800 From: Raymond [EMAIL PROTECTED] Subject: Re: [LIB] USB powered external HD Well my experience in getting 2.5 USB HDDs working with my libretto have been documented in the recent past in this list but the crux of it seemed to come down to not only power but power stability. The power to the USB ports on the PCMCIA card that I have don't appear to be as well regulated as say the port on the EPR. I suspect what is happening is the USB device is being a little misbehaved and suddenly switching on the hard drive in a way that the USB port doesn't like. This causes the voltage on the USB port to dip momentarily - hardly enough to even show up on a digital ammeter but enough to reset either the USB port or the USB HDD controller. As it resets, it turns the hard drive off then back on again, causes a power dip and the process repeats ad infinitum. Beyond power though there was another weird thing I had happen - even when I jumped a separate power supply into the 2.5 hdd, I still got problems, albeit slightly different ones. I've been able to run other things like 3.5 hdds (using external power supplies) and even a DVD burner, off the same 2.5 HDD 'case' electronics (through a converter cable) and they've been fine ... Of course, whilst the ports on desktops are rated at 500mA, you can in fact draw a lot more ... I've used a 750mA hard disk in my USB2.0 HDD case and it seemed rock solid, even when plugged into my libretto's EPR USB port. It does hiccup a bit though when I plug it into my desktop USB2.0 ports through a 1m USB2.0 extension cable when there are other devices on the same root hub (I'm guessing the drive is running the ports close to their limits and the drop over the cable is enough to kill it). - Raymond At 10:59 PM 19/03/2004 -0800, you wrote: Date: Sat, 20 Mar 2004 07:58:43 +0100 From: Wouter Smith [EMAIL PROTECTED] Subject: Re: [LIB] USB powered external HD But this is not a limitation of the Libretto.

Do they also require an external power cable? Matt The limitation is not what kind of card you plug in the Libretto. It is how much power the Libretto can give the card. The card can only get 500ma from the Libretto, so, assuming it uses absolutely no power itself, it can only pass 500ma through to your HD - not enough to spin up the HD in 99% of all cases.

According to USB specifications a USB-port should give 500mha (or less). Even my 6 build in USB2.0 port in the desktop can only give 500mha. USB specs do say 500ma/Port. It is still a Libretto limitation though. Someone posted earlier that the libretto puts 500ma into the Cardbus ports, which seems to be the per slot limit of the cardbus specs. You should notice that I specified Assuming the USB card itself draws no power - Those cards get hot for a reason. How much power do you think the USB chipset uses, detracting from the power that the card passes through to the USB port? Power which, even at the fully specified power levels, is hardly enough to make a laptop drive work in the first place? So if it is true spinning up a 2.5 hd takes about 1000mha, not a single USB-port in the world should be able to power it and they should ALWAYS require a power-adapter of some sort. That means all external HD producers are lying when they say it usually does not require external power (ok, wouldn't be the first time but seems unlikely). Some USB ports can deliver more current, some lucky few drives can spin up with less current, and a lot of newer enclosures have *2* USB connectors so that they can draw up to 1 amp. I've seen people mod the 5volt line to come directly from the power supply, giving essentially unlimited power there. Or am I missing something? I've read some posts on the http://www.everythingusb.com/ and there you also hear quite some stories of people requiring external power... There is a good article on manufacturer's specs vs reality regarding bus powered laptop drives on www.dansdata.com, but I can't find it right now (little short on time this morning.

While I had no problem powering the devices through an USB1 pc-card , it did not work with an USB 2 card withouth external power. Of course I tested the same configuration with another card to make sure that the card itself was not faulty. The only way for me was to come back to USB1...

I want it to be fully bus-powered, do not want to use an ac-adapter or PS2-powercable. Obviously I'd like this thing to be able to work on my Libretto 110 as well. I'm using a USB2.0-pc-card. I've read that a lot of people have problems powering them through the usb-port, especially on laptops and pc-cards. When I look at the power properties of my 'usb root hub' in the device manager I see it is capable of supplying 500mah per port. As this is according to the usb-specs I hope it is able to power an external hd. I have tried my webcam, which claims to draw 500mah, and it works perfectly. But I'm not going to simply trust this.

All Cardbus USB 2.0 cards (there don't seem to be any 16-bit ones) have a jack for external power because the card slots only provide 500mA. That might be barely enough to run a 2.5 HDD but not enough to spin it up; most drives need almost 1A to start up. I have two cards, one BUSLink and one no-name from ebay, and two external USB 2.0 2.5 drive enclosures from ebay. The drives work fine without extra power on the built-in USB 1.1 ports on several laptops and desktops I've tried. Haven't tried my Lib 110 extended port replicator yet but I'd expect it to work. My no-name card came with a PS2 power cable; it didn't provide enough power on my Thinkpad 600E but it did on my Inspiron 8200. 8 Date: Fri, 19 Mar 2004 08:46:19 +0100 (CET) From: Wouter Smith [EMAIL PROTECTED] Subject: USB powered external HD Hello all, (I'm re-re-sending this again today as my previous posts from 3 and 1 days ago did somehow not appear on the list) I am looking for an external 2.5 USB harddisk.

Matt The limitation is not what kind of card you plug in the Libretto. It is how much power the Libretto can give the card. The card can only get 500ma from the Libretto, so, assuming it uses absolutely no power itself, it can only pass 500ma through to your HD - not enough to spin up the HD in 99% of all cases.

Re: [LIB] USB powered external HD
Date: Sat, 20 Mar 2004 07:58:43 +0100 From: Wouter Smith [EMAIL PROTECTED] Subject: Re: [LIB] USB powered external HD But this is not a limitation of the Libretto. According to USB specifications a USB-port should give 500mha (or less). Even my 6 build in USB2.0 port in the desktop can only give 500mha. So if it is true spinning up a 2.5 hd takes about 1000mha, not a single USB-port in the world should be able to power it and they should ALWAYS require a power-adapter of some sort. That means all external HD producers are lying when they say it usually does not require external power (ok, wouldn't be the first time but seems unlikely). Or am I missing something? I've read some posts on the http://www.everythingusb.com/ and there you also hear quite some stories of people requiring external power... Hmmm... so the only way to find out is to actually test it before purchase! And how about those 1.8 HD's?? Like the Archos ARCdisk? Do they require less power to spin? Thanks guys for all your thoughts!
