Get more memory at Crucial.com!

Before installing Virtual Server 2005 R2 on my already overworked server (actually, its just a PC) which acts as a domain controller, DNS server, DHCP server, RIS server and handles a few file shares (admittedly on a small network – I’d never advise running a business on a single PC), I thought I’d better put some extra memory in it.

I find it impossible to keep up with PC hardware, and at the danger of turning this post into one large advert, I was really impressed with my experience at the website. In a few clicks, I was able to use the Crucial Memory Advisor Tool to identify the memory options for my aging Compaq Evo D500SFF and, although I didn’t use it at the time, they also have a system scanner which can be used to identify upgrades for a specific system (I’ve just run it now and it correctly identified the system which I’m using to write this post).

Another area of the Crucial site that really impressed me was the help text, which enabled me to understand the various memory types (so I could decide whether or not to simply swap some RAM around between my various systems).

To make this post a little more balanced, I should mention that Kingston Technology also have a memory search tool but my experience was that the Crucial version was faster to use and the prices were lower (I suspect this is because Crucial sell direct whereas Kingston redirected me to a third party to actually buy the RAM). Crucial also sell flash memory cards and readers, USB flash drives, graphics cards and printer memory,as well as offering free UK shipping by Royal Mail Special Delivery for orders over £25 and guaranteeing compatibility of the memory purchased (as long as you have used the Crucial Memory Advisor Tool).

Checking how much power a USB device requires

I have a number of USB-attached hard disks that I use for portable mass storage, backups, etc. Very occasionally, Windows XP will report that there has been a power surge on the USB port and that it has been shut down. This can happen when the total number of devices attached to a USB hub (internal or external) exceeds the total power available. I’ve always treated that as a minor annoyance (and as these disks have two USB connections and a Y-shaped cable, I can simply use two ports) but then a few days back I noticed something I’ve never see before – the ability to view power details for (or more precisely current drawn through) a USB root hub:

USB device power draw

As can be seen in the example above, my scanner is using the full 500mA on its port, but there is still a port available which could potentially provide another 500mA. To view this information, open Device Manager from the Computer Management MMC snap-in and expand the Universal Serial Bus Controllers node. There will normally be a number of controllers listed, along with some devices and USB root hubs. Each USB root hub should have include power details within its properties.

Checking my IEEE 1394 (FireWire/i.Link) controller doesn’t seem to offer the same facilities, presumably because it doesn’t have the same concept of a root hub.

Mini mouse (not the Disney variety)

For some time now, I’ve been looking for a miniature mouse to take with me when I’m on the road and save my aching hands from the pain of trackpad/touchpoint. A former customer of mine has a fantastic IBM optical 3-button travel wheel mouse, but at the time I looked into getting one it was too expensive. Then, yesterday I was in PC World (sorry… it was an emergency) and I saw an optical 2-button mini-mouse which was both inexpensive and “different”. A £9.99 optical mouse coloured like a bee!

My son loves it (even though, at just over one-year old, he doesn’t understand what it is, he was soon holding it correctly and clicking). My wife thinks it is cute. I just like it and find it remarkably easy to use, despite its diminutive proportions.

Handy KVM solution

A few months ago I sold my KVM switch on eBay. Now I’m running out of desk-space again…

To be honest, the old one was too big, too noisy, and had 12 feet long KVM leads making it a bit over the top for a desktop solution but yesterday I picked up a Linksys integrated KVM 2-port switch at RL Supplies.

Linksys KVM2KITWith built-in cables, drawing power from the PS/2 port on one of the PCs, and no software required, this is an ideal solution for letting the port replicator for my work laptop and my desktop PC share the same keyboard, mouse and monitor (at resolutions up to 1920×1440). I just hit the Scroll Lock key twice to switch between PCs and my USB mouse even works with it (using a USB to PS/2 converter). Definitely worth considering by anyone who needs to find some extra desktop real estate.

x64 finally comes of age

To be honest, I got a bit confused with the various 64-bit CPUs (like why didn’t Intel and HP’s Itanium take off, but AMD’s AMD64 did and Itanium 2 looks like it will too), but whatever the hardware issues, it seems that x64 software has finally come of age. Paul Thurrott reports in his Windows IT Pro magazine network WinInfo Daily Update that, at the IT Forum this week, Microsoft announced that the Longhorn Server wave of products will be 64-bit only (except Longhorn Server itself, which will be available in both 32- and 64-bit flavours). That means that, for example, the next version of Exchange Server (codenamed Exchange 12) will only run on a 64-bit platform. There’s no news yet as to what is happening on the desktop (except that it seems, like Windows XP, Windows Vista will be available in both 32- and 64-bit editions) but it looks like I’d better get saving for a new PC…

Comparing Intel processors

I’ve spent most of today comparing a variety of PC workstation specifications from various manufacturers. This isn’t normally a level of detail I get involved in so I found the Intel processor product numbers information particularly useful for comparing features between the various CPU types, particularly the discover processor technologies multimedia presentation.

Missing disk space

A few months back, I was chatting with my Dad about his PC (you know, one of those “family IT support desk” jobs) and he was wondering what had happened to all of his hard disk space. David Chernicoff has written an article for Windows IT Pro magazine about the case of the missing disk space and it’s worth a read. I certainly found it interesting – especially the bit about true sizing cf. disk manufacturers’ idea of storage units.

RTFM…

I haven’t really come across Fujitsu PCs and servers since I left ICL in 2000; but now I’m back on board at Fujitsu Services (same company – different name), not surprisingly, my new work laptop is a Fujitsu Siemens Lifebook S7010D. It seems like a really good notebook PC (although I find the absence of quick launch function keys in order to make room for a PIN-entry security pad a little strange – I would have preferred an integrated fingerprint reader like those offered on selected IBM ThinkPads).

When I brought the laptop home and the onboard wireless LAN card didn’t detect any of the four wireless networks within range of my home office, I naturally assumed it was broken (based on previous experience with a Dell Latitude D600); but then I had a similar problem with Bluetooth communications so I did the unthinkable (for any self-respecting IT infrastructure consultant) – I called the IT helpdesk.

In what must have qualified for my most embarrassing helpdesk call ever, I found out that there is a switch on the front of the PC to enable/disable the wireless LAN and Bluetooth module. Once enabled, everything sprung into life. Doh!

Maybe next time I’ll RTFM.

Why consultants should leave hardware alone…

Today has not been a good day for me and computer hardware.

It all started a couple of weeks back, when I dropped the bag in which I carry the Dell Latitude D600 that I use for work. When I took the computer out of the bag, I had cracked the case on the edge of the screen, although everything was still working. Of course, this type of damage is not covered by warranty (and I can hardly blame Dell on this one) but when I e-mailed the internal support department they had an identical computer over which a colleague had spilt red wine. So, it should just be a case of swapping over the screens and my laptop will be good as new – or that’s what I thought…

Once I put it all back together, I powered on the computer and… smelt burning electronics, combined with wisps of smoke from the motherboard. So that was the end of laptops 1 and 2.

The guys in internal support are helpful (and do have a sense of humour); luckily they had a spare D600 which was working, although the previous user had reported a problem with the display that no-one had managed to look at yet. I slid my original hard disk into the spare unit and it all fired up. Windows Server 2003 plug and play detected a hardware change (just a different wireless network card) and I was away – except that the display switched off after a few minutes, and attaching an external monitor didn’t make any difference. After half an hour on the phone (during which I reseated the monitor connector and restarted the computer several times, with the screen going blank on each occasion after varying lengths of time) I managed to convince Dell that a new motherboard was required and they are dispatching an engineer in due course. In the meantime, I need a computer to work with and so, on to laptop number 4, on which I am typing this post (it has a dodgy trackpad and the DVD drive makes some funny noises, but I can live with that for a few days).

Now, the combination of my recent iPod purchase (so far I’ve managed to rip about a sixth of my CD collection and I’m up to 11Gb of MP3s) and my hobby as a photographer (over 2000 6-megapixel images in the last 6 months) means that I have run out of hard disk space on my home PC, so this morning I bought a 250Gb Seagate Barracuda hard disk from RL Supplies. I was understandably a bit nervous about installing new hardware after the debacle which destroyed 2 laptops and disabled one more – my IT Manager suggested I look out for at least two pairs of magpies on the way home, hang a horseshoe over the door, get hold of some lucky heather and find a four-leaf clover before even opening the case.

I quickly hooked up the new disk and then, armed only with an MS-DOS boot disk and a copy of Symantec Ghost, I cloned my old disk onto the new one in half an hour. Then I removed the original disk, rebooted and after a quick restart to let Windows XP sort itself out once it had detected the hardware change I was away again with a 625% increase in capacity.

Phew! Now I think I’ll stick to software for a while…

Biometric USB flash drive – how cool is that?!

This content is 20 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

I know that it is just a logical evolution of the humble USB flash drive and the decreasing cost of biometric security (even my local gym uses a fingerprint reader now for members to sign in and out) but last week Thomas Lee showed me the Trek ThumbDrive Swipe, which combines fingerprint swipe sensor technology with flash memory based USB storage. Fingerprint security on a USB stick is cool. Now all I need is for someone to invent something to stop me losing mine all the time…
