Two network switches free to a good home
by Srdjan Todorovic 15 Feb '13

15 Feb '13

Hi all, I've got 2 network switches free to a good home. They are untested (fans spin and LEDs light up, but not tested network ports), but I have no reason to suspect they are duff. They are: 1. CentreCOM FS716 16-port 10/100 mbps switch. 2. Netgear FS518T 18-port switch. 10/100 mbps for ports 1-16 (I think) and 1 Gbps for ports 17 and 18. Both do not have the auto mdix thingy so you will need correct patch ethernet cables (port 16 has the ToPC / ToHub toggle button on both switches). Both are powered using mains kettle cable (not supplied). Both have fans (the Netgear is a fair bit louder). Both are about the same size, just bigger than A4 paper I'd think, and metal cased, about 1U high. Google the dimensions if you want. I can bring them both in to this week's ALUG meet in Norwich. If anyone wants them, let me know so I can stick them in the car for the meet. Regards, Srdjan

I could use Scrapbook to save web pages but is there something I can use to save multiple pages or entire sites? It's just for personal use. Any ideas? Bev.

CAD "lite" for DIY projects
by Mark Rogers 14 Feb '13

14 Feb '13

I'm looking for a simple CAD tool for basic DIY projects. The project I have in mind at the moment is a wall-to-wall bookshelf comprised of 40x35cm "boxes", made from 18mm MDF, laid out like bricks (ie each row offset 50% against the ones below/above it). I want to get a feel for what it will look like, and want to be able to change things like the MDF sheet widths (eg what would it look like if the higher rows were made from 12mm MDF instead), box colours, etc. 3D would be great but non-essential. I got some way mocking something up in Inkscape but it's not really the right tool for the job. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

RAID advice
by Chris Walker 12 Feb '13

12 Feb '13

Hopefully somebody can give me some advice. I have an Edimax NS2502 NAS device with 2 x 1TB drives in it arranged as RAID 1. When I first had it, I started to fill it up and then wanted to check that everything was working ok so removed one drive and saw that everything was still showing. I then removed the first disc and refitted the second and saw that everything was still there. Satisfied that it was all working, I have left it running ever since with the 2 drives. But ever since my experiment, the drive lights on the front have continued to flash as though they're being accessed. Worried that I might have screwed something up, I looked at the options and found one called 'Fix RAID'. That is there apparently for use if one drive fails. Should I use this to make sure that everything is 'synced' across both the drives in my box? I've tried googling this for advice but all I've found is the acknowledgement that the option is there but nothing on whether it should be used or not. Any help appreciated.

Re: [ALUG] External hard drive (temporarily) kills PC?
by Peter Alcibiades 08 Feb '13

Have you tried using another usb lead? Could it be that there is something dodgy about the connectors which when the plug is inserted with power on screws everything up, but once the plug is seated, will work ok, at least for the time being? Presumably it does not happen with other external drives, which would rule out some malfunction with the socket. Or one could try with different sockets to make absolutely sure. I can't think of any other explanation. It can't be the drive itself or it would happen regardless of when power comes on. If it happens with other leads, I would return it (though I can't think of how the drive itself could be defective in a way to cause this). I would also try it first with another computer and see if it does it to every one. Have you done that? Very strange. Al

External hard drive (temporarily) kills PC?
by Srdjan Todorovic 07 Feb '13

07 Feb '13

Hi all, I just got my brand new Western Digital Elements external hard drive today, and it seems to like killing my PC. I plugged in the power from the supplied power brick, hooked up the USB and BOOM!, usb keyboard and mouse die, as does X, as does whatever music I was playing. I have to press the reset button on the PC. It keeps doing that if the external hard drive is powered up and you are connecting. I've booted up now with the USB connected and then plugging in the power, and seems fine. Can anyone please suggest what's wrong and how to fix it? Thanks, Srdjan

Quite large, have to check if it will fit. Quiet PC carries this as their sole northbridge cooler. Apparently soutbridge is not a problem as its heat output is very low. So thanks, will have a go.

two weeks or so, and it dies again!
by Peter Alcibiades 05 Feb '13

05 Feb '13

This is weird and part of the ongoing power-down problem. It goes two weeks continuously. Then this morning as I send an email, down it goes. On-off switch has no effect. Change the leads, still no effect. Leave it for a half hour, come back and it starts perfectly. This has to be some sort of heat reset, doesn't it? But the thing I cannot understand is why it should just suddenly happen. gkrell shows cpu temps of 35. The bios at startup showed a bit over 40. I did have a resistor from quiet pc to slow down main fan speed, which has been fine for a couple of years now, but on the offchance I removed that. However, given the latest crash it cannot really be that. Looks like there is an i5 in the future of this case, which is a pain and not cheap either - by the time we get new board, new processor, and a proper shuriken cooler.... Can you think of anything else to try? Al
