No worries matey.  I I tranferred so much stuff in the last few day I was just trying to speed things up.

To help things out in the future I have just bought a USB Adapter.  I can just drop a new hard drive (Data) in it and plug it into any machine to Upload/download/transfer data from any machine/laptop to either a 3.5 or 2.5 ins hard drive before in stalling it into my server.

Just bought one of those myself to get out of a sticky situation with some old MS-DrOSs machines that I have found myself having to resurrect at work.

24 quid from Maplins, does IDE, 2.5"IDE and SATA and even comes with a little power supply. Did the job perfectly. Now, if I could stop Windoze corrupting the DOS partitions with newfangled stuff DOS doesn't understand... Hmm. Mount them under Linux I will. :y

I have just bought one of these and cheaper in the UK.  Could only find this one on fleabay, will make things a lot easier for me.

Also found a dual drive version whilst I was looking.

For those who dont know

Hubs: Multicast all ingress traffic on all egress ports (what comes into one port gets sent out on ALL other ports)

Switches: Learn Mac addresses and hence dont multicast as standard. They forward to the correct learn;t port.

Routers: As per switches but with additional functions such as layer 3 support (IP layer), IP address allocation etc etc
To everyone new to networking, the above is a good guide.

Be aware that there is some crossover between them though - such as L3 switches, which are switches with (normally limited) simple routing built in.  As MDTM said in earlier post, hubs that can do FD exist, though they are actually (normally managed) switches set to send all data to all ports on the configured vlan/segment.


This is all enterprise class stuff, and if you have to deal with it, your corporation will normally give you some training.  In the consumer space, all you will find are:

Hubs (getting rare now, as switches cheap) - 10 or 100, half dplx only
Switches - 10/100/1Gb, full and half duplex (be aware some cannot do 1000HD, but then as every Gigabit NIC can do 1000FD, thats not an issue)
Routers - normally DSL or broadband simplistic router, often with a 4/5 port hub or switch hanging off the back of it. If wireless router, it has built in AP than normally hangs off one of the ports internally.
