My previous Imac bought in 2008/09 has stopped working. On switching on I get the usual Mac noise as it is starting up but then nothing apart from a screen which after starting up has a 4 inch wide light blue line in the middle from top to bottom, the rest is white each side. Does that mean that it is dead or just wounded. I have a new 27" fusion drive now, but there is some stuff on the old Imac which never came across from the external drive. Is it repairable or should it be ditched. If fixable, cost?

You really expect answers to those questions, at this stage and with the supplied information?

What OS are you running?
What diagnostic or repair software do you have?

All things are fixable, it depends on how much time, money and effort you want to put into fixing them. Who knows what is wrong with it? That is a big question. That sounds like a graphics logic board problem which is not likely to be economically repairable. That's my gut feeling, I doubt if it will be worth tackling.

To get your stuff off the computer, try putting it into target disk mode, connect it with a FireWire lead to your new iMac. If successful it will show up as an external drive and you can then copy off what you want.

Alternatively pull the HD out and put it in a caddy.

The last operating system was Mountain Lion. No idea regarding the next question. If I was explaining how to refurbish the difflocks on a Land Cruiser 80 series that would be much easier. What is a Caddy?

Something like this https://www.amazon.co.uk/gp/product/B06 ... _i=desktop an external enclosure to put a HD into.

It is an enclosure for a "naked" hard disk.
The idea is to remove the hd from your iMac, and place it in such an enclosure - and then simply have that as an "external" disk, from which its contents are available for transferring to a new computer.

My guess, also, is that it would be very expensive to repair your computer - and for what?

Try TDM first! If you can make the connection between the computers with a FW cable (which is doubtful because I don't think your latest iMac has a FireWire port) - or a Thunderbolt cable, which is the other possibility for TDM - (but the 2008 iMac certainly doesn't have a Thunderbolt port) - but if you can find another Mac or even a PC with a FireWire port and a FW cable to connect the two, then TDM is the obvious and easiest solution to get your data off. Given the above it would take you 30 seconds to connect.

But you'd have to put the difflocks on on both iMacs! Otherwise there could be a lot of wheel slippage.

There were a lot of graphics chip problems with computers of that era. I bet it's a stuffed graphics chip. And that is soldered to the logic board and therefore you would need a new logic board. Perhaps if you just change the gearbox oil on it, it might work.

Quote:
How to Use Firewire or Thunderbolt Target Disk mode

Turn off the ‘target’ Mac (the 2008 iMac)

Now connect both Macs to each other with a Firewire or Thunderbolt cable

Boot the target Mac while holding down the ‘T’ key until you see a Firewire or Thunderbolt icon displayed on screen, this signifies that target disk mode is detected and working

In a few moments, the target Mac’s hard drive should appear on the host Mac’s desktop, allowing you to access it like any other external drive

When you are finished, safely eject the target Mac as if it’s any other disk, briefly press the power button to shut it down.


In this case I doubt you will see the FireWire symbol on the screen if the graphics is nadgered but holding the T key for no more than 15 seconds should be ample. But it might still work anyway. It's the quick way to get at your data. The labour intensive way is to open the computer up and take out the drive as mentioned but it will be a 3½ inch drive so you will need a 3½ inch caddy ...

No firewire on iMacs since 2011 according to mactracker. Thunderbolt to firewire adapters are available though.

Target disk mode still works on newer Macs via USB-C and ThunderBolt...

I never said there was, just reporting that Target Disk Mode was still alive and well - note they've dropped the "FireWire" part of the name to reflect this.

It's great to hear that Apple are continuing target disk mode into the future, it is a very valuable feature to have and would be such a shame if they ditched it. If Channel wants to connect the two computers he'll need an adapter that does the job, otherwise - borrow a compatible Mac to offload the data - or take the hard drive out, of course.
