No Firewire enclosure to hand so going the molasses route... SSD in TiBook, 
boot from HD in external USB enclosure. HD shows up in Disk Utility, SSD 
doesn't. 

Same result with SSD in external enclosure, HD in TiBook (i.e. boots from 
external device, internal device doesn't show up in Disk Utility)

Before I did the above, I wanted to check if there was a clash between the IDE 
optical drive and the IDE disk drive, so I disconnected the optical drive from 
the mobo and put the SSD in the TiBook. No joy, same symptoms. 

The TiBook had booted from a Leopard installer DVD so I would have guessed the 
IDE controller is OK. (Or are there two IDE controllers in a TiBook?)

Don't know - I noticed that the nightly CCC backup from the 10·5·8 partition on 
the SSD (to an equivalent partition on the HD) was failing. (Other CCC backups 
of 10·4·11 and 9·2·2 worked OK.) CCC suggested trying DiskUtility to repair the 
disk but it couldn't - invalid tree length IIRC. Only solution was to nuke and 
pave the SSD. Then, to avoid a stupidly long reinstall, I CCCed the partitions 
back from the HD to the to the SSD.

Then, IIRC, the failure to notice the internal IDE devices started. (Uni work 
started getting heavy so I didn't get a chance to investigate until recently.)

So I guess I need to hunt for a replacement HD connector ... or is there a way 
I can test the current one in any of my existing kit?

Many thanks
