[Scottish] usb2 hard drive not being recognised anymore

[Thomas McLean]

Hi Martin/all,

Just an update, I installed ubuntu onto another machine and tried it
that way and the exact same messages appeared (different kernels).

So I says stuff it time to open the casing. I done it without breaking
the warranty sticker, so thats a good thing. I mounted it into the new
installation of ubuntu and then formatted it to ext3 and tried it on my
other PC and that worked fine under ubuntu. It's mounted and working
perfectly. I've not tried the other drive (format and mount procedure)
as yet but will get round to that shortly.

I'd imagine that the other drive will be working too and maybe just the
casing is broke somehow. The casing is just lying beside the computer, I
actually do prefer the drives being inside the PC for speed issues etc.

Thanks for all the replies tho', it's very much appreciated.

Cheers,

Tam.
