Boot from it
Of course , thanks ...my brain is on go slow all day now

, time for sleep thinks me ...but yeah , I booted from it , seems fine ...the drive read/write noises seem a little loud now that I've been sat with it a while , maybe noticing them more but still ...there you go .
I have noticed a small speed boost loading web pages but I wasn't expecting massive improvements as the G3 iMac I'm on had a HD upgrade before I got it ( Maxtor 80Gb) but ye , so far so good , the grinding noise will possibly
be an issue I think when I get the new Mac and start tasking the disk with Logic and such ..hmmmm , grinding noise on read/write ?! normal or no/ anyone else got one of these or thoughts ?
EDIT > the grinding sound is happening quite a lot , ....should a drive sound like this?
The Maxtor in the iMac makes a similar noise( albeit quieter) , I put that down to age !?
Update> Nah , I
think it's ok ,now I've moved the drive to another part of h desk and not in an alcove it is much quieter (obviously I hear you say !) but there is noise none the less.
Maybe just a teenee tiny bit of the dreaded
new product buyer >paranoia going on !! ...
UPDATE> Boots from the drive without problem , although it takes a minute longer booting from the external ...because of the G3 maybe ??
please see update further down page >>>>
