Hi All, I have a late 2009 i7 iMac and recently upgraded the main HDD to a 2TB disk and while I was doing it I decided at a later date I would come back and replace the optical drive with a SSD......well here I am.. So I got a caddy and replaced the optical drive with a Kingston 128Gb V+100, booted from a firewire drive with my lion install files on and proceeded to install Lion. I went into disk utility and partitioned the drive (extended journal and GUID) then set off the install. It does the first 3 minute part ok then when it reboots to continue the install I get the apple symbol then I get the no entry style sign flashing. So I booted into my main 2TB HDD went into disk utility and repartitioned the SSD then I ran verify disk which came back with errors (invalid B-tree node size) and told me I need to repair the disk, so then I tried to repair the disk which again came back with the error that disk utility couldn't repair the disk. So i'm at loss, my next step would be to install it while connected to a USB caddy then if that works drop it back in the mac.....BUT i'm beginning to think that either the drive is faulty or for some reason the mac doesn't like the SSD. Anybody experienced anything similar?
