I formatted a new HDD as a mac extended journaled encrypted, and then tried to install os x 10.9 mavericks on it. It was so slow that I eventually gave up and canceled everything and reformatted the SSD as mac extended journaled. I have the password, and everything seemed to re-format OK. But now this drive seems as slow as before. I tried to reinstall mavericks, and I hung in there until everything was installed, but on boot up, the thing would sit there for many minutes. I didnt time it but it was definitely not worth it. So, am I missing something? Is there a super secret way to remove encrypted formatting from a disk drive? Perhaps a key combination to hold down while youre doing all this? I reformatted the SSD as mac extended journaled, and put it in an external enclosure. And ran the Blackmagic speed test, and it show 72 write and 78 read, which I think is normal. I was using Firewire 800. So, why is it so slow when trying to put os x 10.9 on it? Any thoughts? The drive is a Sandisk X110 Solid State Drive 256GB. And the computer is a macbook pro 15 mid 2009. (I realize this is sata 2) I went back to a mechanical HDD for the boot drive and its not at all slow in an unusual way, it seems normal, speed wise. Thanks in a advance.
