I installed SSD in place of Superdrive, formatted Ext,Journ, restored MtnLion from TimeMachine, renamed old boot partition on 1TB internal because it confused time machine, went to SysPref->Startup Disk - Selected SSD drive and clicked restart. In fact did this a couple times.


18s white screen to apple, another 20 seconds to login screen.


btw, SysPref->Startup Disk displays 1TB SnowLep, 1TB Mtn Lion, and SSD Mtn Lion (highlighted)


1TB internal has SL partition, ML partition, a Data Partition, and a Mtn Lion recovery partition
SSD has ML partition and I think a Mtn Lion recovery partition (not sure how it got there since I didn't do a clean install to the drive)


When I boot using the alt/option key there are two Recovery.8.2 disks shown. I am guessing one on the 1TB internal, and one on the SSD. When I boot from DVD I see two entries in the log name: disk2 partition:0. When I use DVD disk utility there is only one "disk2" shown with 1.15GB Boot OS X disk image marked as "Startup Disk". Is having two recovery partitions named the same a problem?


Any ideas why it is so slow booting?

    I've noticed that the more drives that are associated with the system the longer it will take to boot. Do a check in About this Mac and see what the negotited speed is for your SSD. I've read some posters who say by installing into the DVD slot they only get 1.5Gbs negotiated speed instead of the preferred 3Gbs.

    What is the speed of the optical drive port? You may have a slow SATA port for your SSD and that's why it's slow. You have a 3G SSD on a 1.5G port or possibly worse, a PATA port. Were I you I would have done this:


    Drive Preparation and Installation for Lion/Mountain Lion


    1.  Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button. Select Disk Utility from the main menu and click on the Continue button.


    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.


    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.


    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.


    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.


    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.


    7. After formatting is done quit DU and return to the main menu. Select Reinstall Lion/Mountain Lion and click on the Continue button.


    Once this is done you can consider restoring data from your backup. Although you may wish to check your startup times. But your SSD is not going to achieve its best speed running off the optical drive port as opposed to running off the main SATA port used by your HDD. You might want to think about switching their positions.
