Disk Utility Doesn't Recognize SSD

Hello all:

I've been reading through the forums (and elsewhere) and want to be sure I ask a question specific to my issue before returning this drive.

I'm attempting to install a Samsung 840 Pro SSD (256g) on my MacBook Pro 2.53GHz (15-inch Unibody w/SD card slot - June '09).

My previous HD failed, so I replaced it with the SSD, used the install DVD to create a bootable flash drive, and attempted to access the SSD for formatting from both the install screen's Disk Utility and the DU from the flash boot. Neither will recognize the SSD.

Before I return the drive, would anyone recommend trying an external enclosure to attempt the format?

If so, do I need a specific product, or can I function with any enclosure?

Also, why would it make a difference?

If anyone needs additional information, please let me know.

Thanks,

Ryan

Well in all Un-fairness you have to look at who you are dealing with. Hey it's an Apple product an as that "It Just Works", Sometimes.

Glad you got it fixed and enjoy the SSD speed.

I'm not sure the exact process of checking drives from the 'Genius Bar' side, but when I went in today, stating clearly that I believed the issue to be the cable, the technician ran a test and acknowledged that the cable was not functioning at capacity. The only reason for me to be 'frustrated' with the service was that the initial recommendation was to replace the HDD, even though we now know the drive was fine.
