I bought 3 tb segate internal harddrive and then bought startech enclosure for it. when i plug the hard drive into my macbook pro(2009) running 10.8.2 and it does not recognize it. Then i booted my laptop with windows 7 and it recognizes the harddrive, i installed macdrive on windows and partitioned it as HFS+ but it still doesn't recognize it. Then i plugged in my friends 320gb wd external harddrive wich is partitioned as FAT32 and it works on his MBP 2009, but it wont recognize on my when i am running 10.8.2. It would work when i run windows 7 but not when i run 10.8.2.
I dont see what the problem is. Also when i plug in regular jump drive it easily recognizes it, can some one please help me out.

Baby Steps,

first, plug your Startech enclosure into your MBP.
Now go to Disk Utility and check to see if it appears there.

If it does, select it and format it as Mac OS X Extended (Journaled)

If you succeeded in that, does the drive now mount on the desktop?

Have you tried a different USB port on your MBP?

I assume this enclosure has its own power supply?

In reply to: Baby Steps,

It does not appear in the disk utility, i used macdrive on windows to format it to HFS+ which is i guess same as journaled, It still doesnt recognize on mac os. I also tried resetting ram and all that basic stuff. And yes it has its own power supply and on the enclosure website it says the MAC is supported. The only thing i dont understand is, that when i boot my MBP on windows the harddrive works but when i run it on mac os it doesn't show up.

Try Tuxera NTFS for Mac on your Mac Book.

I installed it to transfer files from/to Windows drives formatted with NTFS.
(Which may have been how the drive was originally formatted, check the box.)

NTFS for Mac is "try before you buy" so you have nothing to loose.
