Just wondering what drives ( both SSD and regular) people find are most reliable for use in the dataport?

I've got 4 drives - 2 x OCZ vertex 60GB ( now working fine ), also a 160GB seagate which falters during playback and won't auto repair files in DVR 2.0, and a 250GB Samsung. The Samsung mounts fine and records faultlessly, but whatever I do I can't get my macbook pro ( or any other mac) to recognize it.

After copying off data, I always reformat the drive.

What does anyone else find works best for them?
