I just found the FAQ page on the Seagate website that talks about their CF microdrives. There has been much talk in the Aximsite forums about these drives as well. Of course, when Geeks.com started selling a Seagate 5GB MD for $99, I started to investigate rather than get burned.
If you look at the bottom of the Seagate FAQ page
http://www.seagate.com/support/kb/di...to_cf_faq.html they have a picture of both their OEM and their retail drives. It appears that Geeks.com is actually selling an OEM drive, even though they state "It works in every device that accepts Type II CompactFlash cards!" but Seagate states they don't guarantee this.
And of course, some Aximsite members have found that these drives don't necessarily work in the X50. So, buyer beware.
