I use a 640 GB StoreJet Transcend (0x2329) with ZEVO Community Edition 1.1.1 on OS X 10.8.2.

Question

Is this drive Advanced Format?

Background

I submitted a request for technical support to Transcend but the first response was gibberish so I don't expect a reasonable follow-up.

Models at http://www.transcend-info.com/Products/CatList.asp?LangNo=0&ModNo=293 are similar but different sizes (not 640 GB). Mine is probably 25M2 (TS640GSJ25M2):

Unless I'm missing something, nothing currently in the Transcend support area tells me whether the drive is Advanced Format.

From System Information in OS X 10.8.2:

History for the ZFS pool shows creation in March 2012 – 

macbookpro08-centrim:~ gjp22$ zpool history zhandy | grep create
2012-03-14.17:29:37 zpool create -f -O compression=off -O copies=1 -O casesensitivity=insensitive -O snapdir=visible zhandy /dev/dsk/GPTE_1928482A-7FE4-482D-B692-3EC6B03159BA
2012-06-22.15:51:16 zfs create zhandy/Pocket Time Machine

At that time I almost certainly used ZEVO Setup Assistant to create the pool.

macbookpro08-centrim:~ gjp22$ zpool get ashift zhandy NAME    PROPERTY
VALUE   SOURCE zhandy  ashift    0       default

If I discover that the drive is Advanced Format, a different ashift value will be appropriate.
