Hei, I'm quite outdated in external HDD.

As you can see from my siggy, I've bought 2.5" HDD all these years due to portability issue.
Now as I've less travel, I need a large externall HDD to use along with my lappie.

Can Anyone tell me:
i) Is Seagate famous firmwire problem causing HDD failure exist in External 3.5" HDD? Should I get WD instead?
ii) I'm considering 1.5 TB 3.5" Seagate External HDD since it is quite cheap (saw RM 485). Is Seagate FreeAgent Xtreme and Home got any difference? If you suggesting WD, I cant see any WD 1.5" External HDD by the moment.

Thanks.
