You just can't argue with the ability to connect an unpowered external hard drive to your phone. Splendid!
Tried it on my Samsung S2 640gb hard drive (see below), it didn't work when it was formatted with NTFS (I suppose that makes sense). Works ok on FAT32 though so all's well. Who really has any one file that's bigger than 32gb anyway?
Works fine on my Sandisk Titanium USB stick too. Very handy for work and holidays!Sandisk 4GB Ultra Cruzer Titanium - Retail PackDrive S2 2.5034 Wine Red 640GB Samsung
