Hi Pierre1980!
Sorry, I oversaw your post. Here comes the reply ;D
You connect the Hard Disk over USB. It will be recognized and shown similar to a USB Stick Storage. Partitions will be used same as if you connect the HDD to the PC over S-ATA or IDE. So there is no problem with logical Partitions.
No one will ever guarantee that all new or all old HDDs will work. You can say that most of the HDDs work fine and there are no problems, but some old HDD might be a problem. I can not say if your 1,6GB HDD will work but I assume it will.
If you copy 10Gb size files you should make sure to set up the Partition to NTFS for windows, as FAT32 will not support this, it has nothing to do with the Kama Connect.
Well, how do you plan to force the faster speed over USB? If there is USB3.0 maybe. S-ATA 2 Standard is basically supported, but some features might not work. You can check the manual of the
Kama Connect 1 and
Kama Connect 2 if you like.
