I have 4 HDDs:
- Maxtor 3.5 SATA 160 GB
- Fujitsu 2.5 IDE Laptop HDD 40 GB
- Western Digital 3.5 IDE 40 GB
- Maxtor 3.5 IDE 80 GB

I was very happy when I buy Kama Connect 2 and I start making back-up and store my old files. I use ViceVersa Pro for synchronize my files with CRC verification option activated.
I have no problem with my 3.5 SATA HDD and with 2.5 IDE HDD; everything works fine and CRC calculation in OK, but with both 3.5 IDE HDDs I have errors when I copy big size files. (CRC calculation failed)
I try to use Windows Explorer and copy an 320 MB archive file to WD 3.5 IDE HDD. The copy process finished ok, but the archive was copied corrupt.
I start making more tests with two kama connect 2 adapters (mine and my friend's one) on other systems and other IDE 3.5 HDDs, and I get same result: With SATA HDDs and 2.5 IDE laptop HDDs everything is OK, but with 3.5 IDE HDDs big files (over 200-250 MB) are copied corrupt.

I want to know that this is an issue with big files on kama connect 2 3.5 IDE interface or just bad luck for both devices.

Thank you.
