usb drive could not format ext4

[bernd]

I tried use an old IDE-HD (60GB) with an USB-Case.
When formatting ext4, I always got error message "trouble with superblocks".
Therefore I couldnt mount the drive.
When I formated FAT32 with Windows, I could use the drive on my Raspberry.
I changed to another HD and may things, always the same: ext234 didnt work,
FAT32 only when formatted with Windows PC.

After this I found another USB-Case with another chipset.
This worked great. All drives and all FS could be formatted.

So I think it was a problem with this special chipset of the first USB-IDE converter!
