Has anyone else had an issue transferring large files to external usb drives ? What seems to be happening is it will float right along until it gets to the last couple of megs and then just sit there for a few minutes. The larger the file the longer it sits there. I am having the problem with both an external 1 gig usb HDD and two separate thumb drives. All of which have been verified as functional and fast under other systems. All of the drives are formatted in NTFS for portability in the field. I also do not believe this to be a hardware issue as it does it on my daily driver as well as my laptop.

This is the kernel I am running

Linux 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux

All the drives were automounted.

Any words from the wise would be strongly appreciated.

How about booting to a live cd and making more tests? Your OS and a few others might help for clues.

Also controller OHCI or what.
