Hi.

I'm going crazy over this issue. I have a USB enclosure with a 120GB drive that has a ext3 and a NTFS partition. I can see both partitions and I can access them and I can also copy small files to the drive (at least around 3 MB) - but I can't copy large files to it (at least not over like 60 MB)!! I have tried several times but every time I get the same problem: the copy process hangs and I can't do anything on the drive until I restart the computer. I can't even unmount the device since the system says that it is busy. How can this be possible?!?

The enclosure is a USB 2.0 device. this is what lsusb says:

Bus 002 Device 005: ID 04b4:6830 Cypress Semiconductor Corp. USB-2.0 IDE Adapter
Bus 002 Device 001: ID 0000:0000


And this is what dmesg says right after I hook it up:
usb 2-1: new high speed USB device using ehci_hcd and address 8
usb 2-1: new device found, idVendor=04b4, idProduct=6830

Thanks for any help!!

Also while I'm still at it can somebody tell me if I can destroy the HD by doing trial and error "experiments" like trying to copy files and then pull the cable out in rage after the system hangs??? (... not that i'd do that... but in case someone else would - then it would be good to know...)
