From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050302 Firefox/1.0.1 Fedora/1.0.1-1.3.2 Description of problem: I can mount my USB external disk drive with no problems under Linux. However, if I transfer a large amount of data (eg > 1 GB) then the hard drive becomes unusable and is then automatically unmounted from the system. After seraching on the internet I found that many people are experiencing the exact same problem: http://kerneltrap.org/node/3844 Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: Plug in external usb 2.0 disk Copy large files to it (eg contents of a DVD movie) Actual Results: After a period of time the drive becomes unusable and the copying of files cannot be completed. The hard drive sometimes gets automatically unmounted. Expected Results: Should be able to copy files to an external USB 2.0 disk. Additional info:
What version of the kernel is running? (uname -r)
I have used all 2.6 kernels and the same bug appears in all. I just tried with 2.6.11.5 compiled from source code and the bug is still there. The same problem with 2.6.9 and 2.6.10. It happens with all RPM versions of the kernel and the one distributed with fedora core 3.
if it happens with the upstream kernel too I'd suggest reporting this upstream to either the linux-usb-users list, and/or linux-kernel.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
This bug has been automatically closed as part of a mass update. It had been in NEEDINFO state since July 2005. If this bug still exists in current errata kernels, please reopen this bug. There are a large number of inactive bugs in the database, and this is the only way to purge them. Thank you.
