Description of problem: ======================== system type : i386 / Compaq Presario V1039AP. OS : Fedora Core 5 Release. Kernel : Default Kernel that comes with FC5. Problem description: ====================== I have a complete iso collection of FC2 , FC3 , FC4 and FC5 [ Including RPMS,SRPMS] on my Local IDE HDD.Natuarally the overall size of this collection is very large.Recently i copied the whole folder of about 15GB to an external USB-HDD [ VFAT/FAT32 Filesystem ] once the whole stuff was copied and i tried few checksums i see that the ISO images copied to External HDD are actually changed.I burnt a few ISO images from my external HDD to CDROM and not to my surprise i see that those images were broken. I noticed one thing.While copying the Large folder to EXT-HDD the USB drive light would stop in between with out doing anything and my suspect here is the USB driver.there is some issue with I/O when it is doing in bulk. Version-Release number of selected component (if applicable): ============================================================== N/A [ FC5 default// out of intrest i tried this on my FC2,FC3,FC4;same issue follows ] How reproducible: ================= Steps to Reproduce: 1.Copy Large ISO image collections from Local IDE HDD [ EXT3 FS ] to an ExT HDD [ FAT32 FS ] 2.do a checksum of iamges copied to EXT HDD using either md5sum/sha1sum. 3.You can see the difference between checksums meaning copy was not perfect ; I have tried to copy files upto 500MB successfully.but with sizes like 15GB it fails. Actual results: ================== Try it yourself.If any doubts in above explanation contact me at akalexi312 Expected results: =================== I expect the CP to be perfect.something seems to be wrong.I doubt this to be the USB Driver for Linux.

This is not a usbutils userland problem. Assigning to kernel.
It may be a bug, but in 95% cases it's something related to a hardware malfunction (specifically, a bug in the enclosure firmware is the most likely culprit). At this point, I can only suggest replacing the enclosure with a unit of a different brand.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
