:) I'm not removing the key during the test. Yes "umount/mount/rm", "umount/fsck/mount/rm" and "rm" give the same error... I have several keys from the same brand, model and I have the same issue. When I said, a different key, it was a different brand. At the end, it seems that ext2 is working fine! So maybe a problem in ext3 in 2.6.23 kernel ?!? I had a try on 2.6.32_27, I did not succeed to reproduce the issue. Do you know when ext3 is supposed to be stable ?

Try a much newer kernel, first of all, to see if it's a known, fixed bug. But since it works on another usb key, I still tend to blame the hardware. "bit already cleared" makes it sound like it is reading zeros when it should not be. -Eric > BR > > Stephane. __________ Information from ESET NOD32 Antivirus, version of virus signature database 5926 (20110304) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 5926 (20110304) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
