Hi, Thanks for your answer. Here is my steps: - mkfs.ext3 /dev/sda1 - mount /dev/sda1 /mnt/usb - dd if=/dev/zero of=/mnt/usb/test_file bs=1M count=1025 ( the size is important) - sync - rm /mnt/usb/test_file Then many errors appears "Ext3-fs error ( device sda1): ext3_free_blocks_sb: bit already cleared for block xxxx" I tried to umount/mount the storage but its not working also. I tried to check the device before removing the file, not working also. Indeed with another usb key it's working... I'm using a kernel 2.6.23 The problem does NOT appear with mkfs.ext2 /dev/sda1 before What do you advise to do ?

I don't mean that it's an IO error or a bad block, but perhaps a behavioral problem with the flash; maybe not syncing properly before it's powered off, etc. If it only happens with some USB drives, I do not think it is an ext3 issue. Your original problem report may not have been totally clear so maybe I misunderstand. Can you show exactly what you did, and exactly what error messages you received, keeping in mind that any IO type errors that don't say "ext3" are also relevant? -Eric > BR > > -----Original Message----- From: Eric Sandeen > [mailto:sandeen@xxxxxxxxxx] Sent: vendredi 4 mars 2011 17:26 To: > Stephane Cerveau Cc: ext3-users@xxxxxxxxxx; Tristan Pateloup Subject: > Re: ext3_free_blocks_sb when removing a more than 1GB file > > On 3/4/11 9:45 AM, Stephane Cerveau wrote: >> Dear all, >> >> It seems that if I change the size of blocks to 2048 by mkfs.ext3 >> âb 2048 /dev/sda1, the problem does not appear. >> >> Is there a way to know by advance what is the best block size for >> an external device ? >> >> BR > > Sounds like a storage problem; not a filesystem problem, something to > do with the flash behaving badly. > > -Eric > > > __________ Information from ESET NOD32 Antivirus, version of virus > signature database 5925 (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 > __________ 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
