I'm trying to repair USB disk (64GB) originally formatted with ext4 I read the USB stick on Windows via some kind of windows ext4 driver now I can not open it on Linux box.
e2fsck -a /dev/sdb1 64gb: recovering journal (just stays there and does nothing). when I unplug it I get: e2fsck: No such file or directory while trying to re-open 64gb 64gb: ********** WARNING: Filesystem still has errors ********** (dmesg): usb-storage 8-1:1.0: USB Mass Storage device detected [1175553.773966] scsi host8: usb-storage 8-1:1.0 [1175554.790598] scsi 8:0:0:0: Direct-Access Verbatim STORE N GO 5.00 PQ: 0 ANSI: 6 [1175554.791142] sd 8:0:0:0: Attached scsi generic sg2 type 0 [1175558.511554] sd 8:0:0:0: [sdb] 120933888 512-byte logical blocks: (61.9 GB/57.7 GiB) [1175558.511720] sd 8:0:0:0: [sdb] Write Protect is off [1175558.511722] sd 8:0:0:0: [sdb] Mode Sense: 23 00 00 00 [1175558.511890] sd 8:0:0:0: [sdb] No Caching mode page found [1175558.511891] sd 8:0:0:0: [sdb] Assuming drive cache: write through [1175558.514906] sdb: sdb1 [1175558.515986] sd 8:0:0:0: [sdb] Attached SCSI removable disk [1176008.633223] usb 8-1: USB disconnect, device number 46 [1176008.641063] sd 8:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [1176008.641069] sd 8:0:0:0: [sdb] tag#0 CDB: Write(10) 2a 00 01 38 08 00 00 00 08 00 [1176008.641073] blk_update_request: I/O error, dev sdb, sector 20449280 [1176008.641076] Buffer I/O error on dev sdb1, logical block 2555904, lost async page write [1176008.641113] sd 8:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [1176008.641116] sd 8:0:0:0: [sdb] tag#0 CDB: Write(10) 2a 00 01 3c 08 00 00 00 08 00 [1176008.641118] blk_update_request: I/O error, dev sdb, sector 20711424 [1176008.641120] Buffer I/O error on dev sdb1, logical block 2588672, lost async page write [1176008.651400] VFS: Dirty inode writeback failed for block device sdb1 (err=-5). -- Thelma
