External HDD is unmounted

[shvydky]

Hi All,

Can anybody help me:

My router can't use 2TB External HDD with following messages in system log:
Jan 1 02:03:13 kernel: usb 1-1.1: reset high speed USB device using ehci_hcd and address 3
Jan 1 02:03:14 kernel: usb 1-1.1: reset high speed USB device using ehci_hcd and address 3

Jan 1 02:03:15 kernel: printk: 11 messages suppressed.
Jan 1 02:03:15 kernel: Buffer I/O error on device sdb1, logical block 0

HDD is powered with external power.

Operation Mode:Wireless router
Firmware Version:3.0.0.4.260

I have no other device to check that it is working now but I have successfully used my router as media server with .242 firmware and 8Gb flash-stick.

Sounds like potentially either filesystem corruption or a bad sector. Plug the HDD to your PC and do a full surface scan through chkdsk.

Thank you for your idea but this is first thing that wsa done by me. I have checked and defragmented HDD using Windows 7 laptop.
I did not win.

More info:
- Small 40Gb HDD is working normally;
- I have checked 2TB HDD with chkdsk but problem still exists.

Please, help me

Make sure you do a full surface scan, not just a filesystem scan. In a command prompt, assuming disk is on letter Z:

chkdsk z: /f /r

RMerlin,
Thanks, but I am sure:

G:\>chkdsk g: /f /r
The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process. Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) y
Volume dismounted. All opened handles to this volume are now invalid.
Volume label is HITACHI.
