Subject: Problems with USB disk

Hi,

I'm having problems with a new 500 GB USB disk. It works, but sometimes I
get these in dmesg:


usb 1-3: reset high speed USB device using ehci_hcd and address 2
usb 5-1: USB disconnect, address 2
drivers/usb/class/usblp.c: usblp0: removed
sd 0:0:0:0: Device not ready: <6>: Sense Key : 0x2 [current]
: ASC=0x4 ASCQ=0x2
end_request: I/O error, dev sda, sector 254148215
sd 0:0:0:0: Device not ready: <6>: Sense Key : 0x2 [current]
: ASC=0x4 ASCQ=0x2
end_request: I/O error, dev sda, sector 252434023
EXT3-fs error (device sda1): ext3_find_entry: reading directory #15761836
offset 0


There's also a printer connected. This is on a pci/usb2 card. When the above
happens, I get I/O errors. When I mount the drive next, there are errors
and often missing files. Quite annoying!

Kernel is 2.6.21

What's going on?


Thanks,
Niels

You have a low voltage issue, or a bad cable. The device is
electronically disconnecting itself. Try using a externally-powered
hub, or a new cable.

It has its own power supply. All cables are new and plugged in securely.

Thank you for your answer,

I am seeing a similar problem with 2.6.22 and 2.6.23-* kernels with my 60G
iPod Video, works fine with 2.6.18 kernel though.

I see the external drive becoming read-only, although I haven't checked
the dmesg for the events, since other things in my system generate a
bunch of output I have to wade through.

New cable, separate power, doesn't do it under 2.6.20-* Fedora or
2.6.21.x kernel.org kernels.

I'll check the dmesg next time it happens, but I doubt a kernel version
change would heal the hardware issues you mention.

(no need to CC me)

So far I'm seeing this:

- On 2.6.21 I mount the drive. After a while it spins down, and when I then
unmount it, an error pops up in dmesg.

- On 2.6.18 I can't provoke the same error. The drive doesn't appear to spin
down. I don't know if the data corruption from 2.6.21 occurs with regular
use.

There are a number of other factor I need to eliminate on my system, but
that's it so far. CONFIG_USB_SUSPEND is not set on either kernel.

OK, on a vanilla 2.6.18.8 I also have this problem, with both the pci/usb2
card, and the usb1 on the board. I listen to music from the drive, and
after some time (10-20 minutes or so), it freaks out:

=========
sd 1:0:0:0: Device not ready: <6>: Current: sense key=0x2
ASC=0x4 ASCQ=0x2
end_request: I/O error, dev sda, sector 126693711
sd 1:0:0:0: Device not ready: <6>: Current: sense key=0x2
ASC=0x4 ASCQ=0x2
end_request: I/O error, dev sda, sector 126693711
sd 1:0:0:0: Device not ready: <6>: Current: sense key=0x2
ASC=0x4 ASCQ=0x2
end_request: I/O error, dev sda, sector 126693711
=========

Will updating to 2.6.23 and turning off autosuspend explicitly help? Will
putting the disk on a powered hub help?
