unable to mount USB hard disk


i am unable to mount my new 100GB USB hard disk on my Debian Lenny box. However, i could mount this hard disk on the other Debian Lenny box without any problem. Basically, when i connect my USB hard disk to the system, a continuous beep sound is coming. pls help me in resolving the problem.

Hi dmsreddy, Welcome to lq. This continuous beep, is this a motherboard error, or post code? Is this happening after you've booted and then plug in the device, or is the device plugged in during boot? Does the system remain stable or is this beep a kernel panic? What does lsusb and dmesg say?
Good luck. ;-)

Good luck. ;-)
The output of dmesg is as follows:

usb 4-4: new high speed USB device using ehci_hcd and address 6
usb 4-4: configuration #1 chosen from 1 choice
scsi3 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 6

usb 4-4: reset high speed USB device using ehci_hcd and address 6
scsi 3:0:0:0: scsi: Device offlined - not ready after error recovery

The output of lsusb is as follows:

Bus 003 Device 002: ID 046d:c001 Logitech, Inc. N48/M-BB48 [FirstMouse Plus]
Bus 003 Device 001: ID 0000:0000

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

Nevertheless the beep from USB hard disk continues when I connect the same to the system.

Thanking you,

dmsreddy

P.S.: I had successfully connected this external USB disk on the different system with Debian Linux Etch/Lenny.

What is the file system on the drive? Have you tried a different cable?
Good luck. ;-)

Out of 100GB USB External HDD, I had created fat32 partition of 20GB. I have not used any different cable other than the one supplied along with the HDD.

What kernel version are you running? What happens if you boot with the drive already plugged in?
Good luck. ;-)

I hope that you would be able to offer some suggestion based on the above information.

P.S.: I am able to use USB pendrives (1GB) on my system and I have not used USB pendrive when I plugged in external USB hard disk to the system.

I'm seeing some references (googling) to a problem with either the hardware or the kernel. Some work arounds I've seen are saying to remove and reinsert the ehci_hcd module. I'm guessing the problem is with the kernel since the device works with another system. There are some kernel config options in this thread. Another route to take would be to compare the kernel config files for the system that works and the current one.

Does this drive have it's own power source or does it run strictly from the usb port?
Good luck. ;-)

This drive does not have its own power source.

That could be part of the problem as well. If you have access to a powered hub, you could try that. I've had problems with usb devices with multiple OS's that have power problems.
Good luck. ;-)

As suggested by you, I removed ehci_hcd module from the kernel and connected the USB external HDD to the system. It was detected by the kernel as 100GB disk. I was able to add/delete partitions from it. However, I was not able to write anything to the disk or mount the disk.

What does fdisk -l say about it?
Good luck. ;-)
