Problem:-I hav external usb harddrive,how can i make it detect from

message)
Are we discussing an actual USB hard drive, as this says, or a memory card reader acting like a hard drive, as the subject line says? If a hard drive, what does its partition table look like? In particular, is its sd*1 partition a valid filesystem type? If so, what is it (usbdevfs? unlikely vfat? more likely)?
Please be as specific as you can about the hardware involved.
Even i followed dha steps dat u replied for message(94020),i still cant able to detect my External USB hardrrive..frum Fedora core linux.
i did all trials, what i did iz: # /sbin/modprobe sg #/sbin/modprobe usb_storage
lsmod giving me da exact thing,as below: # /sbin/lsmod | grep sg sg 28513 0 scsi_mod 105360 4 usb_storage,sg,libata,sd_mod
Could we see this lsmod output unedited? (Without the pipe to grep, I mean.)
Also, in your logs, are you seeing a message something like this one:
kernel: Attached scsi disk sda at scsi1, channel 0, id 0, lun 0
Or, what does "more /proc/scsi/scsi" report as present?
If a drive is present at /dev/sda (or any sd*), what does fdisk report about its partition table?
pblm cums wher , it was showing like as below: # mount -t usbdevfs 0 /proc/bus/usb mount: 0 already mounted or /proc/bus/usb busy mount: according to mtab, usbdevfs is already mounted on /proc/bus/usb
If it is already mounted (as the last line says), then this is not a problem. You might tell us what /proc/bus/usb reports about the status of the USB bus.
# mount -t vfat /dev/sda1 /mnt/HD12 mount: /dev/sda1 is not a valid block device
I would expect this command to work (assuming a vfat filesystem is present at sda1). This response does usually mean that the device entry does not have a physical partition associated with it.
As u said, i tried with other scsi devices for mounting,,, but not worked out,, Wht i tried iz: sda,sda1-5, sdb, sdb1. i tried every possibilty....
Am I correct in inferring that you always got the same response ("is not a valid block device")? Or did something different happen in any of these attempts?
At this point, based on your report, it is hard to pin down where in the process of attaching this device your efforts have failed. If you respond with a more systematic report, I (or someone else here) may be able to offer a helpful suggestion. In addition to the specifics I've asked above, please mention or quote, as appropriate:
the output of "uname -a" (If you are using a kernel you compiled yourself, and not the stock Fedora version of that kernel, you need to mention that too.)
whether you have *any* other USB devices on this system (e.g., a keyboard or a mouse).
the specifics of the drive itself (make and model, and whether you have had it working in other contexts)
the output of "lspci -vv" that relates to the USB interface
Based on my own experience ... with USB flash drives, not hard drives ... the general approach you are taking is correct, at least as far as you have described it. So the problem is probably in some "unimportant" detail you've omitted.
