Sorry for the delay responding to this thread. Whilst linux users' computers are immune to viruses, our bodies are not.

I had this problem before, but it's not the case today :-( fdisk has no access to the /dev/sda device. Frederic and Konstantin... I have *EXACTLY* the same situation, and I figured out what was causing it, and I came up with with a workaround; I wouldn't call it a perfect solution. - My old, emergency backup machine is a 1999 Dell PIII, 450 mhz, with 128 megs of RAM, and USB 1.1 hardware. According to dmesg, the ehci_hcd code aborts at bootup, and only the ohci_hcd code runs. All my USB1 and USB2 devices run OK. Mind you, at USB 1.1 speeds, maybe I should say they *CRAWL* OK. The auto option for filesystem type works OK in both the mount command and in /etc/fstab. I could get away with an fstab entry like... /dev/sdb1 /mnt/external auto noauto,user,noatime,notail 0 0 and simply mount /mnt/external, regardless of what I hooked up to the USB port. - My relatively new AMD64 (in 32-bit mode) has USB2 hardware. I built both ohci_ocd ehci_ocd into the kernel. I experienced the following symptoms... - USB1 devices were totally flakey, sometimes they would show up as /dev/sdb1, and sometimes they wouldn't. When it didin't show up... So you have to do fdisk /dev/sdb, then quit, then the /dev/sdb1 is magically available for mounting. would usually work, but not always. - USB2 devices would show up OK, and run at USB2 speeds, but auto would *NOT* work as a filesystem type with either /etc/fstab or the mount command After a lot of screwing around I came up with the following workaround. - build ohci_hcd into the kernel - build ehci_hcd as a module. Do *NOT* auto-load the ehci_hcd module. - write local udev rules to generate symlinks for my USB devices. /etc/fstab has entries that mount the symlinks, and those entries specify the filesystem type. I use msdos for my camera's memory cards, vfat for my mp3 player, and reiserfs for my backup drives. Run in USB1.1 mode most of the time. When I'm backing up my hard drive to a USB2 drive, and I want the extra speed, I run the commands modprobe ehci_ocd udevstart ...before I plug in the backup drive. When I'm finished, and have removed the backup drive, I run the commands rmmod ehci_ocd udevstart ...and I'm back to where I was before. It's not perfect, but it works. -- Walter Dnes [EMAIL PROTECTED] In linux /sbin/init is Job #1 My musings on technology and security at http://tech_sec.blog.ca -- gentoo-user@gentoo.org mailing list

Never give up.
Try hexdump on the device above:
hexdump -C /dev/disk/by-id/usb-Generic_USB_Flash_Drive
Here is an example of mine, having partition table with PT boot code at offset
0 and FAT16 boot sector at offset 4000hex with msdos/windows boot code (it
was formatted in W2k). If you don't see any of the like anywhere on the disk,
it is possibly encrypted on-chip or broken. You may even see some windows
virus on your PT and/or fat boot instead of boot code. If you have no valid
partition (since your fdisk fails on it) but able to find your FAT somewhere
on the disk, it is possible to reconstruct, but I advise to dd whole disk to
file before. To seek the boot sector of the volume, look for the signature 55
aa hex at end of sector, just like mine are at offsets 01fe-01ff (pt)
41fe-41ff (fat boot). Sector size is 512==200hex.

Port should provide up to 500mA, while many notebooks are very weak at usb power and do not keep up the standard. To eliminate the first one, you should seek for the computer (or maybe an external usb hub) which will work with that chip. To eliminate the power issue on your equipment, you can try to measure consumption at the +5V with some prepared usb cable or even try to feed the device from an external power source. You will need laboratory equipment to do it (A regulated laboratory power supply with current limitation). Ask some electronics engineer. As a first aid, try an external usb hub with it's own power supply. 1G flash chips require a lot of power to operate, and not having enough is consistent with your symptoms of no media. -- Petr -- gentoo-user@gentoo.org mailing list

Re: [gentoo-user] No /dev/sda1 with Klingston usb disk. Wrong lsusb output.
Hey Fred. Is the USB key in question formatted with a FAT partition by chance? If so, you may need to load the vfat module as root, or, build vfat (Windows FAT32) filesystem support into your kernel, or perhaps, add an entry for the USB key in your /etc/fstab if you already have vfat support. http://gentoo-wiki.com/HOWTO_USB_Mass_Storage_Device Sláinte! -Jeff Frédéric Grosshans wrote: I've a problem with a recently bought usb disk:there is a /dev/sda node but no /dev/sda1 .

Hi Jeff Le lundi 17 avril 2006 à 10:52 -0400, Jeff a écrit : Is the USB key in question formatted with a FAT partition by chance? I think, if it was a format problem, I would see a /dev/sda1 node, but wouldn't be able to mount it. I don't even see that /dev/sda1 , and fdisk has no access to /dev/sda (to reformat the disk) If so, you may need to load the vfat module as root, or, build vfat (Windows FAT32) filesystem support into your kernel, or perhaps, add an entry for the USB key in your /etc/fstab if you already have vfat support. Thanks, but I already have vfat selected in kernel (not as module) and a fstab entry. Furthermore, the same USB disk has worked once before (with small files). If only it was such a stupid mistake !

Re: [gentoo-user] No /dev/sda1 with Klingston usb disk. Wrong lsusb output.
I noticed similar behavior on the externally connected usb storage devices. On the example of the SD card reader, when you insert the card, /dev/sdb appears, but not the actual partition (/dev/sdb1) So you have to do fdisk /dev/sdb, then quit, then the /dev/sdb1 is magically available for mounting. Think it is an issue with udev. kos -- Respectfully, Konstantin V.

Re: [gentoo-user] No /dev/sda1 with Klingston usb disk. Wrong lsusb output.
Good. According to processed events, there is a raw disk dedected properly but no partition processed. If you still do not see /dev/sda, try to look for your disk at folowing locations: /dev/disk/by-id/usb-*something* and /dev/disk/by-id/usb-*something*-part1 or /dev/disk/by-path/pci-*something*-usb-*something*-scsi-*something* and /dev/disk/by-path/pci-*something*-usb-*something*-scsi-*something*-part1 or /dev/disk/by-uuid/*something* If you can see your disk but do not see the *-part1 there, then no proper filesystem is found, however you can apply fdisk -l on that path of the raw device instead of /dev/sda and you will see what's wrong with your filesystem. But if you can see *-part1 there, you can just mount it instead of /dev/sda1. Beware you see all other disks in that machine as well in those locations. -- Petr -- gentoo-user@gentoo.org mailing list

I had this problem before, but it's not the case today :-( fdisk has no access to the /dev/sda device. Think it is an issue with udev. No, it's a problem with your kernel. You need to check the option File systems --- Partition Types --- [*] PC BIOS (MSDOS partition tables) support in make menuconfig and you won't need to fdisk to make /dev/sdb1 appear.
