 Posted: Sun Nov 13, 2005 9:13 pm Post subject: mounting USB Flash disk on PC with SATA hdd |
 |
|
I used to mount my Flash disk on /dev/sda and my usb mp3 player on /dev/sda1. That was when I had IDE (PATA) hard drive.
I moved my system to a new SATA harddrive which mounts on /dev/sda, which is obviously in conflict with the USB flash disks.
Do you have an idea how I should mount the USB Flash disk now? I would really appreciate some hint...
dmesg | tail after plugging in the Flash key:
| Code: |
usb 1-1.1: default language 0x0409
usb 1-1.1: new device strings: Mfr=1, Product=4, SerialNumber=0
usb 1-1.1: Product: USB Mass Storage Device
usb 1-1.1: Manufacturer: USB 2.0 Flash Disk
usb 1-1.1: hotplug
usb 1-1.1: adding 1-1.1:1.0 (config #1, interface 0)
usb 1-1.1:1.0: hotplug
midi 1-1.1:1.0: usb_probe_interface
midi 1-1.1:1.0: usb_probe_interface - got id
midi: probe of 1-1.1:1.0 failed with error -5

dmesg | tail after plugging in the usb flash mp3 mplayer:
| Code: |

usb 2-1: SerialNumber: 23DE7394D6190E07

use sdb just like you would with a normal hard drive with hda and hdb

Nice tip, it has one defect though.. There's no /dev/sdb in my system, only /dev/sdaX
Notice the last line of the dmesg output: midi: probe of 1-1.1:1.0 failed with error -5
something failed....
It seems that no device in /dev was created for the flash disk :-/ |

you can probably just create it in /dev give it a dir to mount to in /mnt add the line to fstab and then just mount it.

I've got the mp3 player to work after reverting to the older SCSI-style driver as suggested in Gentoo kernel 2.6 migration guide:
| Code: |
Device Drivers --->
Block devices --->
< > Low Performance USB Block driver
|
It then appears on /dev/uba1
However the problem with the normal Flash disk still remains :-/ |

Ok, I'll try that too, but perhaps tomorrow... it's getting late here. Thanks |

Well the nodes in /dev are special files which are either character special files, which support byte-level I/O, or block special files, which support I/O in larger units. Disk partitions are represented by both character special and block special files. So it seems to me that the best idea is to copy one like sda and rename it sdb and give it a mount point in /mnt

That did not help either. Btw, copying the file is not a good idea since it starts to copy the contents of the device.
The special files can be created using mknod program.
So for example you go:
| Code: |
/ $ cd /dev
/dev $ mknod sdb b 8 16
/dev $ mknod sdb1 b 8 17
/dev $ mknod sdc b 8 32
/dev $ mknod sdc1 b 8 33
|
to create sdb, sdb1, sdc, sdc1. The b stands for block device, the numbers are minor and major numbers. 8 is for SCSI device and the second number is for the actual device. You can find the numbers in /usr/src/linux/Documentation/devices.txt
I think the problem is that neither of the drivers is able to assign (and create) a special device for my USB Flash key... So, maybe next kernel release will help...I hope...
(Now I use 2.6.13-r3) |

i have a better idea. Try vanilla which is 2.6.14.2 and see if that sorts it out. If it does post a bug report with gentoo sources.
