Hi,
I need to read from a CompactFlash card in an external card reader. I have been trying to followig the instructions found in another thread, but even though the device appears in the list of devices, it fails to be mounted. the messagge says something like "wrog block mount". I have also tryied with a differt device, replacing the multicard reader with a pendrive, but the outcome is the same. I quote here the instructions I followed:

Thread: how to cofigure USB flash drive?
wrangler Hi,
Can anyone give pointers or links which explain how to configure portable usb flash drives. I have mandrake 10.1

thanks,
Sen
db391 If you mean getting them to work, that means adding a line to your /etc/fstab:

Also mkdir /mnt/usb and KDE (or gnome) will add the USB (sda1) to the devices.
wrangler thanks for that but in: /dev/sda1 /mnt/usb1 vfat user,noauto,rw,sync,noexec 0 0 should it be sda1 or ...
rpz I have no experience of flash drives in Mandrake, but in Fedora, the drives appear under /dev/sdaN, where N is not constant (for example, right now my USB drive is /dev/sda4). I prefer to use hald to automount them when plugged in (they pop up on the desktop just like in winxp/osx). This daemon takes care of all the hassle with fstab lines. This is default in Fedora, in mandrake you might have to install it yourself.
LJSBrokken Anyone any idea why some flash drives work well, while others seem not to be recognised?
fstab line isCheers, Leon.

As anybody a clue to fix it?

change noauto to auto and there is a kde utility that will auto-mount them on the desktop, but i can't remember it's name offhand

Thank you very much for your reply.

I have successfully monted the drive not using your instructions, but throught the commandline, but this is only a partical victory since I wish to see the content of a compactflash card in a multicard reader and this doen't work. It works with my pendrive only. Do you have any clue how to fix it with the multicard reader. The model is Trust 725 usb 2 card reader/writer pro.

TI quote from the commmand line: [
root@localhost mnt]# mount /dev/sda1 /mnt/usb
mount: /dev/sda1 is not a valid block device
[root@localhost mnt]# mount /dev/sda /mnt/usb
[root@localhost mnt]# mount /dev/sda /mnt/usb
mount: /dev/sda already mounted or /mnt/usb busy
mount: according to mtab, /dev/sda is already mounted on /mnt/usb
]

Note that sda1 doesn't work, sda works (in the hardware list I also see sda, sdb, sdc sdd, according to 4 drive in the multicard reader when it is connected to the computer, only sda appears when the pendrive isconnected)

And this is the commandline when I try to read from the multicard reader, a compactflash card should be in the sda drive:

[
[root@localhost mnt]# mount /dev/sda /mnt/usb
mount: special device /dev/sda does not exist
[root@localhost mnt]#
]

The last few lines of fstab file now appears like this:

[
fstab
dev/hda2 /mnt/win_f ntfs umask=0,nls=iso8859-1,ro 0 0
none /proc proc defaults 0 0
/dev/hda7 swap swap defaults 0 0
/dev/sdb1 /mnt/removable auto umask=0,user,iocharset=iso8859-1,sync,kudzu,codepage=850,noauto,exec,users 0 0
]


Do you have any clue on how to make the card reader work?

Thank you
regards

Enrico

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.

In this case I have closed the original in Newbie because Hardware
