I have been trying to access an SD card using my 5 in 1 no name card reader. The reader it's self is plugged into a usb header on my motherboard and I know this has been done correctly as I've used on windows on a different partition.
The device doesn't appear to be showing up in /dev however I do have listed sde, sdf, sdg, sdh which I imagine has something to do with the device but they never show a partition on them (e.g. sde1).
Thank you in advance for any help.

posting dmesg, lsusb and other relevant logs could prove much more helpful

I went to copy across the lsusb log to this thread and saw something interesting and after a bit of googling found all I had to do was to run
hdparm -z [device]
To reread the partition device and all was good. A very 'newbieish' mistake I know but that's why it's posted here.
Thank you for your help any way.

I have the same problem as original poster. No sdX1 partition even after hdparm ...
Anyone has an idea please?

I don't know if this will help but if you have an external USB card reader, unplug it.
As root, type "tail -f /var/log/messages.log" and hit enter
Now plug in your card reader and watch the terminal window to see if it's recognized and if the system sets it up for you. This will give you lots of clues for where to look for the problem.

plug it in and do a 'dmesg | tail' - 9 times out of 10 and it will show up ...

I know how to check logs, but it is no help.

I know how to check logs, but it is no help.
1) reboot
2) insert card
3) dmesg | egrep 'sd.1' (note: you will find your sda1 there, but there should also be your card)

Thank you for trying to help, but please, read the firs post here carefully.
There are sdc,sdd,sde and sdf objects created, but no sdc1, sdd1, sde1, sdf1.
If they were there, I would not be having any issue.

For the record, my internal card reader shows up as /dev/mspblk0.
You can also run partprobe (part of the parted package) to get the kernel to re-read partition tables. Not sure if that's different than hdparm -z though.

Raqua, are you not interested in getting help? You claim you know how to check logs, but you never provide the information in these logs. You only claim that no device node was created in /dev. That is entirely unrelated to checking logs. And "it is not help" does not mean anything. Tell us which logs you checked and what you observed. I.e. post all the new logged information you get when connecting and disconnecting the reader.

For my comment, i'm assuming that you are using flash media formatted by a device rather than you as a linux user.
I'm also assuming that the system is recognizing that a card has been inserted into the reader.
Many devices that use flash media do not create partitions on the cards that they use. Rather they use the whole card, This will present the card itself as not having any partitions upon it. Since you are providing no data for me to work with other than what you say [which is not the same as a log file], I can only guess as to what to tell you to do.
Try running # fdisk -l /dev/* [where * is the location of your card after the system sees it.]
a dmesg or some other sort of output would be greatly helpful,
Hardware is like a parachute.... works best when open.

Sorry if my posts appeared somehow inappropriate, it was not meant to be like that. I just had a feeling that perbh did not really read the first post.
I was about to insert all the logs here, but now my cardreader started working. Must have changed with new kernel or some updates in the meantime.
Thank you all for your help though.

With all due respect - the first post wasn't even _yours_ - you hijacked this thread!

I don't think that saying "I have the same problem" is hijacking the thread.
But I appreciate your effort while trying to help.
