Hi
my /dev/sda is removed? what can I do to restore it? It used it for my cool disk (USB2 flash disk)

Thanks,
Mohammad

udev should create the device node when the module is inserted into the kernel. Is the module sd_mod? try (as root)

modprobe sd_mod

you might need to modeprobe usb-storage too

could you describe clearer?
I didn't get what you said.

another possibility to check is: under the Mandrake control center - system - services, if hotplug is not running it will not find your flashdrives on the fly. I am fiddling after kde 3.4 upgrade, found flashdrives did not appear when plugged in, went to Mandrake control center - system - services and found hotplug stopped and not checked to start at boot. Started it and plugged in flash drive, it now appears under /mnt/removable again.

This seems to be a frequent problem with Mandrake. I have it myself - am running MDK 10.1 CE. I have a Firewire CompactFlash card reader that shows up as sda1 ... when it shows up.

Happily, I have found a reliable way around this problem. By default, after startup, I have a /dev/sda, but no /dev/sda1. When I try to do the usual mount of sda1, I am told that special device /dev/sda1 doesn't exist. No other help. After lots of dickering around, I have discovered that I can reliably force Mandrake to create /dev/sda1 by putting my flash card into the reader, and then as root issuing:

mount -t auto /dev/sda /mnt/sda1

Note that I am attemting to mount the DEVICE (sda) rather than the partition (sda1). For whatever reason, although you get a failure message back from this (nonsensically saying that you must specify the file system type), it does result in Mandrake examining /dev/sda and creating /dev/sda1. After that you can mount it normally. This procedure works 100% of the time. I have now taken the above mount, plus a sleep of one second and then a normal mount command, and added the lot to a KDE menu item. Works like a charm!

Hope this helps.
