Only if they contain a filesystem, otherwise as long as you aren't doing anything with the card at the time you yank it, everything should happen automagically on semirecent Debian installs. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Right. However, also like USB devices, if the PCMCIA card is or contains a mobile storage device, to gain access to the storage on the device it has to be mounted. Likewise, before such a PCMCIA card, like USB storage devices, is removed, it should be unmounted in the same manner. Right. As it happens, I still have a PCMCIA adapter for CF cards, which is what was used to connect CF cards to laptops before the days of USB ports on laptops. So I put a CF card in it and inserted it into a PCMCIA slot. pcccardctl ident returned: product info: HITACHI, FLASH, 5.0, manfid: 0x0007, 0x function: 4 (fixed disk) Dmesg however told me much more.

By creating directory /media/pccfcard and running mount -t vfat /dev/hde1 /media/pccfcard I had complete access to the cf card. I then added an appropriate line to /etc/fstab, which I will test after the next time I boot my laptop. I would doublecheck the fstab(5) manpage to make sure you don't try to automount any filesystem that you don't intend to have connected each and every time the machine boots. http://ursine.ca/cgi-bin/dwww?type=runmanlocation=fstab/5 It is interesting that the adapter manufacturer is identified as Hitachi; whereas the adapter is labelled Sandisk. That's actually not that unusual. Much (most?) hardware is manufactured by one company, but distributed, labelled and sold as another brand. I also noticed that pccardctl includes the commands insert and eject. Since the cards can be hot inserted and removed, I wonder why have these two commands. Scripts that are automatically called when a device is inserted or ejected.

Not usually, but I suppose what type of card it is. I have a modem PCMCIA card which I just release whenever I feel like it. But if its some sort of storage device (if there is such a thing) then you *may* lose data. Also, how do you actually unmount one? -- Chris. == Don't forget to check that your /etc/apt/sources.lst entries point to etch and not testing, otherwise you may end up with a broken system once etch goes stable. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Ken Heard [EMAIL PROTECTED]: Thanks everyone for the replies. If I understand them correctly, the situation is as follows: Very good, however: Sure enough, I found a directory called /dev/hde1. By creating directory /media/pccfcard and running mount -t vfat /dev/hde1 /media/pccfcard I had complete access to the cf card. I then added an appropriate line to /etc/fstab, which I will test after the next time I boot my laptop. No need to wait. Very few things in Unix/Linux require a reboot to take effect. From a prompt: mount /media/pccfcard should work right away, or tell you why it didn't. I also noticed that pccardctl includes the commands insert and eject. Since the cards can be hot inserted and removed, I wonder why have these two commands. So the hotplug/udev systems could do it for you. cardctl showed up a long time before hotplug and udev did. -- Any technology distinguishable from magic is insufficiently advanced.

NAME mount - mount a file system ... as to PC cards they are managed by the cardctl or pccardctl commands (depending on how recent your kernel is). see man cardctl or man pccardctl depending on how recent your kernel is. I happen to have a portable CD-ROM burner attached to my laptop via a PC card. If in need to check the current status of that PC card (in slot) 1 I could issue a: # pccardctl status 1 5V 16-bit PC Card function 0: [ready] Now, after inserting a data CD in this peripheral in order to access its contents I would have to mount the file system: # mount -t iso9660 /dev/cdrw0 /mnt/cdrw0 I can then cd - no pun intended - to /mnt/cdrw0 and apart from the fact that the files are necessarily read-only.. I can pretty much process its contents as I would my home directory. IOW, it is as if I had plugged the iso file system that lives on the CD-ROM into an available slot of my running file system, thereby giving myself and other users of the system access to its contents. If on the other hand I had inserted an audio CD in the peripheral I would not need to issue a mount command to listen to it. And if I did try to mount issue a mount command against the audio CD, I would get an error informing me that the medium does not contain a file system. To try and clarify further, I also have a PC network card in the other pcmcia slot of this laptop and clearly there would be no sense in trying to mount that card.
