HTH, M Yeah it's something to do with the scsi/sata drivers now handling IDE devices, it caused me some grief at first because I used to hot-swap my laptop drives with a KDE utility which stopped working (I since found the /sys/class tree which I can use to add and remove controllers). But my desktop still has /dev/hd* devices and it's running the exact same Ubuntu kernel as my lappy. I don't really understand but as long as it works I'm happy :-) Regards, Tom -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
[ubuntu-uk] IDE Flash Card Readers - Recommendations
Hi Folks Hands up, I'm confused! I'm trying to find myself a Card REader that will specifically take CF and SD cards that I can connect to my IDE that supports hot, err thingy that allows you to take the cards in and out without powering the PC down. Don't think this feature is supported on Linux yet, but my PC is dual boot and this reader is at the moment to be used with the M$ installation, but I don't want to get hardware that's not going to be Linux compatible. Does anyone have any recommendations? I primarily want IDE as I intend to hard mount it into one of the drive bays of my home PC. I've looked at Linux Emporium, Amazon, Dabs, LinEx and a few others that I came across, and although I found a lot of readers, none give those reassuring words of Linux / Unix compatible. Any insights or recommendations appreciated. Cheers E -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

Re: [ubuntu-uk] IDE Flash Card Readers - Recommendations
Hi Lee Thanks. OK, next question is how do laptops with in built card readers do it? I admit I'm not sure if they are connected to the USB, PCI or IDE but presuming it's the USB is there anything I need to look out for when looking for a card reader, apart from what I've already mentioned? The ability to boot from a CF card is not on my immiediate horizon, although to use it as a place to run apps from may well be.

Re: [ubuntu-uk] IDE Flash Card Readers - Recommendations
Hi, My laptop (Thinkpad) has a CompactFlash slot which is essentially a PC-card slot shrunk down. It's on the PCI bus and when you insert a CF card it emulates an IDE device. It's hot swappable, but so are the IDE controllers for the hard drives in the laptop and in the docking station which allows me to pop out a hard drive or optical drive after unmounting it. However, recent versions of Ubuntu have shown all my laptop drives, including CF memory cards, as SCSI devices (/dev/sd* as opposed to /dev/hd*). My desktop dies a horrible death if I try to do the same with one of its hard drives, which are still shown as traditional /dev/hd* devices. Hope this helps shed some light. I'm no expert but I reckon a USB reader would be your best bet for a desktop machine, as Lee said most modern motherboards will boot from a USB mass storage device.

The ability to boot from a CF card is not on my immiediate horizon, although to use it as a place to run apps from may well be. E Laptop hardware is law unto itself, I've seen USB card readers, weird IDE bridges, PCMCIA bridges, you name it... The issue here is that that they are built to be hotswap-able, the IBM Thinkpad Bays that can take floppy drives, harddrives, optical drives or batteries are an excellent example of this... they may be IDE (and then some), but they are built to be hotswap-able, and have hardware, bios and OS driver support to be able to do this. Most standard motherboards don't, basically to keep the cost down... When was the last time anyone here felt the need to hotswap a drive out a a running PC? -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
