    Hello forum.

    Originally I was interested if these 266x CFs really work with declared speed on CF to ide adapters. Since You make that clear for me I was thinking of making an RAID 0 array with four 8 GB 266x CFs.

    Can someone (Miitsi / Machinist) please report results in HD Tach of two CFs in RAID 0 array.

    Only got this one Transcend 266x. So I RAID an ExtremeIV with the Transcend, and ended up with:



    which was just a bit disappointing, as the Transcend by itself was:

It is great for booting, it can format NTFS, create RAID, hibernate works, and it is faster than the Extreme IV. ...
    well it seem's you've had great succes using transcends cards. I am currently testing Debian/Ubuntu on CF in my tabletpc (Toshiba M200) with two SanDisk Extreme IV 2GB Cards (for testing) in an Addonics Dual CF-IDE Adapter.
    As it stands now i am unable to boot my laptop from the Extreme IV card in any possible configuration (only one, master, slave) as the computer hangs itself before loading grub. it's seems it tries to find the mbr but doesn't succeed (cpu fan kicks in and hdd light is constantly on)....
    However i can boot from an an old SanDisk Ultra II 1GB card. it's even possible to boot Linux on the Extreme IV if grub is installed on the Ultra II, the Ultra II is inserted as Master and the Extreme IV as Slave. I know that even dual Extreme IV works, but then i have to boot from Network.

    My conclusion (after reading this thread) that my tabletpc bios has some serious problems with "removable" type cfs.

    - But are Ultra II cards fixed type? (And if no one knows : is there a way to obtain the info from the cf?)
    - you mention a "fixed disk tool". Is this a tool to set a cf's typ to fixed? if so, where can one obtain this tool?
    - about transcend's cards: is there a difference between the consumer 266x and the industrial "fixed" card regarrding type? i couldn't find speed ratings for the industrial cards, can you share how fast they are?

    i know it's quite a bunch of questions but i'd be really nice if you could answer :-)

    [Edit] i can boot from the Extreme IV cfs in another pc so it's definitively the bios...

    So the tablet PC BIOS does identify the Extreme IV during POST? Have you tried copying everything from the UltraII to the ExtremeIV (including boot sectors)? Laptop BIOS are generally more difficult with these kinds of issues, they aren't really designed for accomodating CF. However, It is really odd if the CF card is detected, yet it doesn't boot. Not sure if this is related to removable/fixed compatibility. You selected IDE hard drive as opposed to CF in CF-IDE adapter in the Debian install?

    to answer those questions,
    - the UltraII is removable by default from manufacturer
    - the fixed disk tool sets to either fixed or removable, but SanDisk will no longer give it to you unless you are an OEM (they will ask you a lot of information for confirmation).
    - the industrial is detected as UDMA4, they say its 45x, it gets a little bit less than 20MB/s on hd tach. However, its great for booting and has 2m program/erase cycles.

    As this is a laptop bios there is no POST output. However inside Bios setup it identifies that an ide drive is connected. however the bois hides all relevant info (as connection-mode, hdd-id, etc. (and gives no way to force those settings)). It's just seems as if the cf does not respond the way the bios expects...

    Yes. however it does not work. oddly enough booting this cf in an normal pc works as expected (and the original cf works too). i tried it even with dd ...

    Yes i did a standard IDE install (first time i installed debian :-) )

    so it might not be a fixed/removable problem... a pity sandisk keeps the tool to them.

    thanks for your answers... their very much appreciated
    i guess i will try one of transcends 266x (or industrial) type cf's and hope it works

    Machinist.....excellent work on all this.

    I have been laying out my plan for my car pc and have been thinking most on what to do with the drives. I like the idea of CF at least for the boot drive.

    Would this be a good way to set it up. I am thinking of taking say an 8GB CF and putting the OS and apps (Navigation,front end,ect...) and using a 2.5" seagate momentus for the swap file and any storage (music,video,ect..) This should limit the writes to the boot drive. Would this not be a better way to do it? I need to use a 2.5" for storage since I have over 100GB of music alone, not to mention video and anything else. I dont see any CF out there with that kind of storage, and im not paying 1k for a SSD.

    Or should I just stick with a couple 2.5" drives and axe the CF. I would like the ability to have Internet and Email so I would have to figure out how to get those to write from the other drive........

    What say you,

    The CF + laptop drive is exactly what I have planned. I have a 4 gig CF that I'm working on, which is more than enough to install my C drive, even with RoadRunner, full Streets & Trips, and all the other utilities. I have a 120 gig Seagate Momentus for music and video files. I don't need a swap file, even with just 512 megs of ram. I figure the less it reads and writes to the disk, the better.

    I think you're right about that. Using a fast CF as the OS drive saves time on booting and opening applications, its makes a good difference when you're on the road. But in my opinion, this only applies if you use one that is fast enough. Even if a slower CF is able to boot into the OS faster than a normal hard drive, general usage such as loading programs or sometimes even simple things like clicking the start menu, dragging and dropping files might be suffer, then you start feeling the limitations of the CF.

    Although the board I am going to use is sata, so is that still going to be a problem? The cards I was looking at are the Transcend like the one you suggest or the Sandisk 5000 which is an industrial grade CF. I assume either would be sufficient to do all task needed? I will be using XP pro. Also havent heard anything on the UDMA6, any clues when we will see those?
