CBM Hoja de datos ( Datasheet PDF ) – USB Flash Disk Controller

The JF boots other computers OK. So if we remove the uncertainty of the USB ram size returned by the device and the data it holds in it’s flash memory, what remains must be an inconsistency between the USB devices in terms of what data they return when asked by the BIOS for Mode Sense, Read Capacity, Inquiry, etc.

I believe it is the other way around, some controllers can recognise different BIOSes and behave accordingly.

Posted 18 January – There is no “undo”, unless you backup best: To ensure absolute compatibility, the triple MBR preparation could be applied.

This design corresponds to a Harddisk, concerning the Boot Records. Maybe you find it useful, that no one else knows, how to proceed. Remember me This is not recommended for shared computers. An empty fresh formatted filesystem is easily to relocate. Not only Lexar can change from removable to fixed.

You currently have javascript disabled. Shifting the image around is not going to reveal anything new. To point it out clearly: To get the same drive Floppy style, MBR got hidden by just shifting each access to sectors by 32 sectors upwards. It’s output has nothing to do with the issue. Some more data on them: You datashest ID chips with ChipGenius. Each new BIOS changed the rules. I’m far from saying, that my used method works for anyone else but me resp.


Community Forum Software by IP. BIOS rules see Prologue. Does Grub4Dos really assign fd0 or fd0,0 to it??? Posted 07 September – IMHO the size of the whole stick not the partition plays an important role.

Posted 09 February – The Tool Box to share with you: My Way to success: I bet, someone did it anyway. So if you don’t use first primary partition for booting, you ddatasheet have to adapt the device name fd0,0; fd0, Sticks contain different data in their sectors. Steve shows some essential aspects, how to cope with a non-booting “bootable” USB stick.

Does someone have a Clik! Don’t use U3 as these are known to be non-standard. After all they are not dumb sticks: Posted 03 February – Unfortunately the criteria are not foreseeable.

Then try them both on all systems. It also works on a legacy floppy as regular PBR I created it for that purpose more than a decade ago.

For reference, my 3. That is why I am very keen to find out what the difference is between the two hence we are left with looking at the SCSI command responses that we get from the USB controllers. Wouldn’t you agree with my conclusion? If you access them through driver software, you won’t see that they are organized like harddisks, because you only see the logical drive through the driver.


This is more or less a sophistic approach to me, not a practical. You come to a conclusion that the controller is the important thing but with no proof Reliability was comparable to legacy Floppies keyword for ZIP: So there was no need to ever format a ZIP diskette as eatasheet. This will datssheet that the contents and physical drive size are not an influence on it’s bootability.

Sounds like you were having fun! This may interest you: Maybe the results of your tests reveal some important secrets of UFD booting.

In a wider sense, all these mentioned legacy magnetic storage media might be called “Superfloppies”, since they had nearly or exactly the physical dimensions, look and handling of legacy Floppy diskettes.
