||The CF Card in my DSC is full, but it fails when I place it in the Reader,and I get a request to format it instead.
The format of the CF Card in the DSC is not compatible with that in your PC. In this case do not format your card, just complete it with complimentary software.
||What can I do if my memory card is not recognized by the DSC, PDA, or Card Reader?
There are many possible reasons for this situation:
1. The DSC is suddenly turned off when data is being read or written.
2. The memory card is suddenly taken out when the DSC is reading or writing data.
3. Photos are taken when the battery low.
4. The memory card is passed through an X ray.
5. The memory is close to a magnetic device.
6. The memory card is suddenly taken out when the card reader is reading or writing data onto the card.
Generally , if users do not use the memory properly, problems might come up. If a problem occurs without any of these improper usage reasons, please issue a “Format” command on a PC by card reader. If the drive can't be “Format” please contact RITDATA service department for help(email@example.com).
To avoid the flash failure, please be notice the above situation.
||If your 150X SD 2GB is recognized as 1G byte after re-format,
please download this fix program and it will be recovered to 2G byte
This could cause by the device. For example, Palm PDA Tungsten support up to 2GB SD but Palm PDA Tungsten T3 only support up to 1GB SD.
||I put the CF card into the Card Reader, first it worked well, but later it no longer worked
So for in Card Readers and PDAs, this has occurred only when the card is pulled out imprudently while it is still working or there is a format problem.
If you plug in or unplug the card improperly, it will be disabled. Do not pull out the card before completion of data retrieval on your system while the DRAM memory is still working or the card will fail.
This is due to error in the file system which will take up some available flash memory. To solve it, just re-format.
||I have bought a Ritek CF Card and tested its compatibility, however it seems much slower than another card I bought later.
Controller, circuit design and flash memory will affect a CF card's speed. We have assured that all cards are compatible with the standard of the spec of the CFA, but we cannot assure that all have the same speed.
||What do 12X, 16X and 24X on CF Card labels mean?
Like CD-R, X stands for speed. 1X stands for 150Kbytes/Sec while 12X stands for 1.8 Mbytes/Sec.
Manufacturers calculate speed differently. In general, "Sustained write speed" is approximately 900KB~3.6MB or 6X~24X, "Sustained read speed" is 1.8MB~7.2MB or 12X~48X, and "the Weighted averages method" is 12MB~5.4MB or 8X~36X. Thus speed ranges differ quite a lot depending on the method of calculation.
Ritek considers calculating by "the sustained write speed" to be more accurate.
||The CF card worked well in the PDA but failed in the NB. Have both of them a CompactFlash interface? Why does it fail even if I re-format it?
Although CompactFlash is a standard interface, it is merely a storage medium. It will become non-compliant with applications due to the different formats under different OS.
Ritek Cards are formatted under PC OS before shipping, so that work without fail. Should your card be formatted under a specific PAD, it has to work under such environment. This situation is the same everywhere.
