Q1.What is the R/W speed of the RS-MMC and mini SD?
RS-MMC 2.4MB / 2.2MB
60x mini SD 9MB / 7.5MB
50X min SD 7.5MB / 6MB
Q2.Are memory cards used only on DSCs or DV players?
No. Memory cards can not only be used on DSC or DV players, but also on many other digital devices.
Q3.What is the difference between TSOP and WSOP packing?
TSOP and WSOP are two different types of packing of IC. TSOP is the most popular one, and 90% of ICs use this type of packing in the market whereas WSOP is a later technology than TSOP. However, IC is thinner and smaller with WSOP packing. The dimensions of IC are12mm x 17mm x 0.7mm by WSOP packing, which is 42% of usual ICs. So far, WSOP is treated as the main packing method in the near future.
Q4.What is the difference between a CF card and a Micro Drive?
Micro Drive is a memory card with built-in mini hard disk whereas CF card is a memory card with built-in Flash memory. Since the dimensions of the CF card and the Micro Driveare the same, both cards can be used on similar devices.
Q5.How much memory capacity is recommended?
It depends on the desired quality of the data or the conditions that the card is used for. For example, a 128MB memory card is able to have 85 high-quality photos (5 MEGA pixels), which is quite enough for most users. However, when the memory card is used during a trip, 512MB or higher may be needed. Therefore, users can choose the card according to their needs.
Q6.Where can I find information about the reading and writing speed of memory cards?
Please refer to the detailed description of each memory card.
Q7.How can I get the information onto the memory card if I am using a Notebook?
Generally speaking, users can use an additional card reader or a PCMCIA Adapter for reading information in the memory cards.
Q8.Is the SD card slot the same as the MMC card slot?
Yes, the dimension of SD card is similar to MMC card; therefore, the slots of both cards are also the same .
Q9.Are there any digital device (DSC/PDA/Card Reader) compatible with A-DATA memory card?
Please refer to the technical document at www.adata.com.tw
Q10.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 speaking, if users do not use the memory properly, problems might come up. If a problem occurs without any of these improper usage reasons, please contact A-DATA service department for help
Q11.Do the Flash disks have Zip function?
So far, A-DATA Flash disks don’t have this function.
Q13.I want to set the partition of my Flash disk, but when I finish the steps and re-plug in the Flash disk, the lock.exe can’t be clicked. What should I do?
Please take a look at the attached file for the details. Download
Q14.I have a 512MB Flash disk, but how come I can only see 498MB capacity usable at the most?
Windows systems use the binary system; therefore, 1MB = 1024KB. The Flash memory disk is decimal system based, which means 1MB = 1000KB. In other words, we have to check the capacity from byte numbers instead of MB number.
Q15.What is the R/W speed of the RB1?
R/W=10MB/8MB
Q16.Can I use the Flash disk to create a virtual disk?
Unfortunately, no Flash memory disks can support this function yet.
Q17.What can I do if I cannot get the Flash disk to work on Win ME?
First of all, please use the Windows Update. Secondly, install the USB port driver of the motherboard.
Q18.Why do I always get a “Memory Shortage” message when I paste files onto the Flash memory disk even when the total capacity of files do not exceed the capacity of the Flash memory disk?
This problem exists when the Flash memory is formatted by FAT16 format. With FAT16 format, users who try to copy and paste more that 255 files at one time may receive an error message. When this situation comes up, users can format the Flash disk with the FAT32 format to avoid this problem.
Q19.What is the difference between USB 1.0, USB 1.1, and USB 2.0?
USB 1.0, USB1.1, and USB2.0 are three different interfaces of USB port. USB 1.0 interface can transfer data at 1.5 Mbps/sec whereas USB1.1 interface can transfer at to 12Mbps/sec. The USB2.0 transfers at the highest speed of 480Mbps/sec.
Q20.Can I use any A-DATA Flash memory disk as a bootable one?
If users want to make a bootable Flash memory disk, make sure the computers you are using can support boot with USB Removable Disk (it can be seen in the BIOS settings). Users can then use the software in a CD or download the software from the A-DATA website http://www.adata.com.tw/adata_en/support.php?DriverType=driver to make the Flash disk a bootable one.
Q21.How can I find out the model of my Flash disk?
Q22.Can I use A-DATA Flash memory disk on Win95 or Win NT 4.0?
Unfortunately, these two operating systems do not support USB devices. In other words, it is not possible to use Flash memory disks on Win 95 or Win NT.
Q23.I tried to change the default setting of DDR400 to 2 2 2 5, and the computer keeps beep. What are the correct settings for DDR400?
We do not recommend users to change the SPD numbers. Unstable problems may be caused as a result of changes in SPD.
Q24.What is CL?
The full name of CL is CAS Latency, which pertains to the time of delay or preparation of the module. For example, CL 2 means that it takes two clocking time to read the data from the module. Overall, the price is higher if the CL is lower.
Q25.How can I find the drivers or software for A-DATA Flash memory disks?
Q26.How can I change the SPD numbers of the module?
We do not recommend users to change the SPD numbers. Unstable problems may be caused as a result of changes in SPD.
Q27.How can I plug the modules into the motherboard?
There is a specific feature on the motherboard that protect users from plugging in modules incorrectly. If you find it difficult to plug the module into the DIMM, please check to see whether the key on the module is in the same area of the key on the motherboard. Also, please turn the computer off when you want to plug the modules in or pull them out.
Q28.Can I clean the pins of module with cleanser?
No. We suggest you to use an eraser to clean the pins of the module.
Q29.Can I change the settings to force the module for better performance?
There is no need to change any settings. Unstable problems may be caused as a result of setting changes.
Q30.Can I use DDR333 with DDR400?
We suggest not using them together since the BIOS can go wrong during the booting when receiving different SPD numbers.
Q31.What is ECC?
The full name of ECC is Error Correcting Code, which means the module can detect the error and repair it itself. With ECC, the computer system can continue to function normally.
