What is meant by ATA-33 and ATA-66 with respect to hard disks and which one will be recognized by Intel Mother board SE440BX-2?
ATA-33/66/100/133 are speeds at witch the hard drives pass information to each other and other drives CD/zip/ect. 33 denotes a speed of 33 megabytes per second max transfer rate. 66 Mbps and so on. The motherbroad will see both. but may not be able to transfer data at the speeds rated by the drives http://support.intel.com/support/motherboards/desktop/se440bx2/sb/cs-013633.htm When in doubt ASK INTEL. True they don't support everything indefinetly (sp) but they DO SUPPORT THIS BOARD... Answer = "Hell NO!" Below is an excerpt from the page link offerd here. Will my ATA-66 hard drive work on the Intel SE440BX-2 Motherboard? The IDE controller integrated into the Intel SE440BX-2 Motherboard supports Ultra DMA modes 0,1, and 2. Ultra DMA mode 2, also known as ATA-33 or Ultra DMA 33, is the highest transfer mode supported by the Intel SE440BX-2 Motherboard. The motherboard hardware cannot support the maximum transfer rate of the ATA-66 drives. ATA66 hard drives will only operate up to ATA-33 on the Intel SE440BX-2 Motherboard. Please refer to the Technical Product Specification and the Motherboard Specification Update for more complete details on the various transfer modes. I had to look it up myself as I upgraded this very board with a better chip. Bloody thing will run a 550MHz processor and can't pass ATA33
What else can I help you with?
Whats the difference between an ATA66 cable from an ATA33 cable?
the ATA66 cable simply transfers data faster than the ATA33 cable. So if you've gotta choose between the two go for the ATA66.
Can you use an ATA33 CD-R on a motherboard with IDE connection for ATA 66-100-133 if the motherboard is a Foxconn 648fx4mr-es?
In theory, yes. ATA 133 is backwards compatible all the way to ATA 33. However, if you have trouble, the most likely problem is that the motherboard bios needs an update. I had this problem on an ASUS MB. The CD drive would appear in the startup/BIOS and I could even boot to the CD-ROM drive to begin to install windows, but once the install got 2/3 done and windows loaded all its drivers, the CD drive would disappear as far as the operating system was concerned. If you are having a similar problem, go to the MB manufacturer's website and update your bios. WARNING - this can be very risky, since it is possible to kill a Motherboard by installing the wrong BIOS on it.
