63648 2002-07-19 23:29:00 How do you tell which is ATA 66 or 100 or UDMA or not at all? How many types are there? Could I have OS (XP) problems if I used the wrong cable?

Colour coded? Blue=m/b? grey=primary MAster? maybe?

CAble select = primary master at the end?

Cheers

Always a shaded area.

there are two types of cable - 40 wire and 80 wire . 40 wire I think restricts you to ata33, and 80wire lets you run the others . Using the wrong cable will just slow down data transfers - won't give OS problems .

the colour coding is just to tell you which plug to put into where - shouldn't actually make any difference if they go in the other way around - never has for me anyway .

I believe so .

63650 2002-07-20 03:51:00 There are three types . (I am assuming that CS is no longer used with the fast IDE 80 wire cables) .

If the drives are set for CS ("cable select", you must have a cable with one wire cut after the first drive connector (wire 20 from memory) . That is, there are 40 wires going from the motherboard connector to the first drive connector, and 39 wires between the drive connectors . I think that the convention is that same as that for floppies --- the connector at the end is for the first drive, the intermediate one for the second . If the device selection is between MA/SL, the connector order does not matter . There is a theoretical reason for using the very end connector for a single drive, but it "probably" wouldn't matter .

63651 2002-07-20 06:02:00 Cable select has been improved in the ATA66/100/133 standard (actually seems to work!). :) Now the master is the middle connector. BIFF (1)
