HDD -Master/slave

  [DELETED] 09:31 20 Nov 2003

Hello again, This is not a problem I have, but my nephew ,mistakenly thinks I know something about computers.

My question is:- Can the hard drive be set to slave and the CD rom to master,on the same IDE cable? If so how will the drive letters be assigned. In other words ,will the HDD which is the slave still be "C" drive. Thanks J

Hi ribo. I think it depends on the BIOS. The ASUS A7V8X-X, for example, gives a choice of first boot device that includes selecting which hard drive is the bootable one. Other motherboards only give a choice of hard drive, floppy drive, cd-rom etc. personally, I only ever put the bootable hard drive as primary master, so I don't know how the BIOS handles the drive letter allocation.

The bios should handled it ok, I think(?). BUT why not set the h/d as master and the cd rom as slave. In which case you are bound to get the h/d as C. If he is concerned about speed of the bootable drive with two devices on the saame ide cable he'll not notice any difference setting it as slave. I am curios as to why he wouild want to do it this way. Making the h/d master, which normally contains much more data would allow him to access the data quicker.

The hard disk (presumably with an OS installed) would be the first primary partition marked as active, and will always be C.

Well, as I said this is my nephews computer,apparantly he built it, ot rtied to, ended up with a problem and took it to a computer store. He got it back last night and they told him that they had put the HDD as slave and the CD Rom(he only has 1) as the master. They said "because with his set up it worked better"!!!

I again predded the button, before I was finished. to continue...Last night he installed XP Home (New install) and he says he now has the drive letters assigned as A floppy D CD Rom and E his hard drive!!. He cannot change the drive letter of the hdd , I presume because he is using it when trying to do so. Has this clarified anything? J

He really shouldn't have the hard drive and CD on the same IDE cable even.

Does he have any other IDE devices in the system?

Not that I know of. J

Then I suggest you (he) get a second cable - put the hard drive as the Master on the primary cable - and the Cd as the Master or Slave on the secondary cable. This is the preferred route - there shouldn't be any problems in any system with this setup.

Thank you all for your help. I shall pass on all your comments to my nephew. I do not really know all the details. Thanks again. J
