Well, either my original posting didn't get through, or there are no IDE experts out there... My original problem was that my ST1144A (125Mb IDE drive) wasn't recognized by my system. Now, when I entered the drive parameters into the CMOS config, I can use the drive...BUT The factory test paper that came with the drive says (among other things) Sectors/Track 44 36 30 So which one is it? Or is it laid out so there are more sectors on the outside, and less on the inside radius (ie 3 zones) ? I entered 30 Sec/Track in the config table, and get 109Mb formatted capacity. No, Disk Manager software didn't come with the drive (shame on California Microchip). So, do IDE drives come with a driver of some sort? How come there's no controller bios on IDE interfaces? This makes IDE not as flexible as, say, SCSI, where you can throw in a cheap $35 controller card (that has its own bios!!!) and it can reside painlessly with other MFM or RLL drives. Any comments out there?...

I have a ST1144A IDE hard drive installed on my system. Reading through News some reported that they are 125M drives, others 130M. I have formated my drive to 119M How do I get it to 130 or 125M? What are the CMOS parameters to use. I like to get extra 10M or 5M on my drive.

there are two sets of translate parameters commonly being used. 1024x14x17 will give you 125 megs 1001x15x17 will give you 130 megs -- +--------------------------------------+ | Brent Mosbrook KC6MWK | | mosbrook@beach.csulb.edu | +--------------------------------------+

Francis : Your discrepancy in size is probably due to the formatted and unformatted capacity of the drive. Realize that MS-DOS is not the only operating system out there, while IBM machines can run any one of a number of operating systems. A Novell File Server will format the drive to a different data capacity, so will some variant of UNIX. You probably have formatted the drive out to the correct size for your operating system. If not, check to see how many partitions you have on the drive, if they all really exist, and if your system is seeing all of them, not just one...

I formatted mine to 125 Meg by setting it up in my AMI BIOS configuration as 1001 cyls, 17 sec/tk, 15 heads, with both WPCom and LZone at 1002. AMI reports a 125 Meg drive, SI reports 127, and Seagates says I'll receive 130 Meg with this configuration. I receive about 130,000,000 bytes free with this config.. ___________________________________________________ Scott K.
