Are the newer/faster ATA-100 drives backwards compatible? I have a 2 year old computer that is running out of disk space. I'm not quite ready to replace the whole thing. Are Ultra DMA/100 compatible with the original spec? Specifically a 60GB IBM Deskstar 60GXP. TIA, Jeffrey -- I don't do Windows and I don't come to work before nine. -- Johnny Paycheck

yes, they are, but you might have the get a bios update in order to be able to use the disk. i recently picked up a western digital 40gb hd with an ata-100 interface and it works fine on my 440bx motherboard (ata-33 interface) after i upgraded my bios. --trey

Whoops, forgot all about that. If your board can't see more than 2, 8, or 20GB, don't use an overlay program. You can use LILO to specify the disk geometry, thus bypassing the need for a disk overlay and the hassles they cause. ===== -- -=|JP|=- Hit me! - http://www.xanga.com/cowboydren/ Jon Pennington | Debian 2.3 -o) cowboydren @ yahoo . com | Auto Enthusiast /\\ Kansas City, MO, USA | ICQ UIN 69 67 29 31 _\_V __________________________________________________ Do You Yahoo!?

TIA, Jeffrey
They should be compatible. Please avoid the confusion between the PCI bus ( which comes in 33Mhz and 66Mhz flavors, the latter being reserved to high-end servers) and the IDE bus, which comes in many flavors, 33Mbits, 66Mbits, 100Mbits and 133Mbits (soon). Therefore the 60GB IBM Deskstar 60GXP (100Mbits) should work at 33Mbits. BUT I bougth this disk and tried to put it in my 3 years old system, and it didn't work. My solution was to buy a Promise IDE controller (a PCI card) and plug the drive into this controller and not into the controller of my motherboard. Then I can do hardware RAID 0 or 1, take full advantage of the fastest interface (100Mbits) and stuff my system with 8 IDE devices (that's a file server). Best regards, David Garnier

Hardware RAID with a Promise controller ???? If it's one of the Fastracks, it's as far from being hardware RAID as possible. And please show me an IDE drive that really does 100MBits. AFAIK the fastest drives are somewhere between ATA33 and ATA66. So even the fastest disk available wouldn't be slowed much when run on an ATA33 adaptor! This is the same old game of making interfaces faster and faster without the disks catching up.

Actually, even most of the Maxtor disks can support 35 MBytes/second sustained transfers (280 Mbps), which is certainly far from saturating a 33 MHz PCI bus, but can certainly over-run an Fast Ethernet connection. When you consider that some drives like the Western Digital WD100BB-SE have an 8 MByte buffer, if you are dealing with small files, then having ATA-100 on a fast bus can give you some outstanding performance, especially when tuned properly. - Herman Philipp Thomas wrote:

Yes. Fully capable of running in PIO Modes 0 through four and all lower ATA modes (excluding ATA133 ;). ===== -- -=|JP|=- Hit me! - http://www.xanga.com/cowboydren/ Jon Pennington | Debian 2.3 -o) cowboydren @ yahoo . com | Auto Enthusiast /\\ Kansas City, MO, USA | ICQ UIN 69 67 29 31 _\_V __________________________________________________ Do You Yahoo!?
