The simple answer is yes you can. In saying that though, some technicians (myself included), like to steer clear of doing it this way. Main reason being, the cable can stretch a little too far.
So it is best using 2 different ide cables, one for your hard drives, the other for your cdroms etc.
Not forgetting to change the jumpers accordingly. Slave goes on the middle, master at the end of the cable.
No its not ATA is a interface standard not a type of hard drive the only difference between Ultra ATA and a diffrent inerface standard is that it can use the 80-conductor cable or serial ATA cable
ATA/ATAPI -4, ATA/ATAPI -5, ATA/ATAPI -6, ATA/ATAPI -7 (SATA)
A serial hard drive is the same as a SATA hard drive. SATA is Serial ATA, and PATA is Parallel ATA.
ATA/ATAPI-4,ATA/ATAPI-5,UltraATA,fast ATA-2,ultra DMA modes0-2, DMA/33,ULTRA ATA/66,ultraDMA/66 all use an 80-conductor hard drive cable,as well as a few more standards not listed.
ATA and IDE use the same interface type, so the answer is YES, you can put the a ATA and an IDE in the same computer.
IDE drives commonly use the ATA standard. ATA usually runs at ATA-33, ATA-66, ATA-100, and ATA-133. These run at 33 MB/s, 66 MB/s, 100 MB/s, and 133 MB/s respectively. Most modern IDE hard drives run at ATA-100 or ATA-133 while older If you have your hard drive on a 40-wire PATA cable and/or the PATA cable attached to your hard drive is also attached to your CD-ROM drive, your hard drive might be forced to run at ATA-33. For best performance, only use an 80-wire PATA cable and do not connect your optical drive with it.
A parallel ATA interface cable. The hard drive it is set as a master and the CD drive as a slave.
