Storage Solutions need help in connecting 2 hdd
- Thread starter MAGNeT
- Start date
magnet said:i m looking for guide or site which hav detail image pictures of how 2 connect 2 hdd...i havent tried or done this b4....and most of the things i hav learned frm my own xperiments...i dont rely on h/wenggr...so plz do help me...
SATA or PATA ??
magnet said:pata right now?????/for sata is it different???can i connect 1 sata and 1 pata drive too???if mobo supports sata
for PATA read this page...

SATA drives do not have jumpers for master and slave but each drive connects seperately via its own data cable to a SATA drive header on the mother boad, normally mother boards have 2 SATA drive headers and some newer and higher end board will have more headers which can also handle RAID.
check out a SATA drive data cable here..

I run a SATA as well as a PATA drive without any problems.... I have WinXP installed on both drives and I can boot to either drive by selecting the first boot drive in the BIOS.
Do you have your mother boards manual ? these manuals normally have a lot of this information.... if you dont have the manual then check on the mother boards manufacturers site for a downloadable copy of the manual.
hey i guess.....in hard disk i have to place the jumper settings as masters for primary...slave for secondary disk...........m i right??????
and then connect the coonducter primary to secondary to mobo...then another shd go directly only to optical drives...........
correct me if i m wrong?????
also why is sata faster than pata.........we learned mor bits can b transfered in parallel connection than in serial....if u hav simple lang reply than do reply..else ill relly on another frnd of mine(google)

You need Jumper for primary Master and for some HDD there is no need of jumper for slave.For slave refer guide on HDD or manual.
Both HDD's are connected to same (Master) cable , coz there is lott difference between transfer rates of optical drives and HDD's.
And for SATA(Serial ATA) and PATA(Parallel ATA) , its the same reason , USB(Universal Serial Bus) is faster than Parallel cables.
Reason's are
Processing Overhead
First, remember that data is stored and retrieved one track at a time, one bit at a time. We talk about bytes for convenience, but a byte is just a line of eight bits in a row, and ultimately, we have to process each bit separately.
Thus, before we can send a byte in parallel to a disk drive, we have to get those eight bits and line them up, funneling each to a different wire. When we've done all the processing and moving to get them all ready, we fire off that byte.
At the other end of the cable, when the drive receives the bits, it must go through the reverse process to convert that byte back into a serial bit stream so the disk drive write heads can write it to the disk.
To visualize this another way, think about what's almost precisely the reverse processâ€â€converting parallel to serial for transmission and back again. This is what happens in sending Morse code over a telegraph line. The message starts out as written words (think parallel) on a sheet of paper. A processor (i.e., the operator's brain) has to convert each letter into a series of dots and dashes (serial) and then send these over the wire.
At the receiving end, another processor has to listen to these serial dots and dashes, then convert them back into letters and words. A lot of overhead is required because the transmission medium doesn't match the original input or desired output.
Signal Skewing
As a signal travels over a wire or an integrated circuit trace, imperfections in the wires or integrated circuit-pad drivers can slow down some bits.
In a parallel connection, the eight bits that leave at the same time don't arrive at the other end at the same time; some will get there later than others. This is called skew. To deal with this, the receiving end has to synchronize itself with the transmitter and must wait until all bits have arrived. The sequence of processing is this: read, wait, latch, wait for clock signal, transmit.
The more wires there are and the longer the distance they span, the greater the skew and the higher the delay. This delay limits the effective clock rate as well as the length and number of parallel lines that are feasible to use.
Crosstalk
The fact that parallel wires are physically bundled means that one signal can sometimes "imprint" itself on the wire next to it. As long as the signals are distinct, this doesn't cause problems. But as bits get closer together, signal strength attenuates over distance (especially at higher frequencies), and spurious reflections accumulate because of intermediate connectors. As a result, the possibility for error grows significantly, and the disk controller may not be able to differentiate between a one and a zero. Extra processing is needed to prevent that.
Serial buses avoid this by modifying signals at the time of transmittal to compensate for such loss. In a serial topology, all the transmission paths are well controlled with minimum variability, which allows serial transmission to run reliably at significantly higher frequencies than parallel designs.
