Slow hard drive transfer rates

I have two Maxtor 40GB drives, one as primary master, the other as secondary master. I back up all my music files from the main drive to the second one, but I've been getting transfer rates of only 1 MB/sec (45 minutes for 3GB). The drives are ATA 100; 7200 rpm. Why so slow?
just wondering why you didn't daisy chain your hdds; i.e., one as master, one as slave.

that's my setup and i get excellent preformance.
that is extremely slow, i would think there is a connection problem there, mine are on IDE0, and they transfer 60GB back and forth in around 30-40 min.


First make sure your bios is set up properly. I would set everything at auto if possible (With relation to the drive setups) Alternatively make sure LBA is enabled & make sure you are set up in Mode 4. Your idea of using seperate busses is a good one but you do not mention if there are other drives such as CDRom or DVD hooked up with them on the bus. If no, then you should get maximum throughput on IDE 0 & IDE 1. I run (usually) 6 drives in my system and even on my External ACOM I get much higher speeds than you are getting. The type of files you are trying to transfer also make a big difference. If you transfer a lot I would recommend you get a shareware utility called "PC Opus" in my humble opinion it is possibly the best file transfer utility ever written. It also does a variety of othe tasks as well. Just type PC Opus into google & you will find sites where it is available. You might also want to try setting your Bios to Optimal or Default & see if that helps. One other item that has the ability to slow down transfer rates is Viruses. I would Recommend Norton 2002 You can download a free 30 day trial at www.symantec.com if you don't already have it.

Best of Luck to you!

Also, run a defrag program and if you have an intel based chipset mobo (i.e., 840, 845), download and install the Intel Application Accelerator - really improves hd performance if installed properly.
