I recently installed a second hard drive (WD 120GB) on my new Dell Dimension 4550 (w/ XP home). The drive is installed as "slave" on primary with the original hard drive from Dell (WD 30GB) as "master" on primary (jumpers set to CS as required by Dell - by "slave" and "master" I'm referring to position on IDE cable). I used the original IDE cable from Dell with master connected to end and slave connected to middle. The installation went well except that I noticed transfer mode of slave set to PIO when checking Device Manager after installation. With advice from other forum I downloaded and installed the Intel Application Accelerator (IAA) version 2.3 and that increased the transfer mode of the slave up to UDMA-2. I cannot set the transfer mode above UDMA-2 for this second drive. The transfer mode of the master has always been UDMA-5.
The second hard drive is capable of UDMA-5 transfer mode and the IAA Report tab confirms this. Below is shown the pertinent report data for primary master and slave drives. I notice some differences between the master and slave drives report data (see Cable Type (Host), UDMA Timing Register, and Base Clock settings):
Primary Master Report Info:
UDMA Mode Support: 0 - 1 - 2 - 3 - 4 - 5
.
.
Default Transfer Mode: UDMA-5
Current Transfer Mode: UDMA-5
Transfer Mode Limit: No Limit
Cable Type (Device): 80 Conductor
Cable Type (Host): 80 Conductor
PIO PPE: Enabled
UDMA Control Register: Ultra DMA Mode Enabled
UDMA Timing Register: CT = 3 CLK / RP = 16 CLK
Base Clock: Ultra DMA 100 Timings
Primary Slave Report Info:
UDMA Mode Support: 0 - 1 - 2 - 3 - 4 - 5
.
.
Default Transfer Mode: UDMA-2
Current Transfer Mode: UDMA-2
Transfer Mode Limit: No Limit
Cable Type (Device): 80 Conductor
Cable Type (Host): 40 Conductor
PIO PPE: Enabled
UDMA Control Register: Ultra DMA Mode Enabled
UDMA Timing Register: CT = 2 CLK / RP = 4 CLK
Base Clock: Ultra DMA 33 Timings
Do I need a new IDE cable (instead of the original provided by Dell?) to obtain UDMA-5 transfer for second (slave) drive? I'm pretty sure it's 80 conductor type.
I don't understand the 40 conductor data for Host Cable Type on the Slave report. I also don't understand the UDMA Timing Register data or the Base Clock data. Are these setting that I could/should change manually?
Is it possible to have both hard drives in UDMA-5 transfer mode?
Any advice, experience, feedback, guesses, etc. would be appreciated. Thanks.
