There is something about this hard drive that i want to bring into notice to people in the forum who are more knowledgeable than me. Let me first specify my sys.
Impression 771AS (KX 133, 686A south bridge) motherboard with 4x AGP.
Award Modular bios v6.00PG
128mb Ram (kingston, pc 100 set at cas2, cycle time 8 ns, access time 6ns)
ATI 32 mb rage fury pro.
SAF SCSI 12x4x32 CDRW
Primary master: 20.4 GB UDMA66, 7200 maxtor
primary slave : 13 GB, UDMA66, 5400 seagate
secondary master: delta 12x DVD
seconday slave: I/O magic 56X cdrom
PCI modem
sound blaster live!
USB scanner and webcam and parallel printer etc.
OS win 2000
okay here is the probs. if i enable UDMA mode in bios bench mark test (dr hardware 2000) shows the hard drive read/write speed is as good as UDMA 66 hard drives. where as if i enable UDMA 66 the speed becomes much faster than a normal UDMA 66 hard drive (max read speed 23.3 mbps compared to 12.9 for UDMA 66 and max write speed 51.2 Mbps compred to 12.8 mbps for normal UDMA 66 drives). But the system becomes unstable and it hangs once in a while writing to Disk (not while trying to read). And if i reset the bios fails to detect both the hard drive. I have to power it down and then switch the power on in order to detect the hard drive by bios. Any idea what is going on here? i am sure some of you have definite answer to this.. and i don't think its a power supply problem because I have 300 w power supply..AMD approved and i checked with other power supply also same thing.
