Im running XPproSP1 on an Epox 8k3a+ with 512 pc400 corsair ram. Mobo has 2x
ide "normal" (IDE1 and 2, VIA 8233A) en 2x IDE RAID (IDE 3 and 4 in my story,
Highpoint 3.72).
Ide 1: WD 120 GB master <> Nec 2500a DVD-burner slave
Ide 2: Maxtor 40 GB master <> LiteOn 163d DVD-reader slave
Untill a few days ago I was running a RAID1 array on IDE 3 en 4, consisting of
2 Maxtor's 6Y120L0 discs. 1 disc on IDE3 and 1 on IDE4, both on cable select
and thus detected as masters. This worked fine.
I deleted this array in order to have more HD space (120 -> 240 gig). After
formatting both HDDs and partitioning them identically I realised there was
something wrong.
The writespeed on HDD(IDE)3 is between 35-40 mb/sec when I move/copy large
files from another HDD to it. When I try the same to HDD(IDE)4 the write speed
averages at 6 mb/sec, roughly 6 times slower. This is only a writespeed issue,
not readspeed, they both have the same proper readspeed.
My troubleshooting actions:
switched IDE3 and IDE4 including cables, NO RESULT, same HDD is still slow but
now on IDE3 instead of IDE4.
Maxtor knowledge base & FAQ: Used Powermax Diagnostic tool and WriteVerify tool
I did a full format on Powermax, writing 0’s to the entire disk surface and
then tested it fully and the disk passed flawlessly
I took out the fast HDD and tried with only the slow one on IDE3&4, No
difference.
Now it gets intresting:
I took out the 40GB Maxtor on IDE2 and put in the slow HDD (120gb Maxtor) as a
master on the secondary IDE and behold, the HDD’s writespeed is NOT slow
anymore and functioning totally normal with speeds upto 42 mb/second.
I am baffled by this, it must prove there’s nothing wrong with the drive (as
Powermax proved as well), switching IDE3&4 proves there is nothing wrong with
the IDE ports……
I spent 2 days and many hours on this issue allready, mainly on Dutch forums,
but nobody seems able to help me, so I am trying the international community
now.
