Hard Disc UDMA mode 66 or 100

[Guest]

Hi,

RE: Maxtor’s DiamondMax Plus 60 (5T030H3)

Is there any way of confirming which UDMA mode the hard disc is in at
the moment (66 or 100 MB/s)?

My Computer Spec.
Processor: AMD Athlon 900 MHz
Installed Memory: 512MB SDRAM
Microsoft Windows 2000 Professional
Service Pack 4 (plus all the latest updates).


Maxtor provide a utility program called 66to100.exe
Now the documentation says that it will change the UDMA mode of the hard
disc from 66 to 100 and this will increase the burst speed to a maximum
of 100 MB/s.

Now I have had my system for a number of years and can not remember if I
ever used this utility on my system.

I ran a benchmark program called HDTECH (version 3.0.1.0) and it
reported a sustained transfer rate of 31.9 MB/s with bursts of up to
74.0 MB/s.

This would suggest that the utility has been applied to the disc drive
but I do not know how reliable this benchmark program is however, and
was wondering if I ran the 66to100.exe program would it make any
improvement to my transfer rate.

I am nervous about running such programs because if it goes wrong then I
have a ‘dead’ system!

Thanks.

Since HDtach shows burst rates of well over 66 MB/s your HD is clearly in
100 (or better) MB/s mode. You're done.
