Questions on disk performance
HI..
I am still having some trouble with my system.
1 ghz AMD, 256 mb ram, 30 gb disk and 6 gb disk, savage4/32mb video card, 56k modem,
cdrom,cd-rw etc.
System will lock up for no apparent reason. No error messages. I do use Adobe Premier 6 for video editing and it locks all the time, but that may be for other reasons.
I recently ran across www.pcpitstop.com and ran the analysis they do on the system on-line.
Before, all the disk drives were set for "PIO" that has been changed to IDE.
The analysis reports the system is fine, except for "uncached" disk performance which is reported at 0.41 for both disks. They say it should be running at 3.9x for this system.
I have no idea what could be killing my disk performance, and/or if this could be a reason for my 'lockups'.
Any ideas out there?
Thanks,
Dave

In addition :
I would recommend that you download a diagnostic disk from your harddrive manufacturer's url. This will tell you right off where you are at and if
you can recover from it. It may be under warranty, the hard drives are usually covered for three years and you can make out the RMA on their site
also. Depending on the manufacturer of the hard drive, you can download diagnostic utilities from their sites to check the drives.

It a drive is flakey, this could be the cause.
Also check the BOS to see what PIO mode the drives are using and if it is set for maximum.
You may need to make a change there.
I hope this helps !

BIOS not BOS, my fingers are ahead of my brain or something like that.

Well, interesting results.
I had already updated the VIA chip set to no avail/
I downloaded the diag programs from Maxtor(c drive) and WD ( d drive)
The maxtor software would not even recognize hte C drive as a Maxtor drive (which it is).
The WD diags recognized both drives and identified them, then ran diags on both drives and reported they were working correctly.
This is really the strangest PC I have had in 10 years. When you restart it from the Start menu, it will run scan disk every time and if I try to skip scan disk, it just recycles and does it again. Sometimes I have to go through the boot process 4 or 5 times to gt it up.
I can assure you I will never but another AMD system.
So, any more ideas?

OK for scandisk -
In the C:\msdos.sys file - Use 0 not 1 !
After you have opened the file in notepad look for the line that says AUTOSCAN=1.
this is a hidden/system - read - only so fix the attributes first
from dos
attrib -s -h -r msdos.sys

Scandisk problem at bootup
Check for winboot.* on the root of your "C:\" drive (either sys or ini). If you do have one of these files, edit it and see if Autoscan=1 also in there.

More info :
Change the value of 'AutoScan=' to:
AutoScan=0 : Scandisk is Disabled
AutoScan=1 : Scandisk Prompts First
AutoScan=2 : Scandisk Runs Automatically
Changes will take place on the next reboot.

My system only locked up when the hard disk or DVD was thrashing about. Once I diabled DMA access it was fine and I have not noticed any significant decrease in performance.
Hope this helps.
