It happens when I copy or make operations (zipping or ckecksum calculations)
on large files (i.e. 500 MB or more).
Similar issues look to be very common, and there are thousands internet
pages about it.
However I didn't succeed to find any relevant information concerning my
specific trouble.
Two HDs (40 MB Maxtor, ATA133 plus an adapter, 80 GB Lacie 2.5" mobile)
both are NTFS formated and present the same anomaly on two different
computers (a recent HP portable running XP and an home made Asus A7N8Xdeluxe
running Win 2000 pro SP4).
On the home made, I've on a regular basis, two other HDs, USB mounted but
FAT32 formated. One has two 95 GB partitions (SATA), one with two 120GB
partitions (PATA). Eventually other FAT32 disks are also connected to the
computer, with the same brand of USB to IDE adapters. No issues.
From the tons of information I read, the issues concern as well Win2000 as
XP.
I'm really focussing on the association of the USB -and- the NTFS -and- the
huge files. Consequently, I excluded the adapters and the disks.
* The "Write to cache enabled" option is greyed in the "disk properties" for
the USB disks.
* In the performance options of the system properties, "optimize the
performance for:", I disabled "the applications" and ticked "background
services". I didn't have the usual error ultil the _last_ big file,
resulting into the complete loss of the partition table of the failing disk.
* No UDMA parameters seem to be adjustable for the USB mounted disks. If
there are, please, tell me where.
For the moment, I'm investigating on the registry, what keys & parameters
should I look for ?
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management ?
SystemPages ?
IoPageLockLimit ?
Since I don't know the effects I prefer not to modify them, waiting for
clues.
Thanks in advance
