I conisider myself very technically competent, but this problem has me completely stumped. I can't find any info about it in a search of Google or of this forum. Here's my complete system info:
Windows XP Home (with SP 1)
Aspire X-Superalien case with the Aspire 500w PS
MSI 865PE NEO2-FIS2R Mobo
Intel P4 2.8C Northwood (800MHz FSB)
2Gb Corsair TwinX 3200 RAM (4 X 512) (Page File turned off)
MSI GeForceFX 5900XT Video Card
Turtle Beach Santa Cruz Sound Card
LiteOn 52X24X52 CDRW
Hitachi 40X DVD ROM
WD 80Gb EIDE HD
IBM 30 Gb EIDE HD
Miscrosoft Wireless Desktop Elite Mouse & KB
DELL 2001FP Monitor
And here's what I just changed yesterday that started the problem:
I installed a new Hitachi 160Gb SATA HD, but only as additional storage, not as part of a RAID setup. I connected it to the onboard Promise SATA controller. It installed and formatted just fine and shows up correctly in Windows Explorer. I have already moved about 30Gb of files to it. The files transfered quickly as expected.
But here's the problem: Each time I start the computer, then open Windows Explorer, there's a REALLY LONG delay expanding any of the folders for that new drive (and ONLY that drive - the other drives are not affected). The delay is always at least 30 seconds but it's usually closer to 2 minutes!! Once each folder has been expanded once, it will open quickly from then on, even if I close Windows Explorer then come back later. But if I reboot, I have the same delay expanding the folders again.
Things I've tried or verified:
1. Hitachi Drive Fitness Test veries the drive is OK.
2. All BIOS settings are correct, and I've even experimented with some of them just to be sure.
3. The computer is free of viruses or adware.
4. There are no corrupt files on the new drive.
5. All connections are correct and tight. I also tried another cable.
6. The Promise driver is loaded and working.
7. The drive has been defragged.
8. I've turned off the "Indexing Service".
9. DMA is enabled.
10. I also used the ICH5 SATA controller and had the same problem.
I hope one of you has a bright idea that I've missed.
