| Upgrading Computer Memory (DDR2-667) Guest 23:48:08 |
| | Greetings!
I have recently purchased a new Fujitsu-Siemens desktop computer. The
model name is SCALEO P-011. The price-to-feature ratio was very
impressive, and the my previous experience with this brand has been
nothing less than excellent.
However, one area where this PC is lacking is memory. It has only
512MB's of memory, and I would need at least 1GB. Unfortunately, I'm
very confused about what type of memory I should acquire. The
motherborad specification states the following:
* 4 DDRII DIMM memory slots (supports up to 4GB memory)
* Supports dual channel DDR II 667/533/400 DIMM
* Supports 1.8V DDR II DIMM
All was fine so far. I figured I should get myself a DDR2-667 1GB
memory kit. But when I went onling shopping for memory kits, I found
matters a little bit confusing. For example, Newegg.com has two
subcategories for DDR2-667 memory: PC5300, and PC5400. Furthermore, all
the gold, extreme, and whatever special edition memory kits are more
abundant in different categories. Like DDR2-800 or somesuch.
So, my questions are:
1. What's the difference between PC5300 and PC5400 DDR2 memory?
2. With the motherboard specifications I gave above, would the
motherboard be able to run memory modules of higer clock rates? For
example, DDR2-675, DDR2-800, etc.
3. Could anyone suggest a decent memory kit what would work on my
configuration, and preferablly offered by Amazon.com?
Many thanks in advance.

| PC3000 David 10:30:07 |
| | What happens if you have a hard disk which spins erratically, or the
heads are making clicking noises, or maybe everything seems fine but
the disk is just not recognized by the PC or any other tool? Since you
don't have access to the disk you may conclude that it is due to the
controller board failure or some mechanical or physical damage, and
whatever you try to do to fix the drive is then driven simply by your
intuition because you have no information about the status of a drive
that is simply not recognized by your utilities.
But help is at hand, because the PC3000 is a unique tool that can
communicate with the drive in such situations by using vendor specific
commands to switch the drive into kernel mode - the one that is used by
the manufacturer to provide read/write access to the firmware on the
controller board and firmware modules, such as Microcode Overlays, HDD
Configuration Tables, Defects Tables, SMART Attributes, Security
Subsystem, Adaptives, etc., stored at the disk service area
(maintenance track) at negative cylinders. When the drive is not
recognized by the PC, it basically means that the HDD cannot boot up
properly due to electrical failure, mechanical/physical damage or
corruption of the firmware modules on the controller or the disk
service area (maintenance track). By using PC3000 you can diagnose the
drive and determine exactly what is causing the failure. Furthermore,
in our experience more than 50% of such failures (and for some
particular HDD models over 90%) are due to firmware related problems
that can be resolved using PC3000. You can simply reload firmware
modules onto the damaged drive or just use one of the PC3000 built-in
fixes available for the most common failures of the particular HDD
model, such as Fujitsu MPG's firmware damage, Maxtor's G-List/P-List
corruption (e.g. 'Maxtor N40P' and 'Maxtor Athena' family), Western
Digital's S.M.A.R.T. counters overflow and others.
PC3000 supports 3.5" ATA/SATA Hard Disk Drives from the following
manufacturers :- Maxtor/Quantum, Seagate, Western Digital, Fujitsu,
IBM/Hitachi, Samsung, Conner, HP, Kalok, Teac, Daeyoung, and Xebec.

| Vaio, no restore disks, new OS, no mouse... Brandon 12:31:03 |
| | Alright, friend has a vaio pcv-rx450 that the OS went belly up on. Recovery
disks present a "critical error" at 12% every time, they are pretty
scratched up, tried a scratch remover, no go.
SO, did an fdisk, format, reinstalled Win ME, boots fine, but No mouse is
recognized.
Tried using add new hardware wizard, tried several choices, Serial/ps2,
reboot after each , still no functioning mouse.
Any thoughts as to how to resolve this?
Thanks
Brandon

| Restore Deleted Files Guest 16:25:49 |
| | Hi, I have a 20GB notebook, with a 200GB external hard drive, and I
need to restore about 150GB of deleted raw video. The undelete
programs find the deleted files very well, but I need to copy it to
another drive, and don't have enough room. The external hard drive is
untouched since the delete. It seems the files are there. Is there a
way to restore the deleted files on the external hard drive "in it's
place", just restore the folders and files so it's available? Thank
you.

| Error 732 while executing batch with PM8 Patrick E. King 18:18:24 |
| | I trust this is the correct forum for this post.
I'm using Partition Magic 8 to copy the boot partition(NTFS) to a new drive.
I receive the above error and the copy does not succeed.
KB article at Symantec advises using chkdsk /f or /r.
I've tried both to no avail.
I notice there are 2 fragments in the MFT of the boot drive which the OS
defrag does not repair
Could that be the source of the error?
Any ideas please?
TIA
Patrick

| Asus Motherboard Problems Aedis 02:45:45 |
| | OK. my computer will not turn on. I have an ASUS A8N-e motherboard and
the status light on the board keeps flashing green whenever i geive it
power. However, it will not turn on, no fans or anything come on.
THe first thought that came to my mind was "bad PSU"...this was because
there is a faint buzzing that the PSU emits that is in synch with the
flashing led on the motherboard. But with firther troubleshooting, i
ruled out a bad power supply by shorting 2 pins on the 24-pin connector
which turned everything that was hooked up to the PSU on, but not the
Mobo because it was disconnected.
So now i am stuck and wondering what i could do. The online retailer
(newegg) will not accept it as a return because it is past the initial
30-day period. Asus tech help is kind of flaky, and the search on thier
forum doesnt even work.
So i was wondering is anybody had any good ideas to try and also
whether or not ASUS has any type of warrant on thier motherboards. ANy
info would be helpfull.

| Sony Vaio Desktop - Recovery after harddisk failure DVDUsr 11:57:59 |
| | Sony Vaio Desktop - Recovery after harddisk failure
(hope this info helps someone out there)
Is this "delayed write" failure a Win XP problem or a Maxtor problem?
Sony Vaio Desktop model: PCV-RS720G
Win XP Home with SP2 (pre-installed by Sony)
System purchase date: 12/2004
Harddisk failure date: 7/2005
Harddisk: Maxtor DiamondMax Plus 9 200GB SATA/150 (3.5 Series)
HD Manufacture Date: 10/2004
I just encountered the notorious Win XP "Delayed Write" failure message.
It looked like XP was trying to write a registry entry when it croaked.
After a shutdown, the system would no longer boot.
Attempting to boot Win XP into Safe Mode caused the system to restart repeatedly (after it loaded System32\Drivers\Mup.sys)
Partition Magic 8 reported Critical Error 1601 (NTFS error) on the hidden 6GB partition created by Sony, and Critical Error 45
(checksum error) on the C: partition.
PM could not fix any of the partition errors.
Sony Tech Support (chat) told me to restore the system with my Vaio Recovery disks: 1 startup CD, and 1 DVD containing all the
software the Vaio ships out with.
But I didn't want to lose all my data on the HD just yet.
Sony Tech Support (toll-free number) said I could buy another HD, and try the Vaio Restore on the new HD, then try to copy the files
from the damaged HD installed as a secondary.
They would not officially support this technique.
Booting Caldera DR-DOS 7.3 (with the Read-Only NTFS Filesystem drivers) from a 3.5" floppy enabled me to read most of the C: drive,
and I was determined to get my data off the drive.
But the USB HDD drivers in DR-DOS would not recognize an external USB hard disk I had, so I couldn't copy the files off the damaged
hard disk 
Booting with Symantec SystemWorks 2005's "Recovery Disk" CD enabled me to access my external USB hard disk, but it could not see the
files on the damaged hard disk
So I bought a Western Digital 300GB SATA HD ($139 (after $50 rebate), from Fry's), partitioned it into 6 + 280 , with the 280GB as
an active primary partition.
The Sony Vaio Recovery process went smoothly.
The hidden 6GB partition somehow became a hidden 5GB partition after the Vaio Restore.
But I'm glad the Sony Vaio Restore/Recovery process worked as advertised 
When I booted Win XP off the new HD, Win XP was not able to read the damaged Maxtor harddisk.
Neither did Norton SystemWorks 2003's Disk Doctor
And PM 8 still reported a Critical Error 1601 on the hidden 5GB partition on the new HD
Is the Sony Recovery process causing the 1601 Critical Error in the partition area?
I didn't want to see another HD failure in 8 months when my HD fills up, so I decided to use PM to get rid of the hidden partition
and merge it with the NTFS partition.
I also created a 40GB FAT32 partition at the end of the WD HD so that I could write to it from DR-DOS.
I booted back into DR-DOS and painfully copied the files I wanted off the damaged Maxtor HD to the FAT32 partition on the new WD HD.

| Changed video card, now no sound???? Noozer 03:22:03 |
| | Just wondering if anyone has an idea as to what happened here...
A few days ago I removed an ATI Radio 9600 Pro and installed an eVGA NVidia
6600GT AGP video card. Since this time, the onboard sound has been flakey
and currently is not detected by the Device Mangler of XP Pro SP2 at all.
Mainboard is an Asus P4C800E-Dlx. Onboard sound was great until the video
card swap.
CMOS does have the onboard sound set for Enabled... Don't see anything else
that would affect it there.
Ideas?

| Problem w/ Netgear WGT624 v3 Guest 06:57:46 |
| | Hi All,
I've been having intermittent problems with the wireless access point
on my Netgeat WGT624 v3 (wireless router).
It goes like this: everything's humming along nicely, both wireless and
wired connections to the router are great, and then all the sudden, all
traffic stops flowing across the wireless "port" on the router.
Meaning, machines are still connected, the "signal level" still shows
up strong, but no data is flowing. New machines can connect, but they
won't pick up an address via DHCP. If they've got static addresses,
they connect fine, but no data flows either to the router, or past the
router (out to the internet).
All machines connected directly to the router via CAT5 still work fine.
Everything in the router web admin tool looks fine, and it reports
that the wireless is up and running, and it even shows devices
connected wirelessly.
The only indication that there is a problem is that on the front of the
router, the LED that shows wireless activity is blinking slowly
(perhaps 1 flash per second?), and steadily. Not the fast, chaotic
flashing you see typically see where there is real network activity.
Sometimes things will work fine for weeks, then we'll have 3
"breakdowns" in the same day. Other times it seems to happen almost
every day. The problem never fixes itself, so I don't think it's
intermittent interference.
The only thing that has ever been successful in fixing this problem is
pulling the power to the router and plugging it back in. That has
invariably fixed the problem once it comes back up, which probably
takes about 30 seconds.
Again, it's a Netgear WGT624 v3. Firmware version is V1.0.128_1.0.1.
There is a utility in the web admin tool to check for firmware
upgrades, and it tells me that I have the latest version for my
hardware.
I am running WPA. There are only 2 devices that regularly connect: an
XP Pro laptop with an integrated 802.11g adapter (I believe it's an
intel chipset), and a Netgear WGPS606 (Wireless bridge). The bridge
connects 2 other devices, and XP Pro machine, an a Mandriva Linux
machine.
The WGT624 has a few "extra" features such as a "range extender" and a
bandwidth doubler that allows it to operate at 108mbps. Is it possible
those are causing problems?
Bottom line: does anybody have any suggestions on how to prevent fix
this? It's getting rather frustrating!

| Question on ATX Power Switch Pins and Case Switch? Guest 03:15:01 |
| | I'd like to better understand.
On an ATX MOBO you have two power switch pins to which the case on/off
switch is connected. It must be connected and the on/off switch
toggled in order for the PSU to run.
I can just put a jumper on the two pins, but the PSU doesn't seem to
want to run.
So I am wondering - what is actually happening in simple terms? Is
one of the two pins 'hot', and does the case switch 'pass' current via
the connector to the second pin or what? Or does the case switch have
the current and pass it to both MOBO pins?
Be gentle please.

| Western Digital controller board Johnnyzero 23:16:23 |
| | I'm trying to resurrect a "dead" Western Digital 40gb drive in order to
do some data recovery - it's a model WD400BB-00CLBO.
I was able to locate another controller board which has the exact same
part number as the original (2060-001092-006), but it's from the 20gb
"version" of the same drive - a WD200BB. When I install the new board,
the drive will now spin-up, but I only get the continuous
thrashing/clacking sound of the heads against the platters. I noticed
that XP's Device Mangler recognizes the drive as a WD*200*BB, so I know
that this is the problem.
Is there any way to make this board work with a WD400BB? Since it's the
same exact WD part number, I was thinking that they're must be a way of
configuring it for use with a 400 - perhaps a jumper, trace, or even a
resistor that you can change. Or is the drive type permamantly stored
in an EEPROM or whatever at the time of manufacture?
Any help will be MUCH appreciated. I can certainly buy another
controller board from a WD400BB, but I'd prefer to be able to use this
board if possible.
best,
JohnB

| Maxtor 3100 USB Hard Drive not recognized in XP Pro Jjo 02:55:20 |
| |
I recently bought Maxtor 3100 portable HD, with USB connectivity and is
supposed to be compatible with both USB 1.1 and 2.0 . It should not
need any driver when connected to XP computer. I have 2 computers one
notebook and one desktop, both running XP pro. I have no problem using
my HD on the notebook which easily recognized my HD when I plug it into
one of the 1.1 USB ports. When I plug the HD to the USB port of the
desktop (2.0), I get the message " One of the USB devices attached to
this computer has malfunctioned and windows does not recognize it".
When I take a look at the USB ports in the device manager, an "unknown
device" is listed. Other hardware runs fine when connected to these
same USB ports. What can I do?

| laser printer toner cartridge, re-manufactured, any good? `A tower nj 21:57:29 |
| | Hi,
I have a HP LaserJet 4L printer that I've never changed the toner cartridge
on. So I started shopping around on line tonight to see what they cost.
Most places sell them for $98, and remanufactured ones for $75, but on
pricewatch.com the cheapest ones were $30.
Can anybody tell me if it's ok to use the cheap ones? I mean this is a
really GOOD printer, and I wouldn't want to mess it up by using
cheap toner. If that's possible.
Thanks,
Mike

| Samsung HD160JJ/P Problem Richard 23:11:14 |
| | I recently purchased a Dell 5150C with a Samsung HD160JJ/P hard drive. When
running the diagnostic program Sandrasoft a message comes up saying that the
optimum speed is not being used. It shows UDMA 5 instead of UDMA7. The drive
is supposed to be SATA and I beleive therefore should be using UDMA7. I have
checked BIOS and everthing appears to be enabled correctly. Checked Samsung
site and downloaded manual for drive. It mentions a limiting speed jumper
for 1.5GB/S on 3GB/S products in rare occasions. Is this applicable to Dell
computers interface?
Any help would be appreciated!

| Meaning of refurbished ? Amiman 11:17:55 |
| | Dumb question time please. I've often read about refurbished
products being offered at a discount, sometimes not long after
the type was first introduced into the market. I know the general
meaning of the word in English, but exactly what does it indicate
as a trade item ?
I guess a used computer would be classed as 'refurbished' if it
was cleaned up, had some defective or obsolete components
replaced and then put up for sale again. But a refurbished
motherboard ? Esp a model that was introduced only a couple
of months back ?
Are such items those that were damaged in shipping or had
some manufacturing defects and were repaired ? Are they
reliable ?
