invalid system disk

[tinwindow]

Hi ya' all......
I need help with a computer that boots to a screen invalid system disk ..
after put in....hit any key to continue.........
Started when they had generator on from a power outage problem.......
I looked at it and it booted without a problem did a few improvements and it was working great when I left......
got a call it is doing the same thing......
Could this be a voltage problem ?
they do have a lot of stuff on one circuit.
or might it be a hdd issue....???
I am confused.......

It could very well be a bad drive. Did you run any diags on the drive yet?

[tinwindow]

Not yet Mdk. ....
I presumed when it died it died........
the bios recognized it........

[tinwindow]

the drive worked great when I was there......
booted several times ...
it is a WD......should I diag it ?
I will have to go back this week end......

Diag it for sure, so you know where you sit.

[tinwindow]

ok......train..
thanx ...
I will have to use a dos boot disk........
can ya ' point to the place to get a diag now and download......
I am sure I have several but have to look all over......

[Midknyte]

You can just download UBCD from the link in my signature. It has WD diags, as well as a bunch of other useful apps.

[tinwindow]

Thanx Mdk....
hit the link......
could ya' be a bit more spesific ...
something I can put on a bootable floppy......
no ability to pay for help but appreciation is greatful......

Why floppies? If all you can do is floppies, then go to the WD site and grab em.

Just download the.iso and burn it to a CD. If you don't know how to burn .iso files, read the FAQ.

the cd didn't boot but the floppy did.......
I know they both were bootable on my computer........I tried them.......

I like to think I have a bit of wisdom of tech........
wd site, where I downloaded the iso diagnostic program says ...

am I missing something ?

MDK???

[Midknyte]

? So you downloaded the WD diags .iso and burned them as an image?

Unfortunately, I'm not running a WD drive, so it closes saying "non-wd drive". You should run a quick test, then the extended test if the quick test passes.

WD floppy

Used the EXE and that is messed up. Can not load and the A:\> showed up.
Reason, Can't load BDOS kernal file: A:\IBMDOS.COM
Might want to double check if it is a WD hdd.

The CD works just fine , Data Lifeguard Diagnostic for DOS (CD)
I use Diag504fCD.iso

Dr Dos and the a prompt......
What the heck am I doing wrong...........

i surely would appreciate a push into the right direction......
Thanx in advanced....
