Old Laptop 'fixed disk failure'

Had 'volunteered' to help as best I could with neice's Fujitsu LifeBook 530D 120mz 800mb laptop (they still exist!)

She'd had a FDD failure (no operating system found etc etc)

For first 3 days, all ok.  Upgraded BIOS, put in 32mb RAM, new 1gb HDD and eventually installed Win98.

Then began to get consistent Fixed Disk Failures at bootups. BIOS can't see FDD - tried manual settings for master, auto, you name it - nothing.

To get into a deeper fug (English word - ignore it!) replaced HDD three times with Fujistsu 800mb (2) and today an IBM 1GB.

Could at first get the HDDs to work in my Gateway laptop and even tried my 6GB drive in the Fujitsu, but no luck.

Most success has been about 12-14 hours on one of the HDDs before that went down.

With bay exposed, am able to confirm that the HDD 'fires up' at boot up but totally not seen thereafter.  Tried coming in from boot 3.5 but again no master drive seen.

BIOS is Fujitsu 1.18a under a Phoenix NoteBios 4.05 (dated 1996). (updated from Fujitsu site this week)

Have just tried reboot and HDD isn't even firing.

Not on a laptop.  You would have to swap the mobo.  It does sound as if the controller or some component is bad on the laptop.

If this were a desktop I would say disable the onboard controller and put one in the add-in slot.  The controller is probably failing.  Does it have a second controller (as desktop mobos now have)?  If so, all you would need to do is swap to the second controller.  I don't believe laptops have that luxury.  Without that ability, a dead controller would mean you need a new mobo.  That will be an adventure to replace the motherboard in a laptop.

I'd suggest replacing the CMOS settings battery for a try before you do anything drastic. It may have been losing the HDD due to that, and I know it seems strange that it would not then let you reset it, but at that point other CMOS values may have been corrupt preventing boot, and only when it further drained enough to allow the CMOS to do a complete reset, did it let you put another drive in, or manage to recognise the old one. After a few days of use, does the same thing again..... So that's worth a try.

How do you know if your security is working?

Protecting your business doesn’t have to mean sifting through endless alerts and notifications. With WatchGuard Total Security Suite, you can feel confident that your business is secure, meaning you can get back to the things that have been sitting on your to-do list.

thanks both. RoadWarrior's suggestion will take a few days to work though, so patience please. Could I also add that as a UK member, the time difference means what seems to be much delayed answers so apologies in advance.

Just taken laptop apart.  CMOS battery is soldered on to MB and due to vagaries of case design, is stuck beneath the only part of the case that won't seperate.  If I try to get at it, it will probably snap off.

Plan B?

Can you take the hard drive out and try it in another system?  Try another hd in this sytem?  If another hd works in this system then the problem is your hard disk.  Can you try another cable just in case it has gone bad?

Does the old hard drive work in the Gateway?

The IDE controller on the laptop is bad.  Condsidering the age of the laptop, you are better off just tossing it in the dustbin.
