Toshiba internal hard drive upgrade

By sanolte ·
I have a Toshiba Satellite M35 series with a 80gb hard drive going bad. I purchased a 160gb WD internal, installed it, loaded the OS from the Toshiba recovery disc but it will not boot. The old hard drive boots up fine but the new on just gives me a blank screen with a blinking curser after the BIOS boots. The hard drive is listed and recognized by the BIOS.

Any help would be greatly appreciated. Thanks

When you looked in the BIOS

by OH Smeg In reply to Toshiba internal hard dri ...

Did you save the changes as you exited the BIOS?

If you didn't the computer thinks that it still has the 80 Gig Drive in it and is attempting to Map the 160 GIG Drive as a 80 GIG Drive.

Yes I saved the changes in the BIOS however I think I've since switched them back to factory settings. Thanks.

System may only be 28-bit addressed . . .

by Who Am I Really In reply to Toshiba internal hard dri ...

I've found that on more than one occasion with PentiumM systems,
even when the chipset etc. is technically supposed to be fully 48-bit bit compliant, the nuts doing the BIOS forcibly limit it to 28-bit and some even limit the drive size below the max 28-bit LBA limit

- a 2005 Compaq NC6220 Pentium-M, Max. "Supported" HDD is limited to 80GB, though it will function with a 120GB, certain HDD tools don't even see the drive, and others can see the drive but can't perform any testing, etc.

and yet a 2002 Compaq Presario 6330CA P4 mini tower is fully 48-bit compliant and will use the the largest IDE drives available
(I have 1x 320GB & 2x 500GB installed in it)

one thing with recovery media is a lot of them just dump a block of sectors onto the HDD, providing the restore sees there is enough sectors to hold the factory installation
ie. if the system normally ships with a 40, 60, or 80GB HDD the restore media will restore to a 40, 60 or 80GB without questions

but if you were to put say a 10GB HDD in and try the restore it might balk at it
or start the restore and fail at some point near the 10GB mark or right at the end of the space.

with a 160GB drive installed the factory restore process sees enough sectors, dumps the factory installation onto the drive, but if the BIOS is limited to smaller drives by 28-bit addressing or forcibly programmed to limit the drive size, or both,
that could possibly explain the "no boot" issue

Try a smaller drive?

by sanolte In reply to System may only be 28-bit ...

So the only way around this is possibly to try a smaller drive? It's not a problem to take it back and get a smaller one.....I've already got clearance to do that from the seller. But if there was away around it that was not too complex that may be a better solution.

...then again I could always buy an external for more HD space.

Thanks for your help.

Seagate used to have a Utility called Disc Wizard

by OH Smeg In reply to Try a smaller drive?

That would allow you to fool the BIOS into seeing a bigger drive than it otherwise could. But It was messy to setup initially.

While the current version is called the same I'm not certain that it still does the same job as the old one did but it's free to download so it may be worth the time to have a look see.

It's been a very long time since I have used that function of Disc Wizard back when I was fitting 4 Gig Drives to 486's when the Promise Tech Controller Cards where not available so I'm not sure how to do it now.

The free version only covers seagate/maxtor products

Well actually

The free version only works if there is a Seagate Drive involved. Or at least it used to. So if you can add a Seagate Drive at all it will work with anything.

All it needs is to find 1 Seagate Drive and then you can use it to do as you like.
