Bios and HDgb wrong

  zoobie 20:44 12 Aug 2007

I've tried every possible channel and master/slave combo to get my BIOS to recognize a second HDD's D drive's full capacity (250gb) but no go. There's no Bios update and it seems to be stuck on 57gb when it used to recognize it fine. BIOS recognizes my 250gb system C drive OK. How would I find the proper settings to edit both?

could a jumper have come off? some drives have a lower rating for some purposes and the jumper disables it.

Nope. I even just hooked up this drive alone and tried every jumper setting. Bios always shows 57gb on this drive. Same in Windows Disk Management. How do?

but what size does your OS report it as?

Do you have another computer to try it in?

Is it a brand spanking new drive? If so, what if anything have you done to set it up? (i.e fdisk and format)

OS sees 57gb. No other computer to try with. It's my regular HD slave I've had for 2 years. Diagnostics reports it to be the Primary slave, drive in good cond and the jumpers correct. I just put a new HDD as my system C drive and BIOS sees that fine. Perplexing...

What may have happened is when XP was installed to C, Microsoft fails to tell you to disconnect any other HD's. The D drive was turned into a RAW file format and possibly damaged. I've recovered most but now need to re-format D back to NTFS...but it's only reporting 57gb in Disk Management and BIOS.

I take it you have installed the service packs and updates.
If not, make sure you have sp2 installed.

So if you have had it (the drive) for two years was it previously reporting the correct size? And does bios correctly report cylinders, heads and sectors? If not does your bios have a custom option to try entering these details manually?

As skidzy has said you will need SP2 for XP to recognise large HDD click here for windows updates

The bios and the operating system already sees his boot drive as 250Gb. This drive is the same size. Mentioned in first post.

What does it say in disk management, has it got any un allocated space?

Or run killdisk from a floppy. You may have a sector of the drive in a different file structure. have been using linux?

  zoobie 18:25 13 Aug 2007

I have SP2 installed
Both HD's are the same size (250gb)
Disk management says D is all unallocated but shows only 57gb.
I've been using Linux but the Knoppix version which runs from the DVD tray.

I just stuck some other HD's in as slaves and they report correctly in BIOS and disk management. This leads me to believe the 250gb drive in question was damaged during the XP install to C drive.

I'll run killdisk today and report the results.
