40Gb only formats 8Gb

By Moostique ·
My original 13Gb drive was corrupting and I needed more space, so I bought a 40Gb. However, it will not format beyond 8Gb. I know this a common problem, but the answer is elusive.

Model: Dan Explora Plus
Purchased: March 2000
BIOS: Supermicro P6SBA (0916991530, r2.2, November 1999)
OS: Windows 98, 2nd edition
File Allocation: FAT32
Primary Master: 13Gb EIDE Western Digital
Primary Slave: 40Gb EIDE Western Digital
Processor: 551MHZ Pentium III
Memory: 128Mb Ram

I have tried two ways: (a) With 13Gb master and 40Gb slave, and, (b) with 40Gb on its own. Each time cables and jumpers are re-set accordingly.

1) If I boot to Startup disk the BIOS recognises the drive as 40Gb. FDISK then asks if I want to enable large disk supportfor FAT32 partitions. I click "Yes" and am always returned to the A: prompt, and can’t go any further. This happens whether I use the original Windows 98 CD or the Start-Up disk.

2) I can format the drive in Windows, but only 8Gb. Windows actually thinks it has formatted an 8Gb disk, even thought BIOS knows it is 40Gb.

My local store replaced the 40Gb, but still no difference. The drive has also been tested with Partition Magic and on a newer PC running Windows XP. Since my PC already runs a 13Gb drive I'm puzzled.

Dan, the manufacturers, are now bust, but I have contacted Microsoft, Western Digital, and Supermicro. I have tried their Knowledge Banks and helpdesks, and submitted my problem to a couple of other usergroups. Aargh - still no solutions!

Supermicro implied that my BIOS is up-to-date. Besides, I don’t want to flash it in case I do something drastic to the PC, (I’m no expert). They did suggest I disconnect my ZIP drive before formatting, but I can’t see how this will help.

Windows problem, BIOS problem, or my problem??!

One of the most common problems people have with hard disks, especially when trying to add a new hard disk to an older system, is the frustration of finding that not all of the hard disk is actually accessible. This is almost always due to BIOS and operating system issues that are a result of short-sighted planning done by the people that invented hard disk structures, access routines and operating systems many years ago. In some cases they are due to actual hardware or software bugs that are not detected until hard disks grow in size beyond a certain point.

Fortunately, there are now solutions to most of these problems. This section takes a complete look at these issues so you can finally understand what these barriers are all about. Hopefully. :^) And then also hopefully, solve the problem through hardware and software changes.


Note: Most of the issues discussed here are due to BIOS issues, and hence of relevance primarilyto IDE/ATA hard disks and not SCSI disks. Some though are also relevant for SCSI drives, especially ones that are due to operating system limits.


Note: The pages in this section are focused primarily on explaining the nature of the various harddisk barriers and how they come about. To avoid duplication, I do not discuss how to deal with size barriers here, because the techniques are common to many different barrier types. Look at this section for details on overcoming size barriers.Next: Older Size Barriers

Thanks.

Unfortunately the suggested website only showed all the familiar problems and solutions.

My BIOS is apparently up-to-date; the PC runs FAT 32; and my PC already copes with a disk larger than 8Gb. There's no reason that I can see for a problem.

Start with this Microsoft Knowledge Base Article

If your existing drive has a drive overlay program installed, that may explain the 'weird' behavior.

If you do have a drive overlay program, I suggest that you use Western Digitals Data Lifeguard tools to setup your new drive.
This way, you are at the least risk of loosing data from the original drive.

Also, check the jumpers on the new drive to make sure that it is not set to limit the drive size.

hmmmm. How is your zip drive connected and what drive letter is it using? How many cd-rom drives do you have?

What drive letters are assigned to the following?
13 GB drive
cd-rom
40 gb drive
zip drive

Are you using On-Board IDE controllers? You might want to try purchasing an PCI ATA drive controller and plugging it in, and connecting the hdd through it.

It's probably a hardware issue... maybe the disk controller or systemboard/bios is starting to fail. (If you format your 13GB hdd, you may find that it no longer goes above 8 gb either <-- I don't recommend doing this -- just maybe why it "was" working and now is not).

1)Maybe your hd has 32Gb clip jumper ability?
Set it and run fdisk.
2)Maybe earlier on this hd was different from Windows OS?Try to look to hd from Linux setup.
