Stubborn Hard Drive Doesn't Want to Revert to Basic Disk

[Guest ey.markov@iname.com]

Greetings,

 

Some time ago I aborted a conversion to dynamic disk in my W2K Pro

machine. I have attached a 250 Gb drive as slave, went into Disk

Management, converted it to dynamic. Then, when I issued the same

command for the first disk, the "Are you sure?" message reminded me of

the drawbacks, so I clicked "No" and reverted disk 2.

 

Problem is, ever since then disk 2 stubbornly shows as a 128 Gb drive

under Disk Management. DOS tools see it properly, and I was able to

partition it (32, 80, and 130 Gb), but almost every other day Windows

would tell me that the third partition (the one that crosses this

imaginary 128 Gb border) is corrupted, would run CHKDSK on it on

startup, and sometimes fix it, sometimes corrupt all the (test) data

on it beyond recognition.

 

I thought: "Dynamic disk info is stored in the last 1 Mb of the drive,

right?" Last night I ran Boot and Nuke and had it write zeroes to the

entire disk 2. Booted W2K after that... and what do you know - not

only did the drive show up as 128 Gb, it was once again labeled

"Dynamic"!

 

If anyone can shed some light on what the heck is going on, I'm sure I

will not be the only one to be enlightened. Thanks!

Does your BIOS support disks larger than 130 GBytes? If

yes then you must enable 48-bit LBA - see here:

Now convert your disk back to Basic, using the Disk Manager,

then create the partitions you want.

Whatever DOS tools is, it's using the BIOS to access the disk drive,

so the 48-bit LBA capable BIOS allows full access to the 250GB drive.

The problem is your Windows 2000 installation is not properly

configured to support 48-bit LBA. See

Thank you so much! That was it.

 

And to think that this was a clean install of W2K SP *4* on another

250 GB drive...

 

Now where do I ask about why the system restarts itself after a soft

shutdown?
