I bought a brand new Maxtor Diamond Plus 8 160Gb Hard disk last week,
partitioned it up into about 5 partitions, put various files and
downloaded stuff on them, then all at once like today, none of the
partitions were available!
Win2k reported that folders were not available and were corrupt.
So, I rebooted and the HD was found ok on bootup; fdisk reported only
25Gb available, but maybe that was just fdisk. I booted back into
Windows and all the partitions on that disk had disappeared.
I then ran PM8 and re partitioned the said disk again, but I am loathe
to put anything on it incarse the same thing happens.

Any ideas as to what may have caused it? I did NOT do anything out of
the ordainary on this machine at all. It just happened??

Thanks

Hard drives don't format themselves, but viruses format them. -Dave

You say you partitioned it, but did you format each of the partitions?

If you happen to be running an older version of Intel Application
Accelerator (older than v2.3), it is capable of corrupting partitions.
Of course, I found this out after it wiped out my operating system.
Documentation for the later version mentioned that Intel had fixed
an associated addressing problem.

Unfortunately, it may also be that the drive is bad. If you haven't
already run a scandisk/chkdsk with a full surface scan, you should
probably do that.

Well, yes I agree that could be a possibility, but I wonder why my other
drives were not affected, especially the one with my OS's on???

I ran a spyware/malware check last night and my AV program runs every
morning.

Thanks anyway

Yes I did format all the partitions, and I put files on them, which I
have now lost!

I think most of us are puzzled about why and how your name brand
hard disk drive formatted itself. Please report back when you find
the answer.

I know it sounds stupid and in reality it couldn't happen, but after I
partitioned it last weekned, and then put some files on it (data and
media), this weekend it just went to 'unallocated space' in PM8. So I
take that to me unformatted. So in reality all the partitions were lost
and it became just one 160Gb disk again

I don't suppose I will find an answer, but I will report back if I do

Thanks

One thing I forgot to mention was when I was burning about 350mb to a
CDR from that new drive, I heard some ticking sounds, and I thought it
was coming from my CDRWriter, because when the burning stopped so did
the ticking.

You didn't turn on 48-bit LBA, and when a data write was made at the
137GB boundary, it "wrapped around" and scribbled over the beginning of
the disk, which contains the boot sector, partition tables, and (if
running FAT32), the FATs.

Ticking or clicking coming from a hard drive is often a sure sign of
impending failure. I'd run Maxtor's diagnostic program to check the
hard drive out if I were you.

I don't run any Intel stuff at all here, so that's out.

After I re partitioned the disk back to what I had before, I ran a disk
check on all of it and no problems were found.

mmm, strange as to why it happened in the first place

Well you are right there I suppose!
No, I didn't turn on 48-bit LBA; I didn't think I had to. doh!
I upgraded the BIOS to the latest for my mobo, and have the latest sp4
for win2k, so I thought that would be enough. Not so it seems.
I have now enabled big lba in the registry.

Just out of interest, someone in another NG suggested it could be
software rather than a bad disk.
I was writing/burning a CDR from that drive at the time of the clicking.

I've seen exactly the same thing about 2 weeks ago.
Professors computer blue screened, and would not
recover. OS was W2k. I booted the computer with
a WinXP install disk, and ran chkdsk from it. That
recovered the W2k disk. He had 2 disks, and both
were whistling like the dickens, so I recommended
that he let me ghost his primary drive to a new drive,
and then copy his 2nd drive to another new drive.
That worked fine, except he said he was missing one
of the partitions ??? I went back and looked on the
2nd old drive, and sure enough there was the missing
partition. So I copied it over to the new drive. While
I was doing that, it suddenly occurred to me that
the missing partition was the only one on the drive,
when I had previously copied 2 other partitions from
that drive ????? Also, the missing partition was now
80 gig .. the full size of the 80 gig drive. I know there
are two other partitions on that drive, because I have
them copied over to the new drive. I have not a clue
why this happened. Interesting that the same thing
happened to you. Sounds a lot like a new virus. I
handed the Prof a stack of blank cdrs, and told him
to get started.

Well in my case it seems that I did not enable big lba in the win2k
registry or more so it was caused by the 48 bit lba thing. That being
windows did not recognise my 160Gb disk as that.
But I know what you mean about using blank cdrs!

After posting this message (above) to the storage NG, the consensus of
opinion seems to be that I did not enable big lba in the win2k registry,
or rather it was a 48 bit lba issue.

So now I have enabled big lba, and I hope that sorts it.

Just off hand I'd say you don't have 48 bit LBA active so Windows doesn't
handle it properly; causing it to become corrupted when you write a lot of
data onto it.

I agree with David Maynard.

Ok, so what is the difference between active and non active.
Your post seems to have arrived after my update so I am still wondering
if I have it sorted.
Thanks

I hadn't seen your follow up messages when I posted.

Sorry for the confusion. What I meant was there are two areas that must
support 48 bit LBA. One is the motherboard BIOS but, odds are, yours is
already 48 bit LBA or else you'd be wondering why the motherboard doesn't
detect your 160 gig drive as being 160 gig.

The other is Windows 2000. That takes service pack 3, or later, (or a post
sp2 hotfix but that's a moot point with a later service pack available) and
the registry key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\atapi\Parameters

set to 1

If the key isn't set to 1 then 48 bit LBA isn't enabled (I.E. active) even
though it's 'supported' (because you installed the appropriate service
pack) and just installing the service pack doesn't automatically set it.

Run Disk Management, and if it shows the entire capacity of the drive,
then Windows 2000 is set up properly. In order for Disk Managment to
show the entire drive capacity, two conditions must be met: 1) SP3 or
SP4 applied to the Windows installation and 2) EnableBigLba entered
into the registry.
