Urgent - Lost Harddisk partitions

I have a development machine that has 3 harddisks. When I develop I have a slide-out removable boot harddisk that I can change operating system Win2k,Win98 etc for testing.
The other 2 harddisks (19gig each) remain in place. In the course of testing I have zapped the two fixed harddisks, I think it was when I was installing NT4 on the removeable boot disk, I noticed that the installation was saying 'deleting pagefile.sys on D:':(

When I look at the two fixed disks under Win2k the disk manager says they are un-allocated. Can I recover these partitions - and how?

Give easy recovery a try, you can find a demo version at www.ontrack.com, afaik it will also recover from lost partitions.

You don't say how the hard disks were partitioned, or whether you were using anything like volume sets. Normally installation of a system on one of the drives would not cause data loss on the others, unless the other drives were set up in a special way eg. volume sets, mirroring etc.

I just have a few questions that might help in fixing this:
1- About the hard drives, are they Maxtor brand? Are they formatted with NTFS?

2- Which service pack, if any, does you Win 2000 have?

I ask the above because I have just seen that a Maxtor 19.8GB hard disk showed up as 7.8GB in Win 2000 after SP2 was applied. When the old atapi.sys from the original Win 2000 was used, the drive was recognized as 19.2GB again.

If the drives are in FAT32 format, maybe you can try to access them on a Win 98 system. Hope this helps.

THe drives are FAT32 drive formally called E: is a Seagate st320413a with two partitions.

The other lost partition is on a Quantum fireball also FAT32. Theis disk is split into 2 partitions one of which is intact.

They are all normal partitions, no volume striping etc.
Booting to any operating sytem does not see them.

One thing you could do, but I'm not sure if it works, is that you set up new partitions that are exactly the same like the old ones, might be that then you have access to your old data again, just set the partitions do NOT format it. This is what I would try as a last thing, if nothing else helps.

The commercial software "Partition Magic Version 6" has some capability to "repair" corrupted partition-definitions.

Dear MarcG
making new partitions will LOOSE SOME DATA
I solved many problems like that
(Mainly data recovery after CIH Virus)

I Noticed that FDISK does not only write sector 1 head q CYl 1
but it also writes each beginning sector in each head

SO PLEASE DON't try FDISK


1 - Please just make a Hard copy of the drive before trying DATA retreival
(that can be done by Norton utility starting from NU6 (under DOS) u can select physical sectors starting from (cyl 0 , h 0 ,sec1) and save them PHYSICALLY on an other HArd (Saving as file will take a very large time)

then U can try norton utilities
(If some body is expert in using Norton DISKEDIT )
thanks
