can't access a partition on my backup disk

I have a 20 gig backupdisk in my system, partitioned in aprox 10/5/5 gig ratio
all of a sudden the system jammed and after a reboot it was telling me that the systemdiskette was incorrect and I was told to replace the diskette...
I changed a little in the bios concerning the bootsequence and all was fine when I replaced the IDE 0 for another.
Ide 0 is not the boot- a.k. systemdrive so it would not be of any importance.
But now when the system seems to be up and running, I can't access the specific drive...

I work with XP Pro edition on a 2000+ processor
The station configuration is as follows
C- 10 gig HD, not partitioned, shared
D- CDrom
E- CDwriter
F-part of 20 gig HD, 10 gig availlable (used to be shared up to now)
G-part of 20 gig HD, 5 gig availlable, shared
H-part of 20 gig HD, 5 gig availlable, shared

Its probably needless to say that the info in the HD is important.
Can anyone help me out on this?

Hi Greenkodiak,

>>I can't access the specific drive...
Do you get any error messages? Is the drive visuable in disk management?

Greetings,

the drive is visual along with all the other drives, but only the "hand" (as a token of beeing shared) is missing.
When dubbleclicking the drive, a small window pops up telling me the drive is not accessable.

In an earlier moment a message told me that the disk needed to be formatted, which I did not do of course.
In the preferances I can see that the disk is compleatly full (blue) while there is nothing on the disk (0 bytes)

Hmm... you will probably have a hard time recovering the information without the use of any tools then.
Please check the following list of data-recovery tools: http:Q_20411871.html#7515947
Personally I had great success with GetDataBack from http://www.runtime.org/
They have a free trial that will tell you if it's able to recover the data, if it is, you'll have to buy the full version to actually recover the data.
Another thing you might want to try is Testdisk => http://www.cgsecurity.org/index.html?testdisk.html which is a tool to check and fix partion information, which might be able to recover everything without the need to copy everything over to another disk.

Are there any assigned drive letters for the disk in diskmanagement? If not just try to assign driveletters.

Righton LucF!
You prevented me for having another bad night!
The runtime prog did the job. Costly, but effective!

Disadvantage on such cases is that due to the missing structure, all the files contain lots of stuf I dont need.
Takes forever to filter out the important ones. But the by far most importand file is recovered and I'll keep on using the program in the future.

Tx!
