Bad Geometry

#1 Post by Roy78 » 24 Feb 2015, 21:24

Hi everyone!
Below is a screenshot of a the system-partition of a small business server 2011, the server boots up normal with no problems, although this partiton is active, has the boot-partition and the system on it.
Is there anything i can do with testdisc or another tool, or should i leave it as it is, since the server is running correctly?
The only problem I got is, I cant do image based backups of the server, because of the bad geometry.
The disc is on a raid 1 on a lsi-megaraid controller.

Thank you for reading and helping!

3 possibilities:
- the safest: do nothing
- Run TestDisk from a LiveCD, Advanced, Boot, RebuildBS, List. If you can see your files, choose Write, confirm, Quit
- Run TestDisk, Analyse, Quick Search. Choose to Write the new partition table, confirm, Quit and restart the computer.

If it's a Raid 1, you may want to keep a harddisk as a backup until you have verified that everything work as expected.

Thank you a lot, cgrenier!

For now, I think, I will stay with the safest possibility, and leave it as it is.
One day I will virtualize the server and then i'll have to fix the bad geometry, so your given steps are a great help.
In fact it is on a RAID 1, so your Idea with keeping one disc as backup is brilliant!

If I ever do it, i can report back here, if it is okay to dig up old threads, because this would probably be in a couple of month/years.

Thank you once again!
