[ILUG] Agh! Help!

[phil at techworks.ie]

Hi Just a quick update:

First of all, thanks for all the replies!

My first partition /dev/hda1 is actually my win2k partition which I keep around for things that I just can't run on linux (like the Ericsson T68 sync software).  So if the start of that is trashed, I don't really care, as it is FAT32, so I can read it.

I am using gpart at the moment to scan the disk, and it has found 2 partitins so far.  This is a 48G disk so it is taking a while.

Once I have succeeded though, I'll put a bit up on the web about it.  It is always useful.

Phil

If you know the *exact* partition boundaries and types, you _may_ be able
to just remake them using fdisk (do NOT! mke2fs them after or you'll
definately lose them!).  If the first partition is something easy (eg
/boot), you might get all your data back from other partitions but you're
not likely to get /dev/hda1 back (IMO that is...)
