Recovery Mode does not find internal nor external storage Before I had CyanogenMod 9 on my Samsung Galaxy S i9000. Then, suddenly it did not boot anymore and I could not boot into recovery mode neither.

So I flashed different kernels with Odin (speedmod, vodoo) to be able to boot into recovery mode - which worked.

Within the recovery mode (ClockworkMod Recovery v5) I can not access neither my internal storage nor my external SD card.
I just see: unknown volume for path [/cache...]

Also tried the vodoo Kernel with ext4 support (as I assumed CM 9 uses ext4).

Which steeps are necessary to get the phone working again? I can not access any storage at all...

I appreciate your help!
You should use Odin or Hiemdall (preferred) to flash a new ROM, and or flash a new partition table.

It sounds like the partition's have been erased, and as such should be remade by flashing a new ROM.
