I can mount the disk from an alternative Haiku nightly installation on
another disk but cannot access the 'Desktop' folder on the faulty disk.
If it's important data, copy the whole disk partition (or even the whole disk
drive) to somewhere else (USB disk drive or a disk over the network, etc).
Possibly use a Linux live boot CD like Knoppix. Open a root shell, and copy
the disk partition (named something like /dev/sda2, use fdisk /dev/sda to list
them all) to that file somewhere else. You can use compression too, such as in:
gzip -c < /dev/sda2 | ncftpput -c -u UserID -p Password OtherComputer.domain
DestPath/SavedPartition.gz
Then boot up Haiku (possibly from a Haiku live CD), mount the bad disk and try
"checkfs /YourDiskNameHere" to see if that fixes things. If it makes a mess,
copy the saved partition back to the original one and try something else.
You can also get fancier by using a virtual machine to attempt repair on a copy
of the disk, which has the advantage of letting you revert changes to a
previously snapshotted state of the virtual disk rather than copying the whole
partition.
