Did some careful digging around today and found out I have definitely lost Diggory,Lady Elphinstone,Ophelia and Spindlestone Surprise :-[. All I found were some empty husks. The bulbs had been completely hollowed out.
As I am relatively new to snowdrop growing I was wondering whether this was due to narcissus fly or something else.

Sometimes here also tiny slugs do the job
but most of the time here it is the Narcissus fly larvae
but if you dig them up now they should be in the bulb
or they where there last year
and the basal plate isn't dead

Rick photos would help. If the bulb still looked fresh on the outside but was full of brown goo I would say Narcissus fly. If you wash this you will find the grub.
I dont think there is carefull digging around bulbs. Removing soil on top of OK. You dont want to break roots because they will not grow again until next autumn

It has been mentioned on the forum several times before... but if this is caused by Narcissus fly... you can sometimes salvage bits of the bulb and the basal plate, or what remains of it will form little bublets naturally... it's worth checking before giving up completely. I don't have much trouble with dreaded fly, but I've managed this a couple of times, although only with Vallota speciosa after one of the blighters found its way into the greenhouse and with a daff.

That's exactly what I did Mark, I carefully removed some top soil, but as there was no sign of growth I "dug" a little deeper.
Unfortunately I didn't take any pictures.

Rick - I know how distressing this can be especially when you have been so looking forward to seeing your rather expensive little treasures bloom.
For this reason I began growing my bulbs in lattice pots. It does not stop it happening but it enables you to keep a check on the bulbs when they are dormant. That said I am having lots of bulbs rotting in lattice pots this year with all the rain. I now make cloches with net over them from old hanging baskets and place over my favourites as soon as they have finished flowering. I secure the basket with a few metal pegs pushed into the ground. In one sunnier area this is seeming to work.
I now intend to grow all my snowdrops under deciduous trees in my unprepared woodland area where Narcissus Fly are less likely to be active. I am not saying they will not venture up there but am told they prefer to have a bit of sun on their backsides when egg laying ???
Once you have bigger clumps of more vigorous spreaders the odd bulb goes un-noticed but I understand the disappointment when it is your only bulb. Don't give up hope

I have seen them in deep shade

Thanks for the advice Jennie. I think I will give cloches a try this year as well.
