I've had similar problems. In the end, I changed the owner of the folders/files to my account, then I was able to delete all that I needed.

Using Windows Explorer, find the folder you need to change.
Right click that folder > Properties > Security Tab > Advanced > Owner Tab > Edit
Select the account of the new owner, tick the box labelled "Replace owner on subcontainers and objects", Click OK.

That should sort it and allow you to delete any files in that folder's hierarchy.

Perhaps that's the difference. SRS manage to sell their stock at prices people are happy with. Phil on the other hand probably doesn't sell much Pentax kit, he just keeps a lot in stock.

Leaving a drive set to 'Cable Select' leaves the decision process to some electronics of unknown intelligence with no guarantee that it'll decide correctly.

My recommendation is sound, and guaranteed to eliminate further frustration from incorrect drive identification. Put the link on to make it a 'Master', it will work, leaving it as 'Cable Select' may not.

Yes, I know. I think he knows too, but your post doesn't help him with his lens issue. Mine hopefully did.

I think you've just been unlucky, that lens is held in high regard around here.

In Europe, you would be within your rights to ask for a full refund or a replacement lens.

This is a duplicate thread. Please post a topic only once. Now we have two conversations about exactly the same thing.

Please continue this discussion in the other thread.

1: Check that there is a jumper on the drive to make it a 'Master'.
2: Use the Microsoft Disk Management utility to delete any existing partitions on that drive, assuming you don't want to keep anything that may be on it.
3: Use the Microsoft Disk Management utility to create a new partiton.
4: Format the drive (hopefully).

I think Stefan dealt with that, but he doesn't seem to be very active here any more.

It might help if you told us the exact model numbers involved.

Well the postage is 'free'.
