How to recover a Photoshop Image that was corrupted with 10.5.3

Question

As so many people have faced loosing work because their images have been corrupt when saving across a network, I thought it would be a good idea to make a separate topic for this possible fix/recovery.
This will only work if you know the dimensions of your file in pixels and the number of channels in the image. Also all your layers will be lost, but as a last resort this is worth trying:
In Photoshop choose File > Open
Change Enable to "All Documents"
Select the corrupt image you would like to recover
Change the format to "Photoshop Raw" and click OK
Now you need to enter the pixel dimensions for the image and enter the number of channels
then go ahead and open the image.
If you are lucky and have entered the correct dimensions there is a good chance you will now have a usable image open.
If you get the dimensions wrong or if the image is too badly corrupt you will probably be looking at a load of coloured lines, try a few more times with different dimensions and you may get something you can work with
Good Luck

When a POP account is deleted from Mail Preferences Accounts, all the mail files locally cached are deleted. A warning splash screen comes up and tells you that, when you are deleting a POP account from Mail Preferences Accounts, and it asks you are you sure that you want to proceed deleting the account. If you had originally configured the account setup to leave downloaded messages on the server and to store drafts on the server, then recreating the account configuration in Mail Preferences Accounts would, I believe, get you back to normal. Otherwise, you may be needing to use some data recovery software, but after a week, it is likely that those deallocated blocks of hard disk, where your mail and important draft resided, have likely been overwritten and are now unrecoverable.
You may want to consider getting an IMAP account somewhere for the future, where deleting an account configuration from Mail Preferences Accounts does not affect mail stored on the IMAP server (or drafts, if you store drafts there, too). IMAP also has the added benefit of staying sync'ed between multiple computers, too. Some email providers are not too keen on them because then they have to provide storage space for customers above and beyond storage space for their new incoming unread mail; that's why they do POP.
