I backed up and hotsync'd before installing Sprint Update 1.12
The update went fine.
I backed up again.

A couple of hours later I could not access an app because it was on my SD card...and my Treo would not, could not read my SD card
I could not do a restore because...the backup was on my SD card
Filez couldn't read it cause...u know.

I took my SD card out and put it in a reader...SD card is fine.
So I hotsync'd. Still my Treo could not read my SD card.

So I panicked and reinstalled the Update and did a hotsync of my apps.
It's fine now...reading my SD. I did a restore and guess what? My Treo could not read my SD card again

So I panicked again and reinstalled the Update and did a hotsync of my apps. This time no restore. Everything is fine...reading my SD. Have to set some of my prefs.

Scary: Treo stops reading ALL SD cards. Most of my apps are on the card, including the backup set. And my backup set is corrupted whereas if I restore the set it causes Treo to stops reading ALL SD cards.

My computer and HOTSYNC was my saving grace today.
