LOL @ Kolenka!! I very briefly played with Calibre when I had my 300 & 350. I couldn't get the hang of it and stuck with the Sony software which worked perfectly fine for me. The new Sony software - not a snowball's chance in heck!! I'm running manual. I just may have to give Calibre a second play because the Sony one is just not happening.
I dropped by the Sony store today to chat with the guy that sold me the unit. He has and uses a 300 so he claims to be familiar with the units & the software. I explained briefly the differences in the software. He didn't understand why it would do that so then I showed him my reader. The only Synced collection on my T1 is the Sony Documentation and it perfectly illustrates the frustration of not being able to add to or delete from collections that have been synced with the software.
I showed him the greyed out stuff that I can't even select that collection. He tells me to keep pressing it. Ok bud! And because I touched the screen too quickly and too many times for it to handle it crashed. He reads the error on the unit & says 'oh my!'. LOL You got that right!! He says he's going to bring it up with the tech guys. I don't think it'll get anywhere but you never know.
I will give Calibre a go and see what happens.
Thanks for your efforts in helping those frustrated T1 owners with bald spots. LOL
