Here are some preliminary results of my testing, that seem to point out that something is wrong in the Calibre-SD card combination.

I am using Windows 7 x64.

1. I Install Reader for PC, format my T1 memory and card, and sync:
(a) 100 fully standards-compliant ePubs to the main memory and 40 fully standards-compliant ePubs to the SD. Result: The T1 takes a long time to refresh the thumbnails, but everythings works as expected - except a missing cover/thumbnail. All ebooks display their correct metadata in the "info" page, open and behave correctly.
(b) I now add 10 probably "not fully standards-compliant" (but acceptable) ePubs to the SD. Result: They also behave as expected. No problems.

2. I reformat the T1's memory and SD and start testing with Calibre:

(a) I transfer the same 100 fully standards-compliant ePubs to the main memory, in groups: first I transfer 20 and check that everything is OK, then 40, then 60, then 100. Results: The T1 shows most thumbnails almost instantly (compare with above) and everythings works as expected. All ebooks display their correct metadata in the "info" page, open and behave correctly.
(b) In a second stage I transfer the 40 fully standards-compliant ePubs to the blank SD. Result: The thumbnails display, but with the "corruption" symptoms mentioned in the thread: no information displayed in the "info" page, wrong book opened when tapping on the thumbnail, etc.
(c) Given the circumstances, I do not attempt to transfer the "not fully standards-compliant" ePubs to the SD.

I've tried several other scenarios. For example, if a "brute force" loading of the T1 is attempted (trying to transfer, say, these 100 ePubs to the main memory and these 40 to the SD card in the same go with Calibre) the most likely result is that, apart from (of course) getting errors in the SD files, some of the files in the main memory will appear duplicated; that's why I tried a more gradual approach.

Oh, and (don't ask me why, but) when all these problems appear they can usually be solved deleting the "books.db" files and letting the T1 rebuild them
