I assume it waits to synchronize. Some file systems do that in the
background. Probably matters if some applications use fs. I'm not
sure how fat/vfat/ntfs knows when it's clean and when corrupted.

Original poster could shed more light into the topic. My bet is that
everything works fine, so no need to post further.

Thumbs up The Fix

To follow up on my last post, after I ran CHKDSK with the /F switch, the directories were readable and all was fine. But when I unplugged it, it tried to synchronize and still found no books, and when I plugged it back into the computer, it was once again "corrupt and unreadable."

It eventually dawned on me that in its attempts to synchronize, it was corrupting itself. So I ran CHKDSK /F again, then went into the directory, backed up all my ebooks and deleted every ebook file from the e-reader, including the ones in the Digital Editions directory. Once I'd done that, I ran Kobo Desktop, and it started downloading the new firmware upgrade, so that was a good sign.

After the upgrade was done, the reader was working but still had no books on it, so I had to figure out how to get the 100 preloaded books back on. Happily, that solution was available right on this forum: http://www.mobileread.com/forums/sho...7&postcount=12 (thanks Sameer). So I followed those instructions, and then all my books were back, and I was very happy--and tired, because it was 1:30 in the morning.

It doesn't have anything to do with whether or not the desktop was installed.
Quite right that I had not done anything wrong when it first gave me the message. I hadn't unplugged it yet so obviously what went wrong happened before that.

Normally it wouldn't be a problem that the desktop app was not installed, but that was the day a new firmware upgrade came out. Coincidence? I think not. Maybe the reader has a mechanism that checks for upgrades, and if the desktop app isn't installed it buggers things up.

Could you repeat once more exact steps you took?

Hm! I doubt. It should be aware of internet protocols and has it's own
ip address. And to know gateway address. Then to start client to connect
to kobo server. I assume desktop exists to unload reader of those tasks.
At least, slim chances. Someone would notice it on the sd card image or
using the device.

It's a write-caching option, I believe Microsoft has now defaulted to leaving write-caching turned off for any removal drive.
