PRS-600 Memory card transfers

TimNeo · 12-11-2009, 06:55 AM

Hi, getting a PRS-600 at Christmas

Can I load books to an SDHC card and transfer them accross to internal memory & delete read books?

no. you can load them onto the card and then read them on your 600. but using just the 600 there is no way to transfer books between internal memory and the card.

you can also hook the 600 up, with a card in it, and transfer books to internal or the card, your choice.

bah, well thanks for that. I'm generally worried about the amount of battery problems the SD card reader gives the sony reader - I'm getting one for Christmas with a 16GB SD card and was hoping that I could take my entire library with me (some 14GB of books) and just load a couple over when I need 'em being away from a PC. It'll just need to be more careful what I load, just keep it to old favorites and a few new ones.

Why didn't they put in a gb or 2?!

Battery problems? An SD card draws very little power. About the same as you'd expect from the same amount of space built into the device.

I still get about 2 weeks on my 505 with a 16GB SDHC card in it.

The internal memory is sufficient to comfortably hold many, many hundreds of books. That's enough for most people.

The limiting factor is the fact that, whenever you insert a memory card, the Reader does a "scan" of the library to see what's there. This can take literally HOURS when you have multiple GB of books. It's really not practical to have more than a few hundred at a time.

My understanding is that the scan only takes place when new content that doesn't have the data cached is inserted. If you load it up on your machine using Sony's software (if you can, that is, Linux users are left out), or let it cache everything before you leave, then it will just work while you are away.

This is how it worked on both my 505 and 700.

Good stuff, I've been reading a lot about battery issues on here and the consensus seemed to be it was to do with the SD card.

Still a shame they don't include a couple of gig.

They don't probably because of the scan. I've managed to cram about 250 books into the on-board memory, certainly more than I can read at one time. The scan takes about a minute. For the people with 8G+ cards, what are you keeping on them? I'd hope not a few thousand books, your scans must take a looong time.

Oh, and it does a scan after I've attached it to a computer (even if I didn't change anything, just to charge) or after a complete power down and start up (not sleep mode). So I'd say a scan is a fairly common occurrence unless you plan on loading it up once, never do a full power-down (only sleep) and only using an AC adapter to charge it. Even then you're going to trigger a scan once in a while I bet. A 16G card with thousands of books on it is going to be painful.

I find on my 600 that it does a scan whenever I disconnect the Sony from the eBook Library, regardless of whether anything's changed.

I would expect a short check to see if the cache matches up with the content, but it should be pretty short compared to a real scan. All Sony readers do this part. If the content hasn't changed, and the scans still take hours rather than less than a minute, it sounds like there might be a bug there.

That said, my library is only a couple hundred books or so right now. I just have some big ones in the 30MB range that got me to buy a 16gb card.

you have to remember too, we're dealing with a 532MHz Freescale CPU here reading flash RAM (of varying speeds depending on your card). hardly the fastest thing out there.
