4GB stick. Nothing in it (removed all anime vids and mp3s) except for Fast Loader, UMD Ripper, Dax Dumper, FileAssistant, DevHook 0.44, Bookr and PePViewer. So yeah, working with around 3GB+ of free space at the time of dumping.

Thanks for the tip. It's USB Special System Storage, but I found it just fine searching the
PSP applications listing for the word storage.
Will try it now and report what happens. I'm thinking there might be a scratch somewhere but my eyes are too bad to see it...
Tried ripping to HDD via USB Special System Storage. Reading still failed at sector 418304 of 854605. I've tried copying the ISO directly, mounting via Daemon Tools then copying individual files (using Windows Explorer), mounting then extracting files via ISOBuster, mounting then ripping image via UltraISO, opening image via UltraISO and converting to other image format, but nada. I've isolated the problem to around 88% of TKPDATA0.BIN. I have no idea if only a few sectors (those immediately surrounding 418304) are unreadable or if the failure's up to the end of the file as UMD reading stops as soon as it encounters an error. Sectors 442560-854605 are fine as I was able to extract TKPDATA1.BIN without any problems.
Is there maybe an ARccOS equivalent for the UMD? Or should I just use that BestBuy gift card (and maybe just add a little more cash) to buy a replacement?
Edit: Just looked at the ripkits. Apparently, TKPDATA0.BIN contains just the videos and I can have a perfectly working ISO even without it. LoL, I would've ripped it out when creating the ISO, anyways, so the ISO can fit into the free space on my brother's 2GB memstick. Thanks to sticky for the heads up. I wouldn't have been able to extract TKPDATA1.BIN without the advice. Or maybe I would have eventually but only after a ton of headaches on my part.
