After saving more than 9400 images in my photos album, of my iPod Touch 3G, it is corrupted off a sudden!
In fact, it is not all of a sudden. It started getting sluggish when the album has enough number of images (cannot even remember since how many), each time when I try to view the images in the photos album, after saving some images from the internet, it starts "rebuilding the library", and also "updating library, this may take a few minutes". The more images there are, the longer time it takes before I can view the new images, or the whole album.
Finally, the crises came when there are over 9500 (not sure of the exact number though) images, it starts this "rebuilding the library", and also displaying "updating library, this may take a few minutes" at the same time. But as soon it is over, and the album is viewed, the same process starts again. By the way, it is not a few minutes each time it tries, maybe more than 10, but never cared to time it.
After searching around, found this iPhone PC Suite. This is really an angel sent from heaven! Some how the version I downloaded is in Chinese, but it works perfectly. I can view the contents of the photo album. The only thing I needed to do is to delete some of the images, actually moved to other places. After that, the iPod started the same ritual again. But this time the album can be viewed! The only change is that the icon of the album is changed.
By the way, according to "iPhoto 6 and later: Rebuilding the iPhoto library" in Apple's support page, rebuilding the library may resolve issues such as the library appearing to be unreadable, missing photos, or other issues related to reading the iPhoto library structure. My guess is that "other issues" include increase of large number of photos (images). Although the detailed specification is not clear, my experiences show that a few dozen more new images can cause it to start rebuilding the library.
According to the page above, it looks like Apple's iPhoto (part of iLife) can also solve this problem. But, the bad news is that it only works on Mac! And what's worse, it is not free.
Upon more search, found out that this "updating library" happens after synchronization with iTune too. Somebody reported that all the music was gone. By somebody's effort, it showed that it happens after the number of songs increases to certain range. For somebody, it disappears after "rebooting" the device, and restore with iTunes. In fact, the "lost" music had not been lost. It should be just the corruption of iPhod's data or file structure. The files are there, just not accessible by iOs.
iPhoneやiPod Touchの写真（Albumに保存されている画像）が突然見れなくなることはありませんか。実際iPod Touchで9400枚以上の画像を保存してから、Albumは全く見られなくなりました。救済方法はいくつあるようですが、iPhone PC Suiteは一番簡単でした。どうも見られなくなる原因はOSの画像・フォトライブラリの管理ソフトにバグがあるように思います。その根拠は、写真・画像の数が千枚になると、新規に複数の写真を保存するたびに、画像の管理情報を再構築するように見えて、数分にわたって、システムが固まってしまいます。処理中のメッセージは表示されますが、時間がかかり過ぎて、壊れてしまっているのではないかと心配させられます。
因みにiPhotoでも問題回避できるそうですが、Macを持っていないので、実証できていません。
