Copying iPhoto library to external drive - errors, corrupt disk
Hi -
I've been trying to copy my 35Gb iPhoto library to an external flash drive so that I can have it in portable form (it's outgrown my MacBook Air); every time I try to copy it, I end up with an error message and a corrupt flash drive. Here's what I tried doing:
1. Rebuilt my iPhoto library using iPhoto Library Manager (this is because I had tried to copy the Library before and there were problems with the file, so I thought I should start with a freshly rebuilt version). After testing it, Library seemed to be functioning normally.
2. Formatted my Centon 128Gb flash drive to Mac OS extended journaled. Check via Disk Utility that drive is normal. Dragged iPhoto library over to flash drive to copy. Took overnight (about 13 hours) to copy iPhoto library 😮
3. Checked on progress in the morning and found this message:
The Finder can’t complete the operation because some data in “iPhoto Library 20120531(rebuilt20121006).photolibrary” can’t be read or written.
(Error code -36)
This was the same message I had gotten in previous tries.
4. The Centon 128Gb flash drive was no longer visible on the desktop, and when I launched Disk Utility it was not mounted and not visible. I removed the flash drive from the Mac and reconnected it. Disk Utility then recognized it, but upon verifying the flash drive I got this message:

5. I then reformatted the flash drive and tried to verify again (both the volume and the disk). I got this message when verifying the disk:

7. It took several tries to get the flash drive reformatted and back to normal status (i.e. no problems showing up in Disk Utility). FYI, in a previous attempt, I rendered another of these Centon USB flash drives completely useless and had to return it to the company. No idea what to do next. Can anyone tell me what exactly is going on here, and why can't I copy my iPhoto library to this disk without corrupting it?
