Hi guys, I am experiencing issues with a Seagate Expansion Desktop, that is attached to my RT-56U via usb. I am currently in the process of backing up my entire DVD collection to HD, but every time I unplug my external disk from the RT-56U and plug it into my laptop USB, Windows 7 tells me that something isn't right with the external drive and that it has to be fixed. As a result, I am losing one or several of the DVDs I have copied and can start over again. Here are the exact specs: - The Seagate is a 3T drive, formatted NTFS. - The RT-56U is running Padavan's custom firmware. - The computer is running Windows 7 64bit. My main issue is that I really have no clue which tree to bark up at. Is this an issue with the hard drive, or is the problem with the router that is writing to the disk? And: I also don't know if this issue already occurs while the disc is still plugged in with the RT-N56U, or if I'm deliberately causing it by unplugging the drive. It *appears* like all is fine when the drive is still connected to the router, and after connecting it to my computer, it is not (directories missing before I start the repair process). When I manually start chkdsk, it will list most of the directories that aren't showing up, but after the repair process they are gone anyway. It also appears like the issues are only with the more recent folders I have copied. So let's say I've just run chkdsk, couple of folders lost, but the remainder on the disk is "safe" - if I repeat this the next day, there might be issues with some of the newer folders, but not with the old ones. (And note that "new" is relative and also applies to any DVDs I might have copied the night before.) Any pointers, ideas or suggestions would be greatly appreciated!
