I am running TI 2009 on Vista 32 bit SP 1 on a laptop with 2 internal drives and trying to backup to a western digital my book 1 TB drive on usb 2.0. Each time I run it, it gets thru with step 1 of 4 and then as it begins 2 of 4, it gets an error that operation failed. Operation with partition "3-0" was terminated. Details: <indent>Read error (0x70003) Tag = 0x2CBDD167CBCA94F3 Snapshot read failed. (0x10C45A) Tag = 0x14181C22EF45AD30 The parameter is incorrect (0xFFF0) code = 80070057) Tag = 0xBD28FDBD64EDB8B9</indent> I have ran chkdsk and even reformatted the external drive. I have also tried another external my book drive and it gets the same error. I have the latest build of TI (9709). I have looked on this forum and tried some other suggestions (turn off power saving, make sure drive caching is on, turn off system restore points), but nothing has helped. Does anyone have some things for me to try so that I can backup?
