Problem with Mybook model WD10000H1U-00 and Windows7 64 bits


Hi all

Excusing the Google translation.

I have a problem with a “Mybook” a 1TB model WD10000H1U-00, when attempting to back up from a DELL PRECISION 630 from Windows7 64bit gives me error 0x80070005, also will not let me copy files larger than 4 GB, the system crashes.

I have another USB drive LACIE 500GB and I have these problems.

I worked with the same computer and Windows XP 32bit perfectly all this has begun to change Windows7.

I’ve included the patch KB976972-x64 but not fix the problem.

Greetings and thanks for your help.


Are your external drives formatted as FAT32?

FAT32 has a 4GB limit for file sizes.


The disk is formatted as NTFS and optimize for performance.
