WD MyPassport 2TB (Mac OS Extended formatted), connected to WD MyCloud 4TB USB port.
Every time i copy something to MyPassport, and disconnect the drive, disk verify in OS X Mavericks Disk Utility reports several errors, for example:
Incorrect number of extended attributes(It should be 4717 instead of 4715)
Invalid leaf record count(It should be 5433 instead of 5431)
Overlapped extent allocation (id = 39452)
Volume bitmap needs minor repair for under-allocation
Invalid volume free block count(It should be 1335978 instead of 1335980)
The volume MyPassport was found corrupt and needs to be repaired
After Repair Disk is run, several files are stored in “DamagedFiles” folder on MyPassport, and these files are damaged!!!
Also tried with different USB disk, same problem!!!
I am really dissapointed with MyCloud NAS, worst piece of hardware i bought for a long time.
