My Cloud: 6TB. (new April 5th).
Updated to latest Firware: v04.01.03-421.
On Internal HD, runs as expected. No issues.
However, with extranal UB 3.0 drive, (3.0 cable) all sorts of problems.
Trying to connect a Fantom Drive 4TB (USB 3).
Drive runs fine when connected direct to PC. No issues. Reads/writes, recognised each time connceted, Unmounts without issue. (NTFS connected to Windows 7 PC).
Problems start when connecting it to the WD “My Cloud”.
(1) MY Cloud typically cannot recognise the USB drive.
(2) If the drive is connected to the PC, Mounted, then dismounted, then MY Cloud can then see it when connected.
(3) If “My Cloud” dismounts the USB drive, or is re-booted, thereafter, it cannot see the USB device, untill the drive is connected back to the PC, Mounted, and he dismounted. - The reconnecting it back to "My Cloud’, it see it (untill a re-boot or dismount).
–Yes, sfter dismount, I am unplugging the USB drive, waiting 10 secnds, and the re-connecting it, to attempt a re-mount.
When it is mounted, transferred a few Gigs of data to the USB drive, over the network.
Half way through, USB drive errors.
When connected back to th PC, drive had errors in MFT !!! Needed to run chkdsk/F to fix.
(a) may have issues with Big Drives ?
(b) Cannot sucessfully dismount the USB drive, and leaves it in a state where it cannot connect back to My Cloud (although can connect to a Windows 7 Machine) …
© My Cloud corrupts the USB drives MFT, making it un-usable, till repaired on a PC.
SOMETHING IS NOT RIGHT !!!
Does not give any confidence to using MY Cloud + USB drive as a backup solution – it needs a backup itself !!
(a) My Cloud needs better USB support.
(b) My Cloud needs STABLE Usb operation… without corrupting the ext USB drive !!
(Currenyly NOT HAPPY with My Cloud --)
