ppg113 thank you for your feedback BUT that diagnostic tool is for this model EXTERNAL drive, so if WD tells me there is a problem i will believe them.
2nd this external drive DOES NOT have an alternate power supply.
@ pcbugfixer the missing icon isn't why i think the Device is messed up its the fact that every time i plug it on my Vista machine i get, a notification about the Drive needing to be checked for errors, and the fact that 46 files were damaged, Also windows able to back up the HDD
with normal copy paste, i had to use "Unstoppable Copier" (lost the log but there were a few errors and skipped files)
i tried the WD diagnostic as shown above and nothing worked (even the External USB/FireWire Fat32 Formatting Utility) wasn't working (because of a "11-Cable Test::Read diagnostics sector error" error).
I ended up using widows format utility, and i still got the check disk message from windows at that point I ran the External USB formatting utility and the drives seems to be working properly again.
but im still getting the 11-Cable Test::Read diagnostics sector error message (i tried different cables)
I probably should have mentioned this before but, when i check the SMART disk information, it shows 1 error (still does after all the formatting): Raw read error rate
Edit: this device was bought from the US (I live in Lebanon) so warranty wont help I guess.
