I have a WD My Passport Essential 500 GB 2.5" (Model WD5000MES-00 4309A / R/N: B8B) I bought 1 year ago (May 2009). It was working flawlessly with 180 ISOs on it. At that time I had system menu 3.2U + USB Loader GX + Waninkoko cIOS (rev 10 or 13 I would say). Then the WBFS partition got messed up and I had to re-formatted it and load the ISOs back... again, all continue ok.
Then I've upgraded my sys menu to 4.2U + cIOS rev 17 and most of the ISOs stopped working. They start to load, and then get locked or black screen... Some ISOs still work, as for example Crash 2008, Speed Racer. But all the Lego ones stopped working (and those are the ones kids like most)
So in order to eliminate some variables, I got a SanDisk 16GB (cruzer mini) pen drive and loaded some ISOs on it:
* Lego Batman, Lego Star Wars and Lego Indiana Jones 2, My Syms - NTSC-U
* Go West - PAL
To my surprise, all games loaded fine with no errors. Game play was smooth and continues without any lock/black screen.
Then I've reformated my WD drive, created the WBFS partition and loaded the same ISOs I had on the pen drive. The results were:
* Lego Batman - Could see the initial screens before the main menu (warning/caution screen, advertisment screen). But before see the main menu, got the black screen of death.
* Go West - Could see the warning/caution screen, main menu and then locked. Another time I could reach the main menu and started playing, but then it locked.
* Lego Star Wars - Couldn't see the main menu screen at all.
* Lego Indiana Jones: The Original Adventures - I could reach the main menu, but when trying to load/create a game it locked.
So I was thinking if that could be spin down issues... it happens before 2, 3 minutes. And why did it worked fine almost 1 year ago? Are you aware of any change on sys menu 4.2, cIOS, USB Loader that could affect this? I don't think so.
I've done some tests already on the HDD like chkdsk, GParted check on linux and they didn't report any errors. Now I'm running HDDScan (freeware). Initial read test was fine with no error, and I'm doing what they call a butterfly read and it's still running. The HDD seams healhty (no weird sounds, clicks, etc) and I'm almost sure it doesn't have physycal issues.
Pen drive continues working fine with NO ERROR still. No locking, black screen, etc... for PAL, NTSC, all fine.
Could you guys recommend anything? About crack opening it and hook it to a SATA mobo straight I think I can't do that cause of my hardware revision (B8B) right? I think this one has the USB controller tied to the HDD in a way we can't remove it.
I'm looking forward any feedback... (my kidos too)
