In Reply to: RE: OPPO 105 - need to format SSD - but which format? posted by stehno on February 03, 2015 at 00:40:36
So here's the problem. I think.
My particular SSD is a 3-year 240GB OCZ SATA III drive.
My external passive (no AC) drive case is a USB 3.0 capability. It does not specify 2.0.
The disk activity light in the ext. case was obnoxiously bright. So I disabled it thinking that might free up just enough USB voltage that could now be used by the SSD. This actually made matters worse.
I then tried a USB 2.0 cloning cable and that seems to work well.
I also tried a 10-year old 5.25" 200GB external HDD active (requires AC) and that too works well.
So my guess is the problem with using the OPPO's USB 2.0 ports and external USB drives has more to do with the use of USB 3.0 at the external case.
Anyway, thanks everybody for your suggestions.

Thanks for the note.
I've not checked the specs on my OCZ SSD. I bought 3 OCZ drives about 3 years ago and then discovered a year later that OCZ had some fairly serious quality issues. But I can't say I've experienced any.
But perhaps one of those quality issues is this SSD requires maybe a tad more power than the usual?
Someday I'll purchase a larger SSD by another mfg'er and I'll be mindful of the current drawing specs.
I was surprised that disabling the very bright ext. case light made matters worse.
Anyway, I just purchased on eBay a 2.0 ext SSD enclosure so we'll see if that works with this drive next week sometime.

Personnally I would not put any beleif upon the lack of power supply, as a SSD has lower requirements
While not likely the cause of his problems, testing for this possibility is simple enough with the $5 Y cable I mentioned. Some SSDs can consume more power than the 5v 1000mA available via the Oppo USB port.
Abe, just wanted to drop you (and the others) a note that today I received my external SSD case for USB 2.0 only and it works with the same SSD drive without issue.
So it seems that it was my external case with USB 3.0 only interface that was the cause and/or its voltage requirements.
I also received a Y-USB cable that someday I'll try with the external USB 3.0 only case and my guess that too will work but I'll save that for another time.
Thanks again for your help here.
And thanks for dropping us the note to let us know.
Thanks, Abe and Lesage.
Abe, I've got a USB 2.0 only ext drive case enroute and comes with a Y USB cable.
So I'll be able to confirm the power thing.
At present, the same SSD is working with my USB 2.0 disk duplicator cable.
I'll post what happens. Thanks again for working with me here.

- Supported USB drives can be formatted with the FAT (File Allocation Table), FAT32 or NTFS (New Technology File System) file system.
- The BDP-105 is equipped with three USB ports: one on the front panel and two on the back. You may use any of the available USB ports to plug in a USB drive.
- The USB ports are rated to provide a maximum of 5V, 1000mA power to the USB drive. It is sufficient for USB thumb drives and flash memory card readers, but may not be sufficient for USB hard disks. It is recommended to check with your drive manufacturer for power requirements, or use an external power supply.
