Seeking help for combining multiple hard drives

post #1 of 35
Thread Starter 
I am considering buying an oppo 93 with only two inputs.

Here is my current setup.
I have two Western Digital WD Elements 2 TB USB 2.0 Desktop External Hard Drives - (usb). 2TB. These are in sealed black boxes. Not sure what the drive is, inside them.

Also, I have two 1.5 TB hard drives (inside my xtreamer pro media player, which). I can combine them into one 3 tb external hard drive.

How do I connect more than two usb drives to a unit which has only two usb drives?

Is there a USB input selector with IR control, so that I can add multiple drives?

Also, another question to the computer experts.

Whats the best way to transfer large data (like 1.5 TB from one hard drive to another)?

I have linux and xp computers. I can use either operating system.

thanks

You didn't really need to start yet another thread, but there are many many USB hubs that wi allow you to attach as many hard drives as you want to the oppo. Alternatively, you could use a mediasonic 4 bay enclosure with one USB cable as well and the oppo will see and read each disc individually if you have the setting correct.
I would post some links but relying from my phone is painful enough as it is...

I've never owned an Oppo, but like the previous poster said, a USB hub should allow it to see all 4 drives separately just like it would on a computer. No need for any selector, just use the OSD to select which drive you want. I'd look for a hub that doesn't require an external power supply to save on cable clutter, but some devices don't play nicely with them. Good luck!

streamerlover,
Reason I started a separate thread is because I don't like digressing from the posted topic.
Anyway..
Any usb hub will work? I mean.. the hubs that are normally used with computers - they will work?

Are you using it with an OPPO? I want to make sure that it would be recognized by the oppo. Frankly, I would rather use the USB hub, if that would work.

Nope, I used it with a PCH-A300. I think the USB hub will be the cheaper route.

could not have said it better. I have had no problems with the three USB hubs I used on my oppo, ranging from a cheap $1.99 one to a $22 powered one. I have also used the firstdevice gusgus posted and it worked fine... the second one he posted will NOT work as the oppo does not have the port multiplier capability. stick with USB. for trouble free operation. the esata can be finicky...

Currently, I have two 2TB internal Hard drives WD20EARS
and TWO Western Digital WD Elements 2 TB USB 2.0 Desktop EXTERNAL Hard Drives
All these have movies in .iso files, stored in them. The plan is to access the .iso files through the OPPO. Yes, it is playing .ISO files. I did test it.

Based on the suggestion of gusgus and streamer lover, I bought the Mediasonic below.

http://www.newegg.com/Product/Product.aspx?Item=N82E16816322006
I thought I would connect, using esata cable to the oppo. Is this wise? Or shall I use USB? Mediasonic does have usb 3.0 and also esata output

I need help in setting up the Raid. I assume I would need to set it up with Raid 0 (Spanning)?

I am going to remove the two hard drives from the two external units and put all four hard drives into the mediasonic unit.

I want to use the front panel of the mediasonic to set up the raid 0.
Before I do so, I am seeking suggestions so that I don't end up losing any of the data.

Thank you.

These large drives have a relatively high failure rate. Newegg shows a 15~25% one-egg rating for premature failure.
I own a computer business, and every Caviar Green 2TB in service fails within 3 years.
I just lost one of a RAID1 pair last week and it was less than 2 years old.
If you are not backed up, or in a RAID or RAIDZ configuration, your data is gone.

A quality, powered USB 2.0 hub is the ticket.
I have a few Belkin powered hubs for this purpose. They seem to last longer than the cheap brands.

I use my SATA drives in Venus chassis.
These have either USB or eSATA connections.
The eSATA connection is much faster. You will need this for large transfers.

When I offloaded the data from my broken RAID1 volume, I connected another 2TB drive directly to an open SATA port.
It still took 47 Forevers to migrate 1.8 TB of data at full SATA-II speed. USB will be much slower.

Its too late now.. Already I have the western digital drives. I don't want to buy new drives etc. now. I will take a chance. I still have my DVD collection and my home movie collection but it would be a lot of work to re-transfer them.
I need help with the Raid 0 for spanning. I won't be transfering any data.
I assume that once the drives are in a raid, they can't be separated and used separately, even with raid 0 spanning?

guess what. One drive got corrupted -
Error : the hard disk structure is corrupted and unreadable

as I was swapping between the two identical drives.. I was not unmounting the drive, under windows xp - do I have to?

. fortunately, i have a back up of that home video drive..
question: For Raid 0 configuration, can I buy a different brand drive? If not western digital, which brand.
Can I add a 3TB drive to the Raid configuration? Like three 2TB drives and one 3TB drive? Or may be even 4TB?

First of all, you can NOT use Esata. The Oppo does NOT have the required hardware to read more than the first drive in the enclosure. You will have to use the usb connection which is more than fast enough and is not as finnicky as the Esata.
And I am trying to remember if the enclosure can even read each drive separately....If not, then you are going to have another issue. I will take a look at it in a bit and report back...
post #14 of 35
how do you know the drive totally failed. there are some tools to try if only the Master Boot Record got screwed up. Has happened to me once or twice..
post #15 of 35
I do have an Oppo 93 and Mediasonic ProBox 4 Bay Enclosure (HF2-SU3S2) with 4x WD Caviar Green 2 TB Desktop Hard Drive (WD20EARX) interconnected via USB3 cable and it works perfectly. Oppo is only "USB2" capable but I use the same cable for connecting the Mediasonic to my laptop which has USB3 so I can transfer huge files quickly. I found eSATA unreliable. Oppo sees all four drives as separate disks.

You, my friend, have a different box than what the op bought. Here is a link for the current mediasonic box line up. Your box is what the OP should have bought if he wants to read each drive separately. The raid box is going to be problematic to set up as he already has data on the drives...
http://ain.mediasonic.ca/store/index.php?cPath=71&osCsid=51b19a5aebb06ac273c26444929b458c

Your box is HF2 which is good for seeing each drive separately
His box is HFR2 which is NOT good for seeing each drive separately

Yes, I noticed...and I was also looking into RAID-capable Mediasonic but I learned that Oppo will not see RAID-managed disks anyway, so I "mirror" some drives "manually" to portable external backup drives.

You are correct. it did not fail. Something got messed up - as I was swapping cables between the two boxes. Do you know any recovery tools. I have one important file on it that I don't have back up of.

Gusgus, I ordered exactly what you suggested. Streamerlover says it won't work. Did you use it with an OPPO?
I guess I have to repack it and return it. I dislike returning. Mainly because I am wasting money for someone else..
I knew that I have no knowledge about these raid units.. I had hoped to be steered right..
Oh well.. I guess I would return it and try the usb hub route..

Sorry, but I've never owned an Oppo, and probably never will. I had the Mediasonic with the PCH-A300 and Dune prior to selling it and building my unRaid server.
post #21 of 35
You could get that box to work with the oppo but the problem is that it will reformat all of your hard drives. As you don't have any extra hard drives that would be the problem.
I use Easeus Data Recovery Software as I have had good luck with it but there are many many more out there. I don't know that much about them so I stick with what I know.
If you are looking to see each drive individually I have an HF2-su2s2 I am no longer using and could sell it to you for a fair price. I KNOW this one works as I had it hooked up to my oppo!

Hook it to the PC and go to a command window and run "X: chkdsk" on it first. See what it reports back, my guess is volume bitmap error if the drive shows up but you don't actually see any data on it, then run "X: chkdsk /f" Replace "X" with the actual drive letter windows assigns to it.

tried it.. it did not work. Nothing happened when I did "j: chkdsk /f"
I will buy a data recovery software.. Know any good values?
post #24 of 35
You are now working the high wire without a safety net.
eek.gif

CHKDSK, etc, can/will get you into all sorts of hassle (read: bye bye data).
First, push back far enough so you can not reach the keyboard.
Nobody is bleeding or dying on the side of the road, so you can take time to develop a plan.

If you have critical data on that disk, you have to take steps to make a copy you can restore, should your efforts go South.
I use Ghost Corporate, to make a forensic image (sector by sector).
This is your safety net.

Next, I use OnTrack Professional data recovery.
This is a pricey piece of software, and not for the one-off guy.

If you don't mind the considerable expense, you can contract with OnTrac for a data recovery.
If the drive is mechanically sound, they install an Active-X control on your machine and come over the Internet to work their magic.
Their not-for-sale tools are FAR more comprehensive than the (expensive) tool I bought from them, but they get the job done.

thank you all for your advice.. Fortunately, I have found a backup.
I will reformat and use the external drive. I think it got corrupted, as I kept swapping cables between two identical external drives..
I will try the USB hub route and see if that would work.
The raid does not seem convenient at this time. Perhaps it might have worked, if I were starting out but since I already have data, it's too risky to try and raid them. Another disc could get corrupted and I don't have sufficient extra drives, to backup 5 TB
post #26 of 35
Hmm... are you willing to throw away 2TB of data when one of those disks goes bad?

I'm not being argumentative here, but speaking from experience.
In my computer business, nearly every 2TB disk (Caviar Green) has gone bad within 2 years.
I don't dare run any of these as non-RAID for fear of data loss.

My office backup server runs a pair of these in RAID1.
One just died. Dead. Gone. When plugged in, the system cannot boot.

Knowing both 2TB came from the same batch, production date, and close in serial number range, I figure #2 is ready to die very soon.
I made a copy of #2 to a third and separate 2TB disk for safe keeping.
This still took a very long time, plugged directly into another SATA port on the same server.

Rebuilding a fully populated RAID1 array with 2TB media takes a very long time.
It is much faster for me to wipe #2, replace the dead drive, recreate RAID1, then restore from the third disk.
It best, this is a giant hassle. At worst case, kiss off 2TB of data.

I'm prototyping NAS4Free and RAIDZ-2 in a VM right now.
This offers additional security over RAID1 or RAID5.
The point of all this is, big data = big problems when something goes awry. Plan for it.

streamerlover,
My oppo is not recognizing usb drives.
Some times it does and other times it does not.
It recognized a non powered (cheap) hub and two drives.
Later, I pulled one drive out.
now it does not recognize the single drive.
i removed the hub and it still does not recognize the single drive.
I did power it down and turned it back on.. I had even pulled the back plug out.
It is the same drive, which worked earlier.
suggestions?
thanks.

Oppo corrupted another drive!
I lost one drive yesterday and another drive today!
I have been swapping usb drives back and forth on the oppo.
Some how, oppo is corrupting the drive - tables?
I guess I should not be swapping - I should power OPPO down before I swap the drives?

I hot swap 2 tb drives all the time and never once had an issue. If I have swapped drives less than 50 times I would be surprised and never once had an issue. I think the issue lies with your drives or maybe the controller used by the external controller?
For the longest time I was using one of those "toaster" style docks and kept swapping them out. Never once a problem..
Try hooking the drive back up to your computer and see what it shows...

You might have a point about the controller. I am now going to open the drive and put it in a different controller and then report back to you.

I did hook it up to a linux and a windowx xp computer. Neither could read the disc anymore.
error message "The file or directory is corrupted and is unreadable"

I did a quickformat on the previous drive and recopied my files and it works fine now.
I am 100% sure that it's the oppo. This is the second drive in 2 days.
I guess I have to buy the Dune.. Know anyone with a used Dune?

The oppo is certainly a great player.. The sound quality was clearly superior - even without A/B testing.
I am not so sure about the picture quality, yet. I need to get two identical BD discs and do a/b switching with my panasonic bd
