Western Digital Elements External Hard Drive Disassembly
Hmm, maybe the SATA USB adapter broke when you opened up the drive. I don't have a problem connecting a 640 MB Hitachi or a 1TB Samsung drive to the adapter and both work without any issues.
Thank you for the details on how to open the box.
Thanks for the tip, Martin. I'll have to try again then.
I tried to put a WD10EADS in the case and it doesn't work for me. THe only difference between the drive it came with and this one is the size. Am I'm not doing something right?
I want to add that the WD10EADS works fine when I connect it directly to the computer as a regualr hard drive. Also the WD20EADS works fine when connected directly to the computer and when I reconnected it to the USB/SATA adapter so I know th adapter is fine. Since the WD20EADS came preformatted is there a certain way it was formatted to work in the Elements case?
I had the same problem that the USB adapter won't work with any other drive than the one that came with the enclosure. I think WD programmed the USB adapter that way. That's too bad.
Thanks for the quick reply Chieh. I don't know how Martin did it. Guess I'll have to buy a HD case for my WD10EADS. Also thanks for the great pictures on how to open it and showing what was inside. I didn't want to deal with the advance formatting of WD20EARS so this was a great way to get a WD20EADS.
Just purchased WD Elements 2TB from Mircocenter.Priced at $169.00 I paid $129.00 due to price matching with Newegg.Sales clerk didn't know RPM and cache.We checked web and couldn't find anything.I did a Google search at home and ran across your website.Thanks for the FYI...7200RPM - SATA - 32mb cache.I wonder why Western Digital is so secretive about disclosing information on there web site?
My only guess is that they don't want you to buy an external version just to pull out the drive . . .
I just got one of these from Newegg (109.99) and the instructions were superb. I was able to attach the usb to sata connector to multiple hard drives and it was fine. Just FYI
Thanks for the update, Chad. From your info, I'm guessing that there are different versions of the USB/SATA adapter for these external enclosures.
I was able to swap out the original hard drive with a Hitachi 1TB drive and it works fine just like any other external enclosure. You should change your article because it almost discouraged me trying out the swap.
bought this enclosure on ebay (without hdd) and was able to attach WD 1TB without any problem. It only took me 20 minutes to figure out how to open it. I'd rather have like 4 screws on the bottom or so.
my guess would be faulty SATA to USB adapter etc.
I picked up two of the 2TB units from Target, and they both had WD2001FASS drives in them. They're the WD Black series - 7200RPM, 64MB cache, SATA 300. Much better than the green series that came in the one in the article..
$69 per unit, and the WD2001FASS drive currently sells for $169 near my place :D
I tried my Barracuda 1.5 GB drive in the enclosure again. It still fails. When this drive is connected, the LED on the back flashes on and off. The drive also doesn't spin up.
The USB adapter board that I have in my possession has the following designations:
OASiS DESKTOP 1607P
When you report whether your board works with other hard drives, please provide the designations on your board for comparison. Thanks.
Same Here, My Oasis adapter is the same model. The drive works fine over internal SATA but once put into the case, it is found in disk management but doesn't show up in My Computer. I have tried different applications to format it inside of the USB case, but no luck. It says access denied!
Real shame, because I really like the way the enclosure is.
I also bought one of these at Target on Black Friday and found a WD2001FASS Black Edition drive inside. I hooked up my Seagate ST3500320AS to the USB-SATA adapter and it worked fine, however I also hooked up my WD1500ADFD Raptor and it gives me the drive is write protected error in Windows 7's disk management when I try to initialize it. I haven't tried my Maxtor 7L300S0 yet.
I opened up a 2TB drive i purchased from target during "Black Friday" for $69, and i was very happy to see a WD Caviar Black inside. And the adapter works with at least 2 of my other sata drives i have out.
OASiS DESKTOP 1607P
I have a 1TB model with an EADS drive and was able to swap it out with a Seagate LP 1TB drive.
Thanks for the guide Chieh Cheng. I had no luck swapping with a 1TB Samsing HD103UJ. The drive is recognised in Win 7 storage device manager however it is reported as requiring initialization. Any attempt to initialize does not work - write protected error message. The Sata to USB board inside is OASIS DESKTOP 1607P, REV.B 4060-705078-001. The original drive inside the enclosure was a WDC WD20EARS-00MVWB0. Using SIW - System Information for Windows (free version from http://www.gtopala.com ) I was able to tell the drive before opening it up.
Does anyone know where I can purchase the
Seperately? I have a damaged card and need to replace it. I have proprietary information on that drive and do not wish to send it RMA to Western Digital.
I just bought a new WD20EARS, hoping to use it in a 500GB enclosure I have. In a forum, opinions varied concerning my likely success, but one poster said he could sell me an empty WD Essentials 2TB enclosure cheap, and I soon decided (before my HD arrived) that this was a good idea. The enclosure and HD arrived yesterday and I figured out how to install the drive this morning and it's currently 63% formatted by one of my XP laptops. So, yes, it's possible to install another HD in one of these. I think probably any WD 2TB drive would work, however mine is advanced formet. I configured XP to use 4096kb allocation size (offered were DEFAULT, 512, 1024, 2048, 4096, 8192, 16k, 32k). I plan to run WD Align once formatting is complete and run tests on the drive to ensure it's fully functional.
I was able to install a 500GB Hitachi into the enclosure without a problem, maybe you guys should make sure your drives are formatted correctly before connecting them to the adapter?...
Thanks for sharing how to dismantle the case.
The Oasis desktop 1607P REV A 4060-705078-001 works with a WD1600YS

Good article. You can find videos on youtube to dismantle if you need a visual disassembly.
I have a
...and tried it with many different drives and found it works fine with some and not with other drives.
Looks like WD has messed around with the initialization of the SATA to USB adapter when powering up the drives.
Some drives would spin up, others would not.
Operational drives would work fine and disk managment would handle them no worries.
Thanks for your input, Bob. That really shed light on why all the boards have the same designation, but some drive works and some drives don't. I guess all the drives I tried with it do not work and made me think that this board won't work with any other drives. With your insight, I think I'll keep trying new drive as I get them and keep these boards as gadgets in my drawer.
First of all, thanks for all the info.
I recently bought one of these, which came with a WD20EARS.
Is the ROM made to work only with WD HDs? donno...
I just bought one, it also came with Oasis 1607P controller REV B 4060-705078-001 , and a WD20EARS.
Hello guys, i have a WD ELements with 1 TB and replaced the 1TB disk with a 500 GB one. It worked fine, and even my 160GB disk is recognized by the controller.
My model is a "Oasis Desktop 1607P" and the Metal clip reads:
I hope this helps you!
Greets from Germany, Michael
I tried with a Seagate barracuda 500GB
Hello, can someone with the OASiS DESKTOP 1607P REV B board tell me what is the model number of the 8-Pin IC located just behind the DC Jack?
The part number designation is U2.
It's too small for me to read. So I shot a photo of it with my camcorder and enlarged it on my computer. It helped slightly, but I still can't make out what it says. I've attached the image below. Maybe you can make out what it says.
My WD1.5TB external drive (with WD1501FASS Caviar Black) has Oasis Desktop 1607P USB/SATA board showing RevB 4060-705078-001.
The U2 chip is labeled -
Used old-skool magnifying glass! :-)
I have recently bought a 1.5To WD Hard drive WDBAAU0015HBK-EESN.
I think this USB2SATA adapter is not fully compatible and all functions are not implemented.
for the U2 Chip : mine is MSC 7101IDM 047G
The U2 chip looks to be a standard I2C EPROM chip. It might contain information on the drives it's supposed to connect, and that would mean the adapter is simply hard-coded to fail in case the drive's ID does not match the ID string programmed in the EPROM.
If someone could read out the EPROM we may be able to find out something more. I wouldn't be surprised if there was a string in there that reads "WD20EARS" with some kind of revision number. Which means the enclosure should be straightforward to hack to other drives just by reprogramming the EPROM to match the drive ID string.
U1: INIC-1607P - SATA to USB Bridge Controller IC - http://www.si-tech.co.jp/eng/v-ini.php
U4 is used as ROM for U1 and stores firmware for whole OASIS DESKTOP 1607P device. So probably here we have our problem. U4 is flash so it should be easy to reprogram it with some other firmware.
I inadvertently plugged my laptop power supply into my external drive and now the white light doesn't light up & the drive doesn't work. Is there any way I can use the above information to retrieve my data?
You can take out disk from that black box and use it as normal SATA HDD in Your computer. Or put it in another "SATA to USB" enclosure.
Someone much more intelligent than I am may be able to figure out my problem regarding the Oasis Desktop 1607P controller. I was helping a friend remove the virtual CD capabilities and hidden partition off his Toshiba and when I ran the removal tool (no longer on their site thankfully) , it affected my WD 3TB Elements drive. It wont even show up in the drive management connected to the sata to usb controller. So I popped it out and hooked it up and my data was gone. I stupidly ran testdisk to recover but it doesnt seem to support GPT partitions so I believe it screwed it up even more. It looks like it now had a MBR and is split into two partitions. I converted it back to GPT but I fear this screwed it up even more. I tried every data recovery prog I could find and they all found nothing but garbage. My question is, can I repair the firmware on this oasis desktop 1607p controller so I can hook the drive up via USB again?
Thanks to anyone who may have an answer/suggestion!
One of the things - if not the only one - which seems to keep drives from working in these enclosures is that the SATA/USB converter seems to do funny things with the drive geometry. Take a drive from an enclosure and attach it to SATA and it will work. Take a drive which has been partitioned through SATA and put it in the enclosure and...
EXT4-fs (sdb1): bad geometry: block count 244190000 exceeds size of device (244189944 blocks)
Hmmm, what happened? The drive is unchanged, attach it through SATA and it works as normal. Looking at the partition table when connected through USB shows the following:
Disk /dev/sdb: 1000.2 GB, 1000202043392 bytes
Device Boot Start End Blocks Id System
Indeed... a drive with 'total 1953519616 sectors' will not be able to hold a partition which ends at '1953520064'. When connected through SATA the same drive type shows up as:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
SATA: 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Someone stole a cylinder! Either the Oasis controller has an off-by-1 error somewhere, or it intentionally misreports the geometry for reasons unknown. Whatever the cause of this discrepancy, it means that partitions created on a 'native' SATA controller might end up being to large to work through the SATA/USB controller.
Given that I have enough backups of the data on the drive I decided to experiment a bit:
# resize2fs -f -p /dev/sdb1 244189944
# e2fsck -f /dev/sdb1
I then used fdisk to resize the partition (by first deleting it, setting the dos compatibility flag to allow partitions to start on sector 63, and finally creating a partition starting at sector 63 covering the whole disk). The end result is that the drive is now running in the enclosure with the original data on it.
TL,DR: the SATA/USB controller reports the drive geometry incorrectly - the number of cylinders is reduced by 1 leading to a reduction in size by (heads * sectors/track * 512) bytes. To get file systems covering the whole drive to work through it you'll have to reduce their size to get them to fit.

Thanks for this detailed insight, Frank. It'll come in handy when I mess with these USB/SATA adapters again.
OASiS DESKTOP 1607P with "Rev B" on the backside of PCB
i have a western digital desktop external hdd 1.5tb sata/32 mb cache any ways i have the same problem. my usb adapter plug on the board itself is about to fall off and not even had it bit almost 2 months does any one know where i could get a direct match of the adapter board that plugs to the sata plugs on the hdd and to the 2.0 usb and 12v 1.5amp power supplied plugs?? any info. would help
OASiS DESKTOP 1607P
I recently bought two Western Digital Elements 2T external hard drives in order to upgrade the 500G drives in my computer. The idea was to use the 500G's as external drives afterward.
Getting the 2T's to work in the computer was a snap but not so the 500G's in the cases. They didn't spin up and the leds flashed.
Google didn't help much but it did make me realize I am not the only one with this problem. That's why I'm sharing the solution I stumbled upon through trial and error:
Basically what I did was to put the HDD into another, non Oasis based, external enclosure. The computer picked it up as expected and I was able to do a low level format. I then took it out of the enclosure and reconnected it to the computer via the Oasis adapter. This time the drive registered and I was able to create a partition and NTFS format it.
The enclosure I used for the low level format is an earlier version of WD elements (the ones with the anodized aluminium case and rubber ends).
The software and the enclosure I used was just what happened to be around and I have no way of telling how critical it is for the fix to work.
The Oasis adapters are both Desktop 1607P rev B
Hope that is of use to someone.
Karel van der Walt
Thanks Karel for this glimpse of your insight. Maybe there is light at the end of the tunnel after all. I wonder if it has anything to do with a the earlier version of WD Element adapter you used. I will attempt to duplicate this process using a non-WD adapter when I get a chance.
thanks karel, hddguru's tool worked just fine for me; btw i was using a non Western Digital Adapter for the low level format
Sorry for my doublepost.
R63 on the Oasis Desktop 1607P is 4.7 Ω (= 4,7Ω).
My 2 TB Seagate harddisks don't work with the Oasis Desktop 1607P. The led is flashing and the drive is not spinning.
What is wrong with the drive being black?
for the sake of the article, the HD model WD20EADS that comes inside it is NOT 7200. It is 5400rpm green version.
The card seems to work for all three of my 2.5 laptop SATA drives (Seagate Momentus 7200.3 320GB, Fujitsu 80GB, and Hitachi 160GB from PS3), so I believe it not an issue with firmware or WD trying to block this card from servicing other manufacturers, but an issue of insufficient power. The card was designed with the 3.5" Green line of WD drives in mind which only consume 5W at read/write whereas the 3.5" Black line of WD drives consume 8W at idle and nearly 11W at read/write.
That's a good point, Digital Treesloth. I don't know why I've never thought of that as a possibility.
I bought 3 of those HDD cases from a guy who had used the original WC disks. I put in seagate pipeline HD2 disks, but they wouldn't spin. I used a soldering iron to connect +12 and +5 volt from the 1607 board direct to the sata power connector. In case of the +5 volt you only need a drop of solder to connect it to the coil output (remove solderscreen first). +12 Volt goes direct to adapter input connector. They work fine now!
Thank you so much for sharing the solution!
Writing Zeroes (connected to internal SATA) to the entire disk solved my problem!
I used "Data Lifeguard Diagnostic für Windows" provided by Western Digital (http://support.wdc.com/product/download.asp?groupid=605&sid= . . .
After that, the disk is (re-)usable inside the case and partitioning and formating works (tested on Win XP Pro & Ubuntu 12.04)
I have bought a WD Enclosure and a 500GB SATA3 WD drive made in 2013.
But I had a lot older 500GB SATA2 WD drive made in 2010 and with that drive the enclosure works fine.
I don't know why the older one works fine and the newer one doesn't but at least I'm happy that one of them works just fine.
I bought WD Elements 3TB and replaced with 500G.
I could not partition and format in Windows. I loaded it on Mac but it only appeared as 3TB and could not do anything.
Hope this helps anyone.
I am so glad I stumbled into this discussion because I almost gave up hope.
