Question about Western Digital New - Caviar Blue Wd3200aakx 320 Gb 3.5" Internal Hard Drive - 20 Pack - Dn1649

Open Question

Acomdata 509 not recognized by any of 4 different computers

Acomdata (Model 509) with WD 1600 AAJB drives installed. System: Dell Optiplex 740 with Windows XP-Home, Acomdata driver installed. Objective: to format these brand new IDE/PATA drives 1. Drive configured as Master, Master with Slave and Slave: the only evidence of movement of disk (Pink light) was when installed as slave. As MASTER or Master w/slave No pink LED at any time. Reset as MASTER . USB Connection to PC. 2. An identical second Acomdata box with a second new WD 1600 AAJB drive behaved exactly the same. It was not recognized in the Dell 740. 3. Initially, the Device Manager USB list showed a yellow warning for a USB Mass Storage Device. Uninstall and reinstall hardware made no difference. A subsequent repeat of uninstall/reinstall caused the yellow warning to disappear. When the drive was reinstalled, a small screen popped up in the Notification area telling me that new hardware had been found. 4. My Computer ' Open - eventually showed H:\ ( as well as W X Y Z, the card readers). At that time, Device Mgr. USB Mass Storage had no yellow warning any more. Storage ' Disk Management did not show H: at that point. An internal inconsistency. ----- When I tried to FORMAT from the OPEN drop down menu, H:\ was shown to be inaccessible. 5. Tried the Acomdata drive system on an iMac and two functioning Sony Vaio PCs running Windows 7. None could see the external drive. 6. Tried one of the units which is a 509 Combo case with both USB and 1394 connectors. When connected to the 1394 board in the PC, the boot up hung up at the Windows screen. Restarted in SAFE MODE: booted OK, but the Acomdata drive was not visible in My Computer' Manage' Disk Management. Or just OPEN for a list of devices 7. Microsoft and other sites had all the same ineffective directions for taking care of the Code 10 ' Cannot start this device. (MS blamed it on a 1394 device in one place!!). 8. No one mentioned anything about how the HD should be set up, while Acomdata's instructions were to set it up as a Master, which I did. 9. After spending several hours on this with these two new (WD1600 AAJB) drives and two Acomdata cases no success. 10. Contacted WD support for help via E-mail. They responded that they do not support the drives unless directly connected to the mother board. [ i.e. they did not know or have any idea either]. 11. Searching the Internet, the problem shows up very frequently for many people, regardless or PC make or Windows OS. --- When I first acquired the Acomdata case, it worked OK. I actually installed Windows XP - pro on it with some files. That drive is not recognized either in that case any more. (Different PC ?!) .

SOURCE: win98se i did it ... HERE'S HOW

OK, I bought this Western Digital MyBook 500 GB Essential Edition too, and could not get it to work with Windows 98 SE.

I followed the above instructions, but my version of windows was missing even the drivers suggested above! UGH!

HOWEVER, I found ANOTHER SOLUTION. I installed USB 2.0 drivers for mass storage and the the MY BOOK icon popped up on my Windows 98 SE machine. Hurray! Hurray! Hurray!

Here are the drivers from this british webpage:

Good luck to all you frustrated folks scooping your info off Windows 98 machines!

SOURCE: WD Caviar SE16 WD3200AAKS 320GB 7200 not recognized at install

Windows XP does not have built in SATA drivers. You will need to download the XP drivers from Western Digital's website and install before the computer will allow you to format and use your new drive. Hope this helps.

SOURCE: USB External Hard Drive cannot access. Disk

If the drive is available, with a blue bar in disk management, just right click on it and select 'change drive letter and paths'. This will allow you to assign your own drive letter.

If you have more than one external drive or if you use daemon tools, powerISO, they may be trying to occupy the same drive letter, which would explain your problem...

If you see a black bar, it would seem your partition was corrupted and you would need to try and recover your data, if necessary (recuva recovery software is an option) and then repartition the drive.

Hope this helps!

Acomdata external harddrive is not recognize on vista

I had a similar issue with windows 2008 and windows 7. the drive lost all its info and had to be reinitialized under both of those O.S.'s..
You can try that as long as it doesn't have any data you need.. Once you do that the drive will work and you can start using it. The file system under vista and above is slightly different than xp.

Problems with Hard Drive


Appreciate the direct "Ask Me".

T your concern:
  • initially, pls verify that it is indeed an external storage problem rather than a laptop USB issue by trying other USB devices and determine if they are recognized and working;
  • disassemble the enclosure of the Acomdata external hard drive and remove the actual hard drive;
  • you would need the use of a 2nd PC, a desktop that could accommodate the HD from the Acomdata (IDE or SATA);
  • install the HD from the Acomdata as a Secondary Master or Slave internally to the 2nd PC;
  • boot the 2nd PC and determine if the HD from the Acomdata will be recognized as a local drive;
  • chances are that the partition of the HD from the Acomdata was messed up. This would explain the blinking blue light;
  • download and install a file recovery program. An example is GetDataBack (unfortunately not a freeware but DEMO is available) and do a recovery. It would take some time based on the size of the HD from the Acomdata;
  • temporarily save the recovered data in the 2nd PC. You can burn this likewise into a DVD backup should the 2nd PC be capable of that;
  • after recovery, re-partition and format the HD from the Acomdata while still attached to the 2nd PC;
  • should the re-partition and format be successful, you can transfer back the temporarily saved recovered files;
  • a nice, simple, fast and safe partitioning/formatting software is Partition Magic (unfortunately not a freeware but FREE TRIAL is available).
  • should the re-partition and format be not successful, you can replace only the HD and/or claim warranty.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
