Disk Director 12 cant see ext drives

Thread needs solution

Win 7/64 bit

I have 4 USB 3.0 external drives:

2 - Seagate Backup Plus 4 TB
1 - WD My Book 3TB
1 - WD My Book 2 TB

Out of these 4 drives Disk Director 12 only sees the 2 TB WD.
All of them show up in My Computer.

Any help is greatly appreciated.

Hello there,
I have a 3 TB USB 3 hard drive from Transcend.
It will be displayed in Windows 7 64 bit, but not in Acronis Disk Director 12
What can I do??
Best regards
Alexander

I have 3 & 4 TB Seagate Backup Plus USB 3.0 drives that also cannot be seen by DD 12. I have 3TB Seagate Drives in StarTech USB 3.0 enclosures that can be seen by DD12.

Same problem all of my USB hard drives that are GPT and have 4k sectors do not show up in Disk Director 12 build 12.0.3223
My 4tb raid 1 GPT with 512 sectors shows up just fine.

Thank You

Hello,

This is a known issue.
For now, Disk Director 12 is unable to recognize disks with logical sector size not equal to 512 bytes.

Our development team is working on it.

Best regards.

Seit 09.2015 oder noch früher ist ihnen bekannt , daß ihr Disk Director 12 keine 4kb Sektoren HD öffnen/bearbeiten kann. Trotzdem werben Sie immernoch mit der Fähigkeit 4kb HD bearbeiten zu können. Stand 01.April.2016 FehlerCode: 1.048.576(0x100000) "Kann 'Laufwerk 4' nicht verarbeiten, weil dessen Sektorgröße (4096 Bytes) nicht unterstützt wird." Ich hatte auf DD12 Upgedatet , weil ich der Meinung war daß das Produkt diese Fähigkeit hat. Da die HD's ja immer größer werden ist dieses Produkt dann wohl nutzlos.

 

I'm in the same boat. 
- Windows Computer management/Disk Management can see my external USB drives
- Acronis disk director cannot

I used default settings when formatting the drives.  I would like this product to work with default Windows settings. 

I went to format my drives, and 512k isn't even an option.  (See attached image)

Hello, Wayne.

The value you choose when you format a partition in Windows (what we see in your screenshot) is "cluster size" or "block size", not sector size. The logical sector size is a property of the physical drive itself (or can depend on the storage adapter). So no matter which allocation unit size (cluster size) you choose when formatting the volume, your logical sector size stays the same. Please see this Knowledge Base article for more information.

Dmitry, thanks for the information.  It appears there's nothing I can to to affect the logical sector size.

Per the knowledge base article, there is a path to try.  In an absolute emergency where I need to try a recovery, I'll try pulling the drive out of the USB case and plugging it in directly.

Unfortunately that won't work either.  If you remove the disk from the enclosure the sector size will change and the partition structures on the disk will be unreadable.

Joey,

Can you explain that more?  I've moved single drives from internal SATA drives connect them to USB drive readers (either a case or a tool) before without a problem.  I've likewise taken USB drives full of information and mounted them in my system, connecting via SATA.  I've never had an issue reading them.

I am missing a piece of information, and would appreciate if you could educate me.

The controller of your USB 3.0 drive enclosure is translating the logical sector size of the internal disk from 512 to 4096.  This allows the disk to be formatted MBR with capacities larger than 2TB for compatibilty with Windows XP.  The problem this creates is that the partitions and data are only accessible through the contoller of the enclosure.  When you connect the disk directly to your system with an intenal SATA connection it will be using a logical sector size of 512.  Since the data on the disk is aligned for 4096 sectors, the disk will be unpartitioned or RAW in disk management.
