It's in these cases that the robustness of a Solid State Portable Drive is paramount. A drive cannot fail and data cannot afford to be lost. Your drive must not be only rugged but also secure and this is where the iStorage diskAshur Solid State Drive is unparalleled.
Information Commissioner's Office (ICO)
The Information Commissioner’s Office (ICO) now has the power to fine businesses and government bodies up to £500,000 for serious breaches of the Data Protection Act. This includes the loss of an unencrypted USB flash drive that contains client data. The ICO has been very clear in advising businesses and government bodies to encrypt all data that workers access, they also recognise that data which is encrypted and lost or stolen is not vulnerable to compromise.
General Data Protection Regulation (GDPR)
The European Union will soon have the power to fine companies €20 million or 4% of their annual turnover if they are found to be in breach of the new General Data Protection Regulation (GDPR). The forthcoming legislation compels anyone who holds data on EU Citizens to implement adequate security measures to protect data from loss or theft.
Loss of confidential data can have a devastating effect on both businesses and consumers. It could lead to a hefty fine, the downfall of a business, embarrassment, job losses and adverse media attention. The iStorage diskAshur SSD can protect you against all of this.

iStorage diskAshur Introduction
We strongly recommend that you carefully read the User Manual, shipped with the device and/or available for download on our website before contacting us for technical support.
There are no ‘Back Doors’ to our products, we cannot retrieve a forgotten PIN or retrieve any data off the drives unless the PIN is known.
Below are answers for the most frequently asked questions:
You can use it in one of the following ways:(1) Change the Admin PIN or create a User PIN;

  • Connect the iStorage diskAshur SSD to your computer’s USB port, you will get a solid RED light.
  • Hold down the 0 & Padlock keys for 5 seconds, RED light flashes.
  • Enter the Admin Mode with 123456 & Padlock (default administrator password), the BLUE light then appears signalling the iStorage diskAshur SSD is in Admin mode.
  • You are now able to change the Admin Password or create a User Password in Admin mode.


(2) Directly enter the User Mode to start using the iStorage diskAshur SSD;

  • Connect the iStorage diskAshur SSD to your computer’s USB port, you will get a solid RED light.
  • Enter the Admin code 123456 & Padlock (default administrator password), now GREEN light appears and iStorage diskAshur SSD is ready to use.
Any new Admin or User code that is setup has to be a minimum of 6 digits and be no more than 16 digits long (6-16 digits).
Use your Admin PIN to enter Admin Mode, and then create another User PIN in Admin Mode.
There is no other way to retrieve the Admin PIN except a complete reset of the iStorage diskAshur SSD. After a complete reset, all data will be lost and you will need to initialise, allocate and format the iStorage diskAshur SSD manually. You then will be able to use the default Admin Password 123456.
You need to initialise, allocate and format the diskAshur SSD manually. For more information, refer to “Initialising and formatting the Hard Drive after a complete reset” in the product manual.
No, this is a Windows limitation, you must use the Admin account to initialise and format the iStorage diskAshur SSD.
As a full disk encryption product, the iStorage diskAshur SSD can never be used without a password.
The iStorage diskAshur SSD uses AES 256-bit algorithm.
You can change it only in the Admin Mode. In the User Mode, the User PIN which has the same digits is created in the Admin Mode cannot be changed or deleted.
Ensure that you have administrator privileges for your computer. You can use only the administrator account to initialise partition or format the iStorage diskAshur SSD in the User Mode.
The Administrator feature allows enrolment of up to FOUR (4) unique User ID’s and ONE (1) Administrator. If a User forgets their PIN, the diskAshur SSD can be unlocked using the Admin PIN.
No, since the iStorage diskAshur SSD does not require any software to be installed and the encryption/decryption is performed in Hardware on the drive itself, “Admin Rights” are not required.
You may have entered an incorrect PIN too many times and have triggered the Brute Force Attack Protection; you can reset this counter by referring to the `Brute Force Attack Protection` section of the iStorage diskAshur SSD manual.
The issue you are having is being caused by power saving settings on your computer so please see below and make the appropriate changes to your computer and this will stop the iStorage diskAshur SSD from locking.

Microsoft Windows

Doing the following will prevent Windows from switching off the diskAshur SSD, go to `Control Panel` & `Power Options` , the easier option is to disable power saving which means stopping the computer from `Sleeping` see below;
In addition go into Advanced Settings in Power Option to disable the following:

  • Ensure the computer is set to sleep: Never (as above)
  • Turn off hard disk after: 999999 Minutes
  • USB selective suspend setting: Disabled

This will keep any iStorage SSD connected to the computer continuously on.

Note: For Windows 8.1 users You will need to install a Windows update (KB2919355) as well as follow the steps above. Please go to this link and choose Method 2: http://support.microsoft.com/kb/2919355.
Once the download option appears select KB2919355 and then download and install.

For more detailed information and required fix please go to our support page, under the tab Firmware Updates and download Win8.1 USB suspend issue folder.

Apple Mac

Drives keep locking after 5-10 minutes on the Macs.
This will be due the Mac’s power saving as there is a setting to switch off hard drives that are idle after a fix period of time see below.

The settings in Energy Saver preferences affect what happens when your Mac is left unattended for a period of time that you specify.

Disable Put the hard disk(s) to sleep when possible to prevent the diskAshur SSD going to sleep and not locking. You will also need to stop the computer sleeping to prevent the diskAshur SSD from locking.

The only way to prevent this is by changing the power settings (Windows computers) of the computer so that it only switches of the monitor on hibernation/sleep and keeps power to hard drives and USB. On Apple MAC computers going to the power settings in `System Preferences` and clicking the do not suspend USB will keep the drive alive even if the MAC goes into full hibernation
Your computer may not have enough power going through to the USB to power the iStorage diskAshur SSD. Use a USB Y-Power cable to ensure full power to the iStorage diskAshur SSD.
To make the iStorage diskAshur Solid State Drives universally compatible with all the most common Operating Systems requires the drive to be formatted using the FAT file system. This is done by using `Disk Management` in Windows, `Disk Utility` on MAC OS/x or MKFS in Linux. in Windows and Disk Utility on MAC OS/x or MKFS in Linux.
BadUSB is a theoretical exploit that was presented by SR Labs at the Black Hat conference in August of 2014. SR Labs demonstrated a vulnerability in one USB device that allowed malicious code to be programmed into the USB controller through a firmware update process.
The attack described is very sophisticated and in the case of iStorage products would require advanced knowledge of our USB controller, a leaked version of our firmware, the programming tool to update our controller, the password used for our programming tool, and an in depth understanding of the device’s functionality, etc.
According to SR Labs, the failsafe method to eliminate this threat is to simply disable the ability to update the controller’s firmware. Many of iStorage devices shipping today, including all of our USB 3.0 security products already have the firmware locked which prevents field updates to the USB controller.
As a continuous improvement, iStorage is locking down the firmware on all USB controllers used in iStorage devices to safeguard against this vulnerability. We recommend checking our website periodically for notices regarding BadUSB and Security Updates.
Your PC has a small bug that is called the USB Selective Suspend.  This error first occurred with Windows 8 and rolled over with Windows 10 and server 2012 R2.  This bug stops the windows update service from fully installing the Vendor ID and Product ID for the iStorage product into the windows registry.  This is vital information for the registry to have and stops the devices from disconnecting after a set amount of time.

We have contacted Microsoft about this matter and they have provided a fix for this issue.  It can be downloaded directly from this link HERE.
