S.M.A.R.T Status : Not supported

Hi,


I have asked the same question yesterday and received a reply.

But the reply takes me through ERASING my external disk which is not the solution I am looking for.

** Attached the problem and the offered solution below **


I have information on my external USB drive and I do not want to loose that information.

I did not have any problem a month ago and now I do not understand why suddenly the USB external disk looks like unmounted-unpartioned.


I'd appreciate a solution without erasing the info on the disk.


Thank you.

Hi,


Suddenly I cannot read my External USB HD. It gives the message : (Disk you have inserted is not readeble by this computer)

When I check the Disk Utility, the info is as below ;


Disk Description : SanDisk Firebird Media Total Capacity : 67,1 MB (67 108 864 Bytes)

Connection Bus : USB Write Status : Read/Write

Connection Type : External S.M.A.R.T. Status : Not Supported

USB Serial Number : 0123456789ABCDEF Partition Map Scheme : Unformatted


It does not show any other details.


My system info ;

OS X Yosemite Version 10.10.5 (14A389)

MacBook Pro (Retina, 13-inch, Late 2013)

Processor 2,4 GHz Intel Core i5

Memory 8 GB 1600 MHz DDR3

Appreciate a quick support.

Thx.

The disk is not partitioned nor formatted.


Drive Partition and Format


1. Open Disk Utility in the Utilities folder.


2. After Disk Utility loads select the external flash drive (this is the out-dented entry with the mfgr.'s ID and size) from the left side list. Click on thePartition tab in the Disk Utility main window.


3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.


4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the Disk Utility main window.


5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.


6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.


Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

Searching with Google suggests you are not alone with that particular problem with that particular Flash drive. Since you need to recover the files it contains, take a look at this thread in the SanDisk forum; at the bottom is a convoluted set of instructions which may allow file recovery but apparently requires a Windows PC to try out. Note that the instructions suggest YMMV.


BTW, note that SMART status is not normally supported over a USB connection and I doubt the controller in a Flash drive would either.
