[disk analysis failed]

maybe you are, because I just plugged in an external USB drive and DF analysed it fine.

plus if you were not alone, there would be a plethora of other users reporting the problem.

 

you mention 'logical drives', do you mean physical drives?

does the Samsung drive get assigned a drive letter?

what is the file system type?

does it show up in Control Panel -> Administrative Tools -> Computer Management -> Disk management?

 

Thanks for your reply.

 

To expand:  I too have another external USB drive on which defragger works fine.  However on the Samsung 1.5TB drive it simply fails.  By logical drives I mean the partitions on the single drive, each with its own drive letter.  The drive shows up perfectly in Disk Management. 

 

So, the question is: are there some usb drives which fail to work with defragger?

Nobody home?

 

Am I the only one to experience failure of Defrag on an external usb drive?

[disk analysis failed]

Defragger works just great on my installed hard disks.  However when I attempt to use it on one of my external usb drives (1.5TB Samsung) the analysis reports "failed" on each of the logical drives.  Running Win7x64 on Intel CPU.  Latest version of Defragger installed.

  

Can you help.

 

Thanks
