CHKDSK Stage 3 Fails - Insufficient disk space to fix the security descriptors data stream.

[Rammiz Omar]

Hi there

I have an external USB drive (Iomega eGo 1TB). It has been kept immaculately (never dropped) but I admit to doing unsafe unplugging when I use it on my laptop (Windows 8.1).

This seems to have result in corruption somehow so I wanted to run a CHKDSK /r f: (or /m) on it which fails with the following error:.

Insufficient disk space to fix the security descriptors data stream.

I have done a number of different things with it (various programs but they all seem to fail.

Any clues on SPECIFICALLY how to pass Stage 3 of CHKDSK so that it can complete the security descriptors stage?

Any help appreciated!

First, I'd copy all the critical data on that drive to another location.

Second, I'd run Seatools for windows on the drive to check it's health. Run the short DST and then the long generic. It may either be able to complete it's testing or give you a more accurate description of why it can't than a standard checkdisk run will.

Third, if no solution can be found, and after backing up the data, I'd fully repartition and format the drive. Or delete the existing partitions, create a new partition and then run the Seatools short DST and long generic tests.
