    Hello TSG

    I have a server running '08 64x R2 which has an iSCSI box linked to it. The ISCSI unit has its own management software but has compatibility with Windows products.

    My challenge is that after I reformatted the server 1 logical drive is not accessible. The drive can be seen under the Computer management console on the server but cannot be accessed. I have run the chkdsk command in hopes to resolve any issues but the results come in clean.

    The iSCSI box config is as follows;
    • 5 * 2TB drives in RAID 5
    • 4 Logical Drives in that RAID set
    • SIngle RAID instance support on box

    All drives report a healthy state from the iSCSI unit and as indicated, the results of the repair are as below;

    C:\>chkdsk g: /x /f
    The type of the file system is NTFS.
    Volume label is Full User Backups.

    Hello All

    Just to update you all on this matter....

    The HDD security descriptors were corrupted and each time I ran chkdsk it would tell me that it has cleared them yet it had not.

    I overwrote the existing ones on the drive and applied new ones and hey presto the drive became available.
