WRR-5301/5501 - Reporting Incorrect Drive Size in Windows


WRR-5501 Reporting Incorrect Drive Size in Windows


Applicable products: WRR-5501 servers

The objective of this document is to guide identifying the issue and provide instructions to correct the issue in which Windows OS is incorrectly recognizing the correct volume size of the RAID configured storage and to assist in the retention of existing video storage currently saved to said volume in WRR- 5501 server product.




To identify the issue:


For example, WRR-5501-24TB should have D:\ size of approximately 16TB.Please check the size of the D:\ and compare with the configuration ordered. Be sure to properly calculate the storage size with RAID-6 in mind. To calculate usable space for RAID-6, refer to the table to the right.

If the D:\ storage size matches the table, the server is not affected by the issue.

If the D:\ has significantly less capacity, please continue.
