Promise pegasus r4 hard drive replacement

After the drive failed and up this point, where I replaced it, I made no attempt to execute neither read nor write operatoins on the disk array, even though I was informed that read operations are safe.Р вЂќР вЂћfter installing the replacement disk drive, I ran the Promise Utility application, and the dashboard reported green in every dashboard item listed under 'System Status'. With RAID5 in a 4-disk configuration, one drive can fail without the impact of data loss. Promise Technology confirmed that I would incur no data loss, since the disk array is set up with RAID5 and that the rebuild process would populate the replacement hard drive with the RAID5 parity bit data necessary for data redundancy. Once Installed I went through the process of manually rebuidling the replacement drive. Since I used a hard disk on the compability list, I felt confident that no issue would arise after replacing the failed disk drive. Promise Technology informed me that mixing and matching drives from different manufacturers and with (potentially) different buffer sizes has no impact on the Pegasus R4's ability to function properly. It replaces the original Hitachi HDS721010DLE630, 1 TB, 6 Gb/s transfer rate, 64(?) MB buffer size, 7200 RPM disk drive.

Toshiba DT01ACA100, 1 TB, 6 Gb/s transfer rate, 64 MB buffer size, 7200 RPM Per the Pegasus R4/R6 Compatibilty List available on the Promise Technology site, I purchased the following compatible hard disk: Recently, I had a hard disk failure in my Pegasus R4 (first generation) RAID5-configured disk array.
