Dear Isidoro,

glad it worked for you that way.

Please keep in mind that the Fujitsu MHT2030AT are long time end-of-life
and the disk you purchased was likely used already. Also the -AT Fujitsu
drives are not rated for 24x7 operation thus are a potential problem.
Only the -AS series are classified for "enhanced" 24x7 operation.
Anyway...if i was about to replace a hdd on a routing engine i would
only use a SSD nowadays.

Best regards,
Jonas Frey
