Fan Whine

hi all, 2 days ago my sentinel’s fan started emitting this hi pitched whine. called them this morning and support said they will send a replacement enclosure. my question is this, will my data be safe? will it initialize for a long time when i boot the new enclosure up? any feedback would be much appreciated, thanks.

As long as you replace the disks in the same order, the enclosure should read the RAID configuration from the disk set and you should be fine.

As always, you should have a backup of your critical data!
