I have a 4 disk on raid 5.....
One of them fail and I replace it with another compatible HD of the same size and didn´t work...
After going into the Storage Administrator console I found this.
Original drive
Size 279.46 GiB (300.07 GB)
Drive Type SATA HDD
Model ATA WDC WD3000BLFS-6

Hot Spare
Size 279.40 GiB (300.00 GB)
Drive Type SATA HDD
Model ATA WD3000BLFS-23YBU
Serial Number WD-WXE0C79P7715

The 0.06 GB difference is making this drive not to work with the current array?

I would not think it would.  have you run the HP Raid Array configuration Utility to see what it says?
I would think that your cache battery would be the culprit.

0.000001 GB smaller and it won't rebuild since it has to copy *all* the data from one disk to another, not 99.99999% of it. Your easiest solution is to put a 450GB in as replacement for the failed disk since your original is slightly bigger than 300GB.

Any 300GB SAS HP disk will replace any 300GB SAS HP disk as they short-stroke them a little bit to make sure they are all identical sizes whether they used Seagate, Fujitsu, WD, or whoever as supplier but again HP 300GB will be too small for your 300.07 GB one.

The problema was the size of the disk....  the supplier sent me once again the wrong size and before I could buy a bigger one,,,, a power failure crack my last disk and the Raid went to FAIL... :(

I spend all weekend recovering back from my backup, I created a new Raid 5 with the 299.9GB drives, and everything went back to normal!

Thank you,
