I have one customer's server with WDC WD20EARS drivers in a software RAID. These disks are of advanced format (4Kb sectors, not 512 bytes). They are configured as follows:
Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 268435455 LBA48 user addressable sectors: 3907029168 device size with M = 1024*1024: 1907729 MBytes device size with M = 1000*1000: 2000398 MBytes (2000 GB)
The problem is, that one drive appeared to have bad blocks and I need to replace it. And this model is somehow out of stock here. What HDD can I replace this one with for the software RAID?
OS is CentOS Linux 5.8. RAID is mdadm.
