Good day, I'm hoping someone can help me in my current dilemma.
I'm currently running a Synology DS1815+ with 8x4TB WD whitelabel (shucked) drives in SHR. I recently acquired a couple of 12TB HGST HC520 drives and wanted to use them to upgrade my storage capacity. The drives were all tested (and passed) using Hard Disk Sentinel's destructive surface test.
However, as I replaced my first 4TB disk, the Synology told me I couldn't use it as it was 4k native block size whilst my existing disks were using 512. I started to do some research and discovered that I could use HUGO/wdckit to change the block size on the 12TB drive. So, I connected the drive to my main PC via a USB-C dongle and performed the following in Hugo: format -b 512 --fastformat -s
The command started to execute and failed (unfortunately I don't have the failure error anymore). Since then the drive is no longer properly recognised by Hugo/wdckit and I can't partition/use the drive (CRC error when trying to partition using windows disk manager). I then connected the drive direct via sata and the drive is seen in BIOS/HD Sentintel, but any attempts to use Hugo/wdckit to run further commands are futile - as no serial is listed I cannot re-run the format command. I've tried specifying the model number using "-m" but the tool claims no model exists. The drive no longer shows a serial number in Hugo and is also listed as SAS rather than SATA. I've installed various WD/HGST tools and they don't recognise the drive.
So, the drive is physically working and reported to HD Sentinel, SMART is fine, but I've screwed up the sector allocation, possibly because I attempted this via a USB-C dongle rather than native.
Am I screwed? What "should" I have done and is there any way to recover this drive?
