You can access the My Cloud Dashboard to find the firmware version.
If the single bay My Cloud is running firmware 3.x or 4.x it is a first generation My Cloud unit.
If the single bay My Cloud is running firmware 2.x it is a second generation My Cloud unit.
Or one can look at the P/N number on the bottom of the single bay My Cloud unit enclosure or the product box/packaging.
If the P/N ends with “-00” it is a first generation My Cloud.
If the P/N ends with “-10” it is a second generation My Cloud.
One can use the forum search feature, magnifying glass icon upper right, to search through this subforum to find several past discussions on the model numbers and hardware differences between the two single bay My Cloud model versions.
If the seller hasn’t posted pictures of, or listed, the full P/N number of the unit up for bidding you will have to contact them and ask for the full P/N number or have them access the Dashboard to get the firmware version number.
I had looked at your link before, but couldn’t quite parse it out. Now that I have a need, I understand! ; -)
So for future searchers (and my notes)
WD MyClould Single Bay
1 … WD BCTL 0040HWT-NESN
2 … WD GLCR 0040HWT-NESN
Of course other parts of the model number are defined in Fox_Exe’s link, the 2 remaining segments, 0040 define the number of terabytes, and NESN is a region? code. The other regions may be posted in WD documentation, but sorry, life is too short. ; -)
Many of you say that this is a gen2 model because it ends with 10. But nnnn_mm wrote that wdBCTL0040hwt-nesn belongs to gen1 and models with wdGLCR0040hwt-nesn are gen2. I can not check my mycloud at the moment cause i have the flashing blue light issue.
If your P/N number on a single bay My Cloud ends in “-10”, you have a second gen v2.x single bay My Cloud. The first gen ends in “-00”. If one looks at the WD Support page for the single bay My Cloud (https://support-en.wd.com/app/products/product-detail/p/126) they will see even WD flat out states the P/N numbers for each version that confirms this:
.00 1st generation 6GB I just bought a year ago and now becoming obsolete. Ridiculous corporate greed. Don’t talk to me about going green when I have to constantly throw printers and backup drives away. Greed and rude when you are still sell old junk on Amazon and now obsolete. Global ecology and going green my jackass
Huh? Not sure what your rant has to do with the issue (single bay My Cloud model numbers) of this discussion. We are users like yourself and have no control over what WD does other than not to buy their products. Throwing old drives away? Why not just shuck the drive from it’s enclosure and use it in a computer (either on a spare SATA port or using a USB to SATA adapter/docking station) rather than throwing it away. Or shuck the drive and use it in an NAS enclosure from another manufacturer. There are ways to recycle and properly dispose of old electronic/computer equipment in most countries/locations.
