There are many CMR drives that don't work on TE4 on Bolt...
List of drives that don't boot under TE4 21.x on Bolt
Three of which I've tried, are the WD 4TB, WD 2TB (one model), and Toshiba 3TB drives that worked for a few months until TE4 stopped that.
I looked at that thread. If you are talking about the WD 4TB WD40NPZZ that is an SMR drive, not CMR. The 2TB 2.5 WD20SPZX is also SMR.
SSD Micron 5210 Ion 7.68TB SSD, but other sizes probably fail
SSD Micron 1100 2TB SSD, but other sizes probably fail
SMR WD40NPZZ, the only 2.5" 4TB WD rust drive
SMR WD20SPZX another 2.5" 2TB WD rust drive.
Not sure, if same as SPZX would be SMR WD208PZX - reported in another thread. Probably same as as WD20SPZX
Could be CMR but says it might work "Possibly" 3TB Toshiba MQ03ABB300
SMR Seagate 2TB BarraCuda STL2000LM015
SMR Seagate 1TB BarraCuda 2.5" ST1000LM048
SSD Crucial SSD (no model number mentioned)
SSD Samsung MZ-76E2T0B/AM - 2TB 860 EVO SSD
So out of the list in the initial post there is only one CMR drive and they said POSSIBLY does not work, not definitely. I am looking for CMR drives that do not work, not SMR or SSD. The update broke a good number of SMR/SSD. If you can name one specific CMR drive that does not work with TE4 please do, other than possibly that Toshiba MQ03ABB300.
