I'm wondering if anyone has any opinions on the schuckability or anything else with regards to these two external 4TB drives:

WD My Book 4 TB USB 3.0 Hard Drive with Backup

WD Elements 4TB USB 3.0 3.5" External Hard Drive WDBWLG0040HBK-NESN Black
http://www.newegg.com/Product/Produc...2236807&cm_sp=

I have a late-2013 version of the WD My Book that I shucked for a Hitachi 4TB. It works fine, but it's a bit slower than my recent Seagate Expansion 4TB drive (also external and shucked).

there was a deal i bought yesterday from NE for a samsung d3 5tb station drive, which has st5000dm000, but now I am having second thoughts.

after reading up on this drive, i realized smr is not the way to go, if you need to rewrite on this drive. Basically this 5TB drive is a 4TB drive with smr heads, i thought they increased areal density to get 1.25TB per platter, but now after reading up on smr they are just overlapping the writes on these drives to get 5TB in four platters.

Also, I dont think you can compare similar firmware names for different model drives, cc44 on this drive is not going to be the same as cc44 on a sata ii drive. Because SMR has a completely different writing technique that was not around when they had cc44 firmware on the sata ii drives.

Its like saying a samsung ssd firmware version 1.01 is the same from model 850 pro to 830

I actually wrote that review (Timmmay) and there are threads here on AT about it. I got in legal trouble with Seagate and they sent me a cease and desist citing the digital millennium copyright act when I started detailing on various forums ways to bypass/modify the firmware AHCI restrictions that prevent "shucking" into a PC.

So yes, all 1GB/platter external drives, as far as I know, are un-shuckable.

You can thank BackBlaze for having a HUGE role in turning the hard drive industry upside-down on external storage design. During the hard disk crisis of 2011 (Thailand) they broke all sorts of laws and store policies on purchasing, bulk buying, and so on (we're talking thousands of drives they bought at bottom dollar, wiping out inventories nationwide during a consumer supply crisis) that the hard disk industry responded two ways: Seagate modified their firmware to only receive IDE commands and "detect' when it isn't attached to the exact USB-SATA bridge chip they use on their external enclosures, and WD, who went a step further and actually uses a DIFFERENT PCB on their external drives.

Anyway, long story short, the 5TB drives are a great price for the space, and the enclosure is ok, but the PSU makes a buzzing noise when the drive is in standby (it stops spinning after idle for a few minutes) and obviously you can't "shuck" them.

I did not care about HDD problems like head parking (except bad sectors) until my 1,5TB WD Green HDD was dead after 5 years, which was used as my OS drive ! it is not dead completely but the SMART fails in testing, copying is very slow and it freezes in reading about 15-20s sometimes.
I have three Seagate ST2000DM001 (two from backup plus, one from goflex home). Two of them are 1CH164 (from backup plus boxes) with firmwares CC43 and CC82. The CC43 one (I took it out the box and used it as my OS internal drive now) is updated to firmware CC29 (not CC49) while I cannot update the firmware for the CC82 one (still use it as backup plus box). The other drive 9YN164 (used in goflex home NAS) has CC9F firmware and I am unable to update the firmware too. The APM values of all three drives are 80h (128). LCC of two 1CH164 drives is about 3.7 cycle/h. However, 9YN164 drive reaches 33k of LCC.
Do you know what are the differences between CC43, CC29, CC49, CC82 and CC9F. Is there any way to update CC82 (also 1CH164 drive) to CC29 or CC49 ? There is CC4H for 9YN164 drive, but CC9F seem to be different in hardware, how can reduce the LCC of my 9YN164 drive in my goflex home NAS ?
Thank you for the help.

I finally got around to shucking three of my 5TB Seagate externals and here's what I found. They are all ST5000DM000 units. Each had a different firmware (CC46/CC47/CC48) as I purchased them a few months apart.

They all had APM enabled and it was set to "80h". Did some Googling and came across a SPCR post on how to disable.

http://www.silentpcreview.com/forums/viewtopic.php?f=7&t=68760

Following those steps, I was able to disable APM on all three units even after a power cycle. Verified as disabled using CrystalDiskInfo.

Nice, thanks for the heads up. I have an bunch of ST4000DM000 and they all racked up 300K head parking events before my monitoring tools alerted me and started disabling those in software (I think it worked?). They still work even with 300K parks, but it would be nice to disable the stinking feature forever.

Does anyone here still own a Seagate 5tb Hard drive with the firmware CC43? I had one but the pcb fried and it has some really precious data on there. If anyone has one and would be willing to sell it to be I'd pay full price of a new one AND send you a replacement! Please help me!!!:'(
