WD Spyglass 4TB - HSA Donor Match

[samstown]

Hello,

In the past, I've been always lucky with Spyglass HSA swap. I got a new case and instead of waiting for luck, I would like to find out what is important/critical for the donor to match. I find WD much easy to match than Seagate.

My donor have same pre-amp than patient, is this always enough ? Thanks to fzabkar for the ROM parsing tool.

Thanks
Sam

thank you for your post. Yes, I've seen this and it's always helpfull. For you what is the order from easy to difficult brand to find good donor ?
WD seems to be more flexible than Seagate.

I would say

WD (easiest)
Toshiba
Hitachi
Seagate

Toshiba is definitely the easiest.
Matching the model is good enough most times.

I don't do the volume of swaps larger labs do so it's difficult to say really, but it's certainly easier to find donors for most wd and seagate than it is for hitach, very rarely get toshiba drives in.

Matching HSA (third character past bracket) works for me.

I did the swap and it's working without problem, i am cloning. Those WD are not the worse. I have more problem with charger familiy
