Hello to the experts,

Is it possible to flash this HDD with FW version 0104 or 0103 to version 4305 without any problems or is this FW incompatible?
Thank you

Do you have a link to any of the firmware versions? If all the firmware resides in ROM, as in earlier models, then it should be possible to flash any version without problems, I would think. However, if there are code overlays in the SA, then there would be some risk.

Yes, it is possible, i did this one time

Hello,
I have the link here https://files.hddguru.com/download/Firm ... d_4305.exe

I also found this firmware on Lenoveo and also a tj73.ftd, but it couldn't be flashed with OpenSeaChest.
I have a problem with one of my drives where the smart test just stops at 10%.

These are available here too

I examined the .ftd payload files for a few Toshiba updates. They don't look like the ROM images in earlier models, so I don't know whether they are SA overlays or ROM code. I would have to see a ROM dump before I could try to make sense of it, assuming I can. Some of the .ftd files are significantly larger than 1MB, so the ROM would need to be 2MB to accommodate them.
