Hi,
I'm pretty new to this forum and have not that much of experience with recovering data from hard drives yet. I'm not a native english speaker so please forgive my english.
I have the almost same drive:

Drive: ST500DM002-1BD142-500
Firmware: KC45

with this error in Terminal:

Boot 0x10M
Spin Up[0x00000000][0x0000B67C][0x0000BA10]
Trans.

Rst 0x10M

I read a lot in this forum and already tried quite a few tweaks like disabling media cache and other congen stuff with no effect so far.
I portet the tool "stuart-0.9" to read at least some of the data, but got stuck at some point.
I found out, that all blocks I tried to read beyond LBA 150b9a have read errors The blocks below (around the first 4GB of the drive) where OK.
I raised the ECC-Level to maximum and set read on error flag on and realized, that erroneous blocks could be read at least partially, for example I tried to read the MFT$ file of an NTFS partition and the first kB looked OK, the rest of the 4kB block was garbage, but it was everytime the same garbage (at least the checksum where always the same and it was not a remainder of a previous read of a good block or something like that)
This lead me to the assumption that reading the data gets out of sync, somehow. But I have no idea how to solve this.
I hope someone can help me with this issue!
