Toshiba drive label information and meaning

[BytesBack]

Greetings,
I am looking for a hard drive with the following information on the label (keep reading, there's more to it):

MK7559GSXP
HDD2J51 Z SL01 B

I always like to match every number and letter on Toshibas simply because I don't know the significance of the different characters. The trouble is that I can't find any perfect match for this drive. With other manufacturers, the date and firmware and manufacturing site, stuff like that are all clearly marked, so I know what is important. On Toshibas, though, there is no breakdown as to what means what. I was looking to see if anyone knew what the different letter groupings meant so that I could make a better informed decision of what donor to get. For example, should I get a drive with a 'ZL01' instead of 'SL01' or would a drive with an 'A' instead of 'Z' as the first standalone letter be a closer match?

Thanks for any insight you can give.

What are you planning to do with the donor?

Head swap. That usually means matching country and date with other manufacturers.
