Yes, I verified the config of the HD and they match. I thought of that, but I don't believe I can clone the HD because it is not bootable. I am running ddrescue (Linux) on it to create an image of the partition. This way I can run a data recovery software on the image and not worry about corrupting the drive. I had backup software running for once a week, Sat night, but would like to see if I can recover the data in between backups.
I called Lenovo Tech Support and they only had the build config's in their system and did not know if it could be upgraded. They forwarded me to Sales, but their system was down. Tech support did however give me a p/n (90003046) but it is a Lenovo p/n. I found a site in the UK the sells the board and they give more numbers: CIHM86, DAOWY1MB8E0, & 31WY1MB00A0, but I get nowhere with them either except a site in Indonesia that say's they have have a 2015 BIOS. dmidecode (Linux) says my BIOS is I8KT15AUS 4/18/13 rev 0.15 and it is a Sharkbay. I did find that Intel did make a Shark Bay MB, but that's all I can find on Intel's website. They require chipsets to go any further.
Update: 10/7 I posted on Intel's site and received a reply. Apparently Sharkbay is a Platform that utilize the Haswell (4th generation Intel Core) processor and a Lynx Point chipset. So anyone could've produced the board. He said if the BIOS is UEFI-compliant, it has support for hard drives that are 3TB or larger in size, but Some of the OEMs implement white lists in their BIOS. That is, their BIOS will only support a specific set of add-ons. Looks like it's a good chance it will take the 2TB drive, but I'm back to Lenovo for the answer.
Update 10/9/16: I checked with Lenovo Tech support again, they still did not know, they could only tell me what the system was configured for. They said the max config for the Bios was 1TB because that was the max config of the model, but were not really sure and call Best Buy they would know for sure. I talked to 2 Geek Squad techs, online chat, and they both said it would handle a 2TB HDD. Therefore I will be installing a 2TB HDD.
D_Know_WD, I'm sorry I guess if I can image a partition I could clone the hard drive, it's just neither would be bootable. Would a cloning software still work with corrupted data? ddrescue will write zero's, or skip them , when it cannot read a block (if I read it correctly) and then continues, but it's been running for 2 weeks now and only half way done. I must have done something wrong.
