Summary: Just what I was promised. I have an old laptop. Its a thinkpad but its still a good laptop. All I needed was a new battery and hard disk. Thinkpads will not accept a HDD unless it's designed specifically for the thinkpad. Since my t60 came out in 2007.
Summary: This hard drive (43N3423) was recommended for the T61 on Lenovo.com. I cloned my old HD using the Apricorn DriveWire kit, then swapped the drives. Re-started the T61 and the new drive roared to life, installing a bit of software for itself.
Summary: I am not familiar with the insides of a modern laptop computer, so this was a "learning experience". This purchase is a replacement for the smaller, slower hard drive that came standard in my 2006 or 7 year old Lenovo T-61 ThinkPad.
Summary: This Toshiba hard drive was purchased in January 28th 2013 for a Thinkpad Edge laptop and worked fine until three weeks ago (March 5, 2014). All of a sudden it would not boot and received an error code 0000.
Summary: I installed it in my ThinkPad T61 and installed Windows 7. It replaced the original 143 GB hard drive that had Windowx XP; I got the "NTLDR missing" message one day and I wasted a lot of time and some money trying to repair.
