Question: Does this hard drive come with pre-installed operating software, and if so, what?
Document: I returned the hard drive a few weeks ago becasue that drive does not work in my computer. However, I have not recevied any reply from that vendor.
This a very quiet hard disk drive. Haven't had any BSOD or disk errors on this drive. I routinely run Disk Defragmenter and it's been very reliable thus far.
Had to to replace a Dell laptop hard drive. This did the trick. Was able to clone the old drive right to this drive and popped in the laptop and it worked! Love it when a plan comes together.
It seems to be doing what it's supposed to. Having had the lovely experience of replacing my hard drive myself via telephone tech support, I was familiar with the process for this item. It was as described by seller, arrived quickly, and has been working fine for several weeks now. Would buy it again if needed.
Bought this hard drive as a replacement for my burned out Toshiba Laptop. This turned out to be a great buy, because my computer did not have to run in compatibility mode for this HDD. Took less than 5 minutes to swap the drives, and the old mounting hardware fit right in. Now my computer is back up and running :3))
I was a little worried about installing a new hard drive in my notebook computer because I had never done it before, so I selected this drive that was exactly like the one that had died after several years of constant use. The price was better than available elsewhere on the internet and better than all local vendors that I checked. To my delight, the package arrived sooner than expected, which gave me the whole Thanksgiving weekend to play with it.
This hard drive works well and seems to be nearly as fast as the 7,200 RPM hard drive that it is replacing. I bought this hard drive to increase the size of my storage (replaced a 160GB hard drive). The Toshiba MK3276GSX 2.5" 320GB 5,400 RPM hard drive is not one of the newer advanced format hard drives so it should work well with older computers that have a SATA interface. 320GB of storage on a single platter hard drive is a plus.
It works. We had to do some handstands to reformat it for WinXP, since it came pre-formatted for Win8 or better. It's fine.LS
My grandson's hardrive crashed and I could not access the hardrive and recover any information. This was the first time I had ever tried making any hardware changes to a laptop. I was able to replace the old laptop hardrive and reload software with no problem. This was a great hardrive for the price.
in less than 20 minutes. If you need a drive, just go for it!
Answer: Mine did not.  It was totally bare but the computer recognized it upon installation and I had no trouble installing Windows 7.
