hard drive replacement

[1siamesekitty]

I need to replace my sick hard drive. I know that I need a 7200 rpm Sata 3 . I would like  a 2TB, but how do you nchoose the brand? how do I know that the size is right? My computer is a 4 core, does that make any difference?

1. If it has some "residual" life, it's possible that a "disk-cloning" procedure can be used to copy, block-by-block, from "old" to "new".  If a few blocks cannot be copied, then 99.9999 % of the blocks have been copied.  If you are "lucky", the contents of those "uncopyable" blocks are not essential, e.g,. keyboard layout for Finnish keyboard.  Then, boot from the new disk-drive -- all your programs and personal files will be present.

2. Yes, it spins 33 % faster than a 5400 RPM disk-drive. 

SATA 3 transmits up to 6 Gb per second, while SATA 2 only transmits up to 3 Gb per second.

3. There are only a few remaining manufacturers, e.g., Seagate & Western Digital.  Maxtor is now part of Seagate.

If you purchase from either of these two, there is free "disk-cloning" software on their web-sites.

4. It's getting impossible to purchase any brand-new disk-drive less than 1 TB.  Some older motherboards have a built-in maximum of 2 TB.  How "full" is your current disk-drive?

5. No.
