Be careful when you add an extra disk to your system just to get more space
Hard disks are delicate stuff, so when you add one mor to get more space, you should add even on more after this to backup this extra space, now and forever.
A hardisk aging 3 years or more should be considered "old" and may have faults to it, If you archive soething on one drive and nowhere else, you should
think of it like any day you could loose all the content on it.
so reuse of older disk just because it is cheaper than buying a new could be a costly experience if you now loose data from two disk.
Basically what I'm saying is this, yes you can make an external disk from an internal disk, although those are not designed to be treated as external disks, you should only us the second disk as an extra copy, not to extend the space, that way you have "free" backup drive.
Now, I'm not sure how you made this external disk. Did you buy a USB to SATA box or somthing, or did you basically just plug in the extra disk inside your
cabinet on a free SATA-connection?
Also I cannot see why you want to format the disk, instead of deleting data, if you want to format the disk to make it "impossible" to retrieve old data, that is not the best way.
If you simply need more space and need to remove data it is much safer to review the disk and erase folder by folders and files by files, so you see what you erase.
There are lots of good tools out there letting you see disk contents, unerase contents, show partitions etc.
Just be careful when you use such programs if you are not familiar with them, so you do not remove data you want to keep.
And as stated above run speccy to let you have an idea what parts you have on your computer, and try to explain what you want to do, why you want to do this,
and what outcome you expect. Removing all data on a disk takes only a few seconds, but retrieving lost data could take a long long time, so be careful what you do.
For the record, I received a 4 TB external desktop office disk a year ago, I backed up all I had, I did not erase the source, but I did reorganise the data on the external disk.
I brought this 4TB to another place to backup that computer too, and the disk was ticking (broken)
I lost all data on the 4TB ( I got a new from the retailer but who care, I lost the data... or actually I lost many hours time spent making the backups, since after all I used the drive for backup, not to extend the space) This was a 14 day old 4TB that time, so I learned the lesson, never transport a disk like this from A - B unless you have a second backup. Now I use smaller travelstore disk or SSD-disk instead, but most important, I stor things on multipple places, even before considering erasing data on my computer.
So think twice no matter what you decide to do
Speccy is from piriform and they also have these sometimes invaluable porgrams, one to erase all kind of stuff anonther to recover
data you have wrongli erased: ccleaner recuva and speccy
You ow yourself a chance to experiment with the programs, and now that you have 250 GB disk you wanat to do stuff with thats a good place to experiment, you might get stunned what you find on that disk with recuva (recovery sw), and since you apparently do not need the data from the drive
ccleaner could help you. Just be careful you do not erase the wrong disks
