Omg Toshiba HDD AAAAAAAAAAA!!!
No offence to anyone,but Toshiba HDD are CRAP!
Once I had 6 new Toshiba hard disk drives for laptops and they ALL died withing 20 days!
Also my friend once bought a Toshiba laptop which logically had Toshiba HDD inside and guess what??? In less than a month,the HDD died and was not able to write any data on it.And the data which was BARELY able to be written on it,later when we tryed to save even that little data,OS reported that the data is damaged and next thing we saw was DATA is gone lol and after that HDD died completely withing 24 hours.
Also one of my clients had Toshiba HDD which died after approximately month and a half!
Please don't use Toshiba HDD lol.They are sh!!t !!
Seagate HDDs are the best.I have 2 Seagate HDDs which are about 12 years old and they still work like the day I bought them.I also have 3 more Seagate HDDs which are about 2 years old and they also work perfectly.
So rather buy the Seagate HDD then Toshiba because Toshiba HDDs are crap!True they have good laptops,but HDDs are sh!!t !!

Also never buy WD (western digital) HDDs.They are also shi!!t.Because sooner or later you will hear CLICK-CLICK...CLICK-CLICK...CLICK-CLICK and that means that HDD is dead and your ONLY chance to save the data (if even possible) is to take the HDD to a VERY VERY VERY expensive service.
I had 4 WD HDDs and they all died within 2 months.Also one of my friends who is working in a big company had 2 WD HDDs and they both died within few months and watch this.He was using them VERY rarely lmao!!
So don't EVER...EVER EVER EVER buy Toshiba or Western Digital HDDs!!!
They are cheaper than the Seagate HDDs,but the hell with the price if they work like crap or should I say if they even work.
Seagate is my 100% recommendation to you!
And no wonder why you needed to reinstall Windows 7 so many times in just ONE SINGLE FREAKING WEEK lol.It's because you have crapy Toshiba HDD.Besides...Kill Disk reported you a bad sector on Toshiba HDD lol.
Buy a Seagate HDD and if you take good care of it,it will work for YEARS.
As I mentioned above.I have 2 Seagate HDDs which are 12 years old and they still work perfectly and watch this...NO BAD SECTORS after 12 long years.I am even programming and playing Doom 3 from them lol and it works great!
Also I forgot to mention that I have 3 Maxtor HDDs which are about 11 years old and they ALSO work perfecty just like the day I bought them.
So my recommendation to you is Maxtor or Seagate.I would go with the Seagate if possible.If not go with Maxtor then,but do NOT buy Toshiba or Western digital!
Cheers Seagate!
