Lenovol z50-75 factory reset (external hard drive write protection, slow transfer speed to usb)

Hi,

 

After weeks of trying to get an answer to this problem without any assistance, either online or here (what's the use of a warranty when there's no customer service to speak of?) I tried transferring some files to my flash drive a day ago.

 

The thing that happened now was that the transfer started out fine for the first few seconds (as usual), before crawling to a halt and then stopping completely - I can't remember what the exact message was, but it was something in the vein of "problems with disk". I then found out that I could neither add or delete files to the flash drive as it had been write protected. I searched online for how I could remove this protection (regedit, command prompt), but nothing helped - to my great, great frustration. Therefore, the flash drive is now useless to me, thanks to the laptop.

 

I then experienced that the external hard drive that I tried to transfer the files from had also been write protected! Before pulling out my hair I checked if this was also the case when I plugged it in to another laptop (Asus). It wasn't. But on my Lenovo z50-75 that hard drive is useless for some strange reason.

 

After experiencing this mountain of problems I want to do a full factory reset on my laptop, and then reinstall all my programs. My question is how I go about doing this. And also: when doing the reset, will it boot up with Windows 10, as it did when I purchased the laptop a little over a year ago?

Hi  goatfog, 

It seems like your z50-75 has a malware. You may want to run a complete scan using an good antivirus before doing a reset. You can also run sfc to check if the system has any integrity issues.

Now for your question about the factory reset/Onekey recovery, if you are going to use windows 10 reset, then your system will still have window 10 but if you use Onekey Recovery, the system will go back to the original OS that came with the system.

According to windows 10 FAQ, you can then re-install windows 10 even after doing a reformat.

Hope this helps. 

Cheers,
