I have Windows 7 HP 64bit SP1 system. I've had and used my SSD for about 3 months and was very happy with it. But suddenly one day I could not install any program or windows update. I could not install any update from a program that I've had and could not install any programs I just downloaded. I have run a CMD chkdsk and all my windows files are genuine. I ended up having to switch over to my old hard drive and everything works fine on that hard drive. I have tried many solutions that I have found online and none seem to work, or they require me to download and install something for it, and obviously I can't do that. I do remember doing a disk cleanup on that SSD because I was running out of space. (before the issues started) If I have to download some tool, I would need it to work if I download and install on the hard drive that works, and fix the problems with the SSD. I have tried to contact Samsung but they told me in order to fix it they would have to wipe the drive. I do not want to do that. Any tips could help. Thank you.
