Purchased refurbished Acer aspire A315-58. I tried to reinstall windows as it came with home edition. I had a lot of trouble doing so but finally managed to do it after changing intel storage settings in bios - they are normally hidden u have to press ctrl + fn + S to show it. After installing windows, laptop runs fine once it boots up but now issue is booting up takes 1+ min on m.2 ssd. CHKDSK shows there are errors and can't repair because Drive is write protected, on boot, CHKDSK starts and stops and I think reason for long boot is this checking, I can only see swirling loading, then it displays press any key to cancel repair >10 sec countdown > into 3 sec failed scan & repair sequence and then boots into windows. SSD shows 100% health in crystaldiskinfo and has latest firmware on it. The SSD is Toshiba THNSN5512GPU7 512.1 GB. If I try to enable intel storage settings in bios and boot up, boot fails displaying couldn't find bootable device. I don't know what to do, I thought SSD issue was over after managing to reinstall windows but it's read-only status seems to be untouchable. I tried to remove write protection using disk part but no success. I have owned so many computers and none of them gave me this much trouble
