I had a few laptops that were taking a long time to start Windows. I scanned them with HDD Regenerator and they showed as having delays at the beginning of the drive. I tried repairing them with the program but they still showed the delays. They were still slow after doing a format and a clean install of Windows 7. They were 120-160 GB drives so I just replaced them with new larger drives. I installed Windows and they started up with no problems. I then had someone ask me if I had any 2.5 drives that he could use to upgrade his PS3 12gb hard drive with. I again tested the drives in a laptop and they still showed the delays. I then found out that PS3 drives need to be formatted as FAT32. I attached them externally to my desktop and formatted the entire drives as FAT32. I again put them in a laptop and ran a scan with HDD Regenerator and the delays were no longer there. I reformatted them as NTFS and put them in the laptop and scanned them again. The delays no longer show. I installed Windows 7 and they now start up normally. Could the reformatting to FAT32 and then to NTFS again have repaired them?
