Minimize the Risk of Lost Data When Your Computer Won’t Start.
There are a myriad of reasons why a computer won’t start. One is a bad sector. Sectors going bad on a hard drive is a common occurrence. Modern hard drives are designed to recognize the failing sectors, copy the data to another sector and stop using the old one. Sometimes a sector goes bad before the hard drive can adapt, causing the loss of a file required for start-up. When this happens you may get the “Non-system disk or disk error” message, or windows may ask you if you want to launch start-up repair. Using windows start-up repair, in this situation, can cause more damage, sometimes irreparable damage, to your hard drive. To minimize the risk of data loss, if you have vital data on your hard drive, and if your drive is making a clicking, grinding, buzzing or beeping noise, do not use start-up repair, or any other disk repair utility. In fact, it is best that you do not power on your computer at all, in this situation. We have had many customers with badly damaged hard drives, who later tell us they wish they had known that even powering on a failing hard drive can cause permanent data loss. If your data is not that important to you, and you can accept losing that data, then processes like start-up repair may be the right choice for you, but if you can’t afford to lose your data, have your drive evaluated by a professional data recovery company that offers free evaluations, and a no data no charge policy.
