遇到过重要数据突然损失的情况或对数据恢复有兴趣的客户,
可能已经接触了有关企业宣传的有90%以上数据恢复率的广告.但这些广告有很多是虚假的.
据至今调查资料结果表明,
在受委托进行数据恢复的各种情况中20%左右损失比较严重,
打开机盖(Cover)后, 数据恢复率只有25%
1. 突然死机的硬盘
2. 产生杂音无法读的硬盘
3. 摔过的硬盘
4. 被火烧过的硬盘
5. 掉入水里的硬盘
根据现有的硬盘质量和数据恢复技术水平,损失数据恢复的可能性在75%左右.
以下内容是有关公司2001年受委托对2457个硬盘进行数据恢复处理的情况.
现根据故障症状, os种类, 制造商以及Model等分类分析如下:
