The reason and suggestion of data loss in RAID disk array

Server RAID disk array information loss is a nightmare for many webmasters or server administrators, if you have ever experienced a similar RAID disk data loss and then look around for data recovery company things, then you must be fresh in memory of RAID disk data recovery, if you've never experienced it, just heard about it, Then you must look down, the reasons for the loss of RAID disk array information, only to know these reasons to reduce and avoid the loss of RAID disk array information. Days Shield engineers recently received a similar RAID disk array of lost customers, which we based on the day Shield data Recovery Center engineer years of experience, the following situations often lead to the loss of RAID disk array information:

1, the RAID array card fails;

2, disk physical failure, such as bad, disk error, disk response time is too long, RAID 5 damage more than 2 disks.

3, array cabinet or server suddenly power off, and no UPS protection.

4, after the hard drive sequence is wrong, start the system, or blindly change the array configuration information;

5. Reconfigure RAID disk array information, etc.

6, the power is not stable, resulting in the loss of RAID information.

If you notice a RAID disk array failure. Please take the following action.

1, the system power off, the hard drive sequential numbering,

2, report the situation to the disk array manufacturer, or professional disk array data recovery company;

3, do not do their own hands, try to Rebuild, synchronization and other blind data recovery attempt to operate

Days Shield Data Recovery Center engineers strongly recommend:

1: Because server storage is generally important data. After any failure, please be careful to avoid the data caused two damage, serious situation made data permanent unrecoverable

2: After the failure, please power off immediately, contact the server after-sales center or Professional Server data Recovery Center detection, to ensure data security

3: When the array information is lost, remember not to perform rebuild reorganization operations (except if you do not need to recover data), otherwise the data may not be recoverable
