RAID Repair Help

SATA and PATA hard drives of any models are our explicit specialty. Since RAID of any type is just a set of few hard drives, we are very deep in RAID data recovery service. But before sending the failed RAID to the lab, please have a look at the drive interface connectors. We do not support SCSI and SAS hard drives at the moment. Otherwise we support all RAID and RAID/NAS storage system with any existing RAID configurations existing nowadays in the world with SATA and PATA (IDE) hard drives in the box.

Few questions about RAID recovery by LaptopData Lab

What RAID configurations supported by LaptopData Lab?

SATA/ATA RAID Level  0, 1, 5, 6, 10, 50 and JBOD

What Operating Systems are supported?

Virtually all known OS, including from Microsoft, Apple, as well as variety of Linux/Unix.

Can you recover an external Network Attached Server (NAS)?

All NAS with arrays of SATA/ATA hard drives are supported by default.

NAS or Network Attached Server

If you are not the owner of a big scale expensive server, most likely it has a regular type of hard drives with SATA or ATA interface and you don't need to worry about it.

We also support SATA/ATA RAID with SCSI host connectivity, including SCSI-to-SATA RAID storages like enterprise storage sources for DAS, NAS, SAN, SCSI, iSCSI, IDE, Fibre-Channel, SATA and RAID Storage servers.

For example, we provide data recovery for R-Stor Rx/RA 200/300/400/and 500 series SCSI-to-SATA RAID storage subsystems from Cepoint. Those RAID comes with up to 16 SATA (Serial ATA ) compatible hard disk drives or 16 PATA (Parallel-ATA) compatible hard disk drives.

Important Note:
Please check! If you are not sure what type of hard drives (SATA or SAS?) are in your RAID, you may either check the connector or contact us and tell the hard drive model on the disk label.

SAS Exception and Limitation

SAS defines a Mini SAS 4x connector shown in Figure 2. Even if you have a SAS RAID, don't jump to the conclusion that you have SAS hard drives. Open the box and check connectors on the drives. The thing is that all onboard SAS controller natively supports the ability to plug either a SAS drive or a SATA drive into the same backplane slot. If there are SATA drives, then you are our customer!

SAS / SATA compatibility is accomplished with a keying area. As seen in Figure 2, the keying area on the SATA drive is opened (gapped) and on the SAS drive it's closed (sealed). The SAS backplane connector is made such that it will accept either a SATA or SAS drive.

About single disk failure protection

Some RAID levels will make your systems immune to data loss from single-disk failures. The problem might turn into disaster because RAID will generally allow you to keep systems up and running with single hard drive failure. And it will keep running until the second failed HDD in array make data inaccessible for user. Then we are here to help repair broken RAID and safe data.
