RAID & server data recovery
san jose & bay area experts
any system, any failure
Corrupted volumes, failed arrays, unreachable data — we recover what others can’t.
Whether it’s a RAID server, NAS, SAN, or enterprise system, Kotar Data Recovery provides expert solutions trusted across the Bay Area.
why your server’s data may still be recoverable
Servers and RAID systems are built for resilience, but even enterprise infrastructure can fail. From controller errors to multiple drive crashes or misconfigured rebuilds, our San Jose lab has the tools and expertise to reconstruct your data fast.

common raid & server issues we solve
RAID failure – degraded or partially rebuilt arrays
Multiple drive failures – simultaneous HDD/SSD loss
Hardware issues – controller, PSU, or backplane failure
File-system corruption – inaccessible shares or mount errors
Firmware corruption – RAID cards or storage nodes
Failed migrations/upgrades – partial data loss
Accidental deletions – user or software errors
Reconfigured arrays – mistaken initialization or parity overwrite
Malware & ransomware – corrupted or encrypted data
Network or power issues – logical corruption or boot failures
signs of a failing server or raid array
Volumes or shares not accessible
Frequent crashes or freezes
Sluggish performance / high latency
Mount errors or missing drives in OS
RAID controller showing degraded/failed status
Drive LEDs blinking amber or red
Unexpected reboots or shutdowns
Users reporting missing or corrupted data
Overheating or unusual noises from drives
what should you do
Stop using the server immediately (especially if degraded)
Do not attempt a RAID rebuild without a backup
Avoid running fsck, chkdsk, or reconfiguring drives
Document RAID level, drive order, and recent changes
