lost file recovery in san jose & the bay area
deleted, formatted, missing, corrupted, and accidentally lost files
if your files are missing, we can help recover them
Documents, photos, videos, archives, business files, accounting records, project folders, and personal data can still be recoverable after accidental deletion, formatting, file system corruption, partition loss, or storage device failure.
With 26+ years of experience, professional recovery tools, and secure lab procedures, Kotar Data Recovery provides lost file recovery for clients across San Jose, San Francisco, and the Bay Area.
why lost files can still be recoverable
When a file is deleted, the data can often remain on the hard drive, SSD, USB drive, memory card, RAID system, or storage volume until it is overwritten. The same can be true after accidental formatting, partition loss, file system corruption, or interrupted transfers.
Our San Jose lab protects the original storage device, creates the safest available recovery copy, analyzes the file system, rebuilds folder structures, and recovers accessible files whenever possible.

deleted file recovery
Deleted files can often be recovered if the storage device has not overwritten the original data. This can include files removed from folders, emptied Trash or Recycle Bin cases, deleted business files, missing photos, deleted videos, and lost project folders.
If the files are important, stop using the device as soon as possible. New activity can overwrite recoverable data and reduce the chance of a successful recovery.
formatted drive recovery
If a hard drive, SSD, USB drive, memory card, or external drive was accidentally formatted, the files can still be recoverable depending on the type of format and whether new data was written afterward.
Do not reinstall the system, copy new files, or continue using the formatted device.
Our engineers evaluate the storage media, protect the original device, and recover files from the safest available copy.
missing or corrupted files recovery
Files can disappear or become corrupted because of file system damage, unsafe ejects, failed updates, malware, interrupted transfers, bad sectors, damaged storage media, or software errors.
We recover missing, inaccessible, unreadable, and corrupted files from personal devices, business systems, external drives, RAID storage, USB drives, SD cards, and other storage media.
what you should do and not do
Stop using the device immediately if important files are missing, deleted, corrupted, or accidentally formatted.
Do not save new files to the same hard drive, SSD, USB drive, memory card, or storage volume.
Do not reinstall the operating system if you need to recover files from the current drive.
Do not run repair utilities such as CHKDSK, Disk Utility First Aid, or fsck on an unstable or physically failing device.
Do not format, erase, or initialize the device if your computer asks you to.
Avoid repeated DIY recovery scans if the device is slow, disconnecting, clicking, or showing read errors.
Contact professional file recovery engineers before making additional changes to the storage device.
