Data Recovery on SCSI Hard Drives - Unresponsive SCSI HDD's

Although these days SCSI hard drives are quite rare, they are still in circulation and we occasionally see them when faults develop. Generally, there are 3 common problems we see on SCSI hard drives.

1. SCSI Drive Reported as 0 Bytes & is Unresponsive

Symptom: Common particularly on Seagate SCSI hard drives, the hard disk spins as normal and is still recognised by the computer. It’s capacity is reported as 0 bytes and it is unresponsive – the drive’s contents can not be accessed.

Cause: This is as a result of a corruption to the hard drive’s firmware (the program the controls that hard drive) and it’s necessary to repair the part of the firmware known as the translator in order to gain access to the data once again.

Recovery: Repairing translator tables is extremely complex and Data Clinic are able to recovery 100% of the data from SCSI drives with this fault.

2. SCSI Drive Reported with no size and ‘Medium Error’

Symptom: Again, common on Seagate SCSI hard drives in particular, the hard drive will power up normally but without any capacity and produce the message ‘Medium Error’. Windows will see the drive but again with no size or access to the data.

Cause & Recovery: The same as 1. above

3. “Start Unit Request Failed”

This is an error produced when the SCSI hard drive starts up and is usually indicative of an electronic or mechanical failure on the SCSI drive. Electronic problems can often be rectified and the data recovered but mechanical problems, especially on SCSI hard drives present a much more challenging problem as frequently the drive will have suffered a head crash and the data on it will not be recoverable.

Recovering the Data from SCSI Hard Drives

Access to the files and folders on SCSI hard drives can be lost for many reasons in addition to the ones listed above. For a general appreciation of these go to our page that explains how hard drives fail. We are able to recover data from most hard drives from most data loss situations, see Data Clinic’s UK locations or call us and arrange for a free collection of your SCSI hard drive.

We've used Data Clinic twice now - once for my son's laptop which held all his University work and suddenly seemed to just die, that was recovered with ease. And then secondly in connection with work when our office computer system backups were somehow corrupted. These people really know their stuff - they are very helpful and professional and quick! Thanks so much for everything.

My company provides IT support to approximately 60 Yorkshire based companies ranging from small 10-15 users up to Enterprise sized organizations. Due to disk failure a client recently lost their entire database. We contacted Data Clinic and within hours a representative was onsite, several hours later the drive was returned, again in person by Data Clinic Manchester. I would not hesitate contacting them again, outstanding service in a market that can mean life or death to a business. 10 stars if there was an option!
