I think jlliagre was being kind. Disks have what is called an MTBF - which is sort of an expected operating lifetime in operating hours, or uptime. Consider that your disk may be 'fixed' in the very short term by fsck.
But the disk will continue on its path to complete degradation. Your other disks may also have issues.
We had an old SPARC box - and several replacement disks on hand for this very reason. If you do not have support getting older disk hardware becomes really problematic. We have actually bought parts on Ebay. Our benighted management finally got the message - we now have support: full support.

This isn't causing me a problem, but it is puzzling (& slightly worrying) me.
If I use tar to copy to a tape & the tape is write protected, I only get the message 'tar: tape write err' if there are a few files to copy.

SCSI(7) Miscellaneous Information Manual SCSI(7)
NAME
SCSI, RAID - Small Computer System Interface
SYNOPSIS
dsk#, tape#_d#, cdrom#
DESCRIPTION
The operating system interfaces to disk and tape devices through the Small Computer System Interface (SCSI). SCSI support is limited to
the Compaq-supplied storage devices and certain third-party devices. To determine which named devices are supported in the default system,
refer to the file /etc/ddr.dbase. For example, the following devices are listed therein: Winchester disks: RZ24L, RZ25, RZ25L, RZ25M,
RZ28M, RZ29B, RZ55, RZ56, RZ58, RZ73, RZ74, RX23, RX26, RX33, IOMEGA ZIP, RAID (Redundant Arrays of Independent Disks) SCSI controllers:
HSZ10, HSZ40, HSZ80 Magnetic tapes: TZ30, TZK11, TLZ06, TKZ09, TKZ60, DLT8000, SDT-10000 Media Changers: TL800, ESL9000 Optical disks:
RRD42, RRD43, RRD44
Vendors can add their own devices to ddr.dbase.
Refer to the Software Product Description (SPD) for a given release of the operating system for more information on processor-specific
device support.
Under the operating system, a SCSI device is referred to by a device identifier that is assigned by the operating system. This name has no
relationship to the descriptive name of the device, although in previous releases of the operating system disks such as the RZ74 mapped to
a system-assigned rz# logical name (where # was the instance number of that disk.
Current logical names for SCSI disks and tapes take the forms specified in the rz(8) and tz(7) reference pages, such as dsk? and tape?.
Refer to the dsfmgr(8) reference page for the naming conventions for disks, tapes and other devices, such as CD-ROM readers. Refer to the
hwmgr(8) reference page for information on determining device names and other device data.
SCSI Device Limits
The number of possible target device IDs is determined by the controller type and method of connection, such as a multibus connection using
fibre channel. Refer to the emx(7) reference page for an example of device addressing.
Device Special Files
The dsfmgr command creates device special files for all the devices that are attached to SCSI controllers. This event occurs automatically
on system startup, and no administrative intervention is required unless an event requires that a device be renamed or its I/O be reas-
signed. In such cases, you can use dsfmgr and hwmgr to manage SCSI devices and their associated device special files without the need to
calculate values from their Bus, Target ID, and LUN data.
RESTRICTIONS
The SCSI device driver is not warrantied to operate with optical disks other than the devices listed in /etc/ddr.dbase/. The SCSI driver
attempts to support, on a best-effort basis, disks and magnetic tapes supplied by other vendors.
The following notes apply to the driver's handling of disks from other vendors: These disks are identified using the following command: #
hwmgr -get attribute -a name This command will return the device name SCSI-WWID (World-Wide Identifier) for all devices on the system,
which includes the model name of the device. You can filter the output by specifying categories of devices. Disks are assigned a default
partition table. The default table can be modified by editing the ccmn_rzxx_sizes[8] entry in the /usr/sys/data/cam_data.c file. The
disklabel command can also be used to modify the partition table on an RZxx disk.
